Assembly

In this section, we cover the steps for assembling and disassembling the DeltaQuad Evo.

Unpacking and initial hardware setup

For the initial hardware setup, make sure you have ample room to work. Carefully unpack all components from the flight case and inspect them for any damage. If there is any damage to your vehicle, please document and report it to [email protected].

Mounting the wings

Take the DeltaQuad Evo out of the flight case and place it on a flat surface with the landing gear deployed.

The wing has a large spar near the leading edge and a smaller spar near the trailing edge. In front of the large spar is a keying mechanism in the form of a cuboid.

This keying mechanism prevents mounting the wings on the wrong side.

The wings of the DeltaQuad Evo must be mounted with the wingtips pointing downwards.

Slide the carbon spars of the wings into the corresponding blind holes in the fuselage.

When fully locked, a clicking sound from the wing lock mechanism should be audible, and the wing lock must sit flush with the fuselage.

The wing is not properly installed if the wing lock does not make a clicking sound or does not sit flush with the fuselage.

Disassembly and storage

To disassemble the DeltaQuad Evo, follow the assembly steps in reverse order.

Press down on the wing lock mechanism with your thumb while using the same hand to hold the fuselage in place. With your other hand, pull the wing away from the fuselage.

When storing the fuselage inside the flight case, ensure the landing gear is deployed. It is recommended to transport the DeltaQuad Evo in the flight case.

DeltaQuad Evo Battery

In this chapter, we will cover the DeltaQuad Evo Li-ion battery, including how to handle it, install it in the DeltaQuad Evo, and power up the vehicle.

Battery Handling

This chapter will cover how to properly handle the DeltaQuad Evo Li-ion battery.

The DeltaQuad Evo is compatible with the DeltaQuad Evo Li-ion battery. Using other batteries is not recommended and will impact your warranty.

Safety Notice

Use only the DeltaQuad Dual Battery Charger to charge the DeltaQuad Evo Li-ion battery. Do not use a NiCd or NiMH charger. Failure to follow this guidance may result in a fire, which could cause personal injury or property damage. DeltaQuad assumes no responsibility or liability for damages resulting from the use of third-party chargers.

Charge the batteries only at ambient temperatures between 5°C and 30°C (41°F and 86°F).
Never charge batteries unattended unless you are using a Battery Safe. When charging Li-ion batteries, always remain in constant observation to monitor the process and respond to any potential issues.
Ensure the battery is charged under supervision and away from flammable materials or surfaces.
Disconnect the battery from the charger once it is fully charged.
Do not use a damaged charger.
If you notice a battery starting to balloon or swell, discontinue the charging process immediately. Disconnect the battery and dispose of it safely. Continuing to charge a swollen battery can result in a fire. Similarly, never use a battery that is swollen or ballooned.
Since delayed chemical reactions can occur, it is best to observe the battery as a safety precaution. Battery observation should take place in a safe area outside of any building or vehicle and away from combustible materials.
Wire lead shorts can cause a fire! If you accidentally short the wires, place the battery in a safe area for observation for approximately 1 hour. Additionally, if a short occurs and makes contact with metal (such as rings on your hand), severe injuries may result due to electrical conductivity.
A battery can still ignite even after 1 hour. A battery that emits a hissing sound is almost certain to ignite. Prioritize your safety and that of your surroundings before taking any action.
In the event of a crash, wait 10 minutes to ensure the battery was not compromised before removing and safely disposing of it.
Do not use a battery that has been involved in a crash or sustained any significant impact.
Do not expose the batteries to water. If a battery pack is exposed to water, replace it immediately.

Only place the battery in the vehicle before the flight, and remove it immediately after the flight. Always transport the battery in the dedicated compartment of the flight case or a safe transportation unit, such as a fireproof bag or storage container.

Charging the Battery

This chapter will discuss how to properly charge and store the DeltaQuad Evo Li-ion battery.

Charging the Battery

The DeltaQuad Evo Li-ion battery can be charged within 1 hour at 20 amperes. Charging at this rate may limit the battery’s durability. It is recommended to charge the battery at no more than 15 amperes to maximize its lifetime.

Power on the DeltaQuad Evo Dual Charger.
Plug the yellow XT90 connector from the battery's power cables into the charger.

Take the balance lead, which is the smaller group of cables with the white connector, and plug it into the corresponding balance port on the charger.

With the DeltaQuad Evo Dual Charger, you can charge two batteries simultaneously. Therefore, make sure to connect the cables of each battery to the appropriate channel.

Each channel has two buttons: one for Current and one for Mode.

Set the mode to Charge by pressing the mode button.

We recommend charging the DeltaQuad Evo batteries at a rate of 10 to 15 amperes. You can adjust the charging current by cycling through the available values using the current button.

Press Start.

Your DeltaQuad Evo battery is now charging.

The higher the charging current, the greater the impact on the battery's life expectancy; conversely, the lower the charging current, the longer the battery's life expectancy.

Storage Charge the Battery

When not using the battery for an extended period, it is recommended to store it with the provided DeltaQuad Dual Battery Charger. This will ensure the battery is charged or discharged to 3.7V per cell, which equals 50% of its capacity.

Plug the power and balance cables of the battery into one of the channels on the charger.
Set the mode to Storage by pressing the Mode button.

Press Start.

If the battery is fully charged when using the Storage mode, the charger will discharge the battery to 50% of its capacity. This process can take longer as the discharge power per channel is only 40W.

If the battery is below 50% capacity when using Storage mode, the charger will bring it up to 50% capacity at the set current value.

Storing the Battery

This section describes how to properly store the DeltaQuad Evo Li-ion baterry.

The battery should be stored in a safe, dark location at temperatures between 5 and 30 degrees Celsius.
If the battery is fully discharged or fully charged, perform a storage charge (approximately 50% charge or 3.7V per cell) before long-term storage. Use the Storage mode on the charger for this purpose. Storing batteries at 50% charge helps reduce stress on the cells, which can significantly extend the battery’s overall lifespan.
During long-term storage (3+ months), it is recommended to cycle charge the batteries at least once. Fully charge the battery to 100%, then discharge it to a storage charge level of 50%.
Keep the battery out of reach of children and animals. Avoid placing it near heat sources, such as furnaces or heaters.
Always keep the battery dry and do not expose it to water or any other fluids.
Remove the battery from the UAV when it is not in use.

The lifespan of Li-ion batteries is often measured by the number of charge-discharge cycles they can undergo before their capacity degrades to a certain point, usually around 80% of the original capacity. The DeltaQuad Evo Li-ion battery is rated for 600 or more cycles before noticeable degradation occurs.

Warnings

Set Intermediate Waypoints

This section explains how to properly plan waypoints.

Waypoints are pre-set GPS coordinates that guide the aircraft along a specific path. Each waypoint includes information like altitude, action commands, and other flight parameters. As the DeltaQuad Evo flies autonomously, it follows these waypoints in sequence, adjusting its position to stay on course. This allows for precise navigation during missions such as surveying, mapping, inspections, and cargo drops.

After the Mission Start Action has been planned, Waypoints can be added by clicking anywhere on the map. Select the Waypoint Tool from the Plan Tools on the left side of the screen.

Click anywhere on the map to designate a location for the waypoint.

After placing the Waypoint on the map, the Mission tab in the Mission Editor on the right side of the screen will open.

When clicking on the waypoint number, the Waypoint Summary opens, where all planned waypoints, survey and corridor items, and custom actions are available. Click on any of them to jump to the selected item.

Waypoint type changes the waypoint command. The following Waypoint Commands are available in AMC's Normal Mode.

Waypoint

The vehicle will fly to the User-specified Location and Altitude, and once there, continue on to the next mission item. If there is no mission item after the waypoint, the vehicle will orbit in place at the waypoint’s location.

Orbit (time)

The vehicle will travel to the User-defined Orbit Location and Altitude. Once it arrives, the vehicle will Orbit the area until the specified orbit time expires, then it will proceed to the next mission item.

If the altitude of an Orbit (time) or Waypoint mission item is different from the vehicle’s current altitude, the vehicle will fly directly to the mission item in a straight line. It will not first ascend or descend to match the mission item’s altitude before proceeding forward.

If the vehicle’s climb or descent rate isn’t sufficient to reach the destination mission item on a direct path, it will orbit at the mission item’s horizontal position until it completes the climb or descent to the required altitude.

Orbit Time defines the duration of the Orbit Command, while Orbit Radius determines the size of the Orbit. Exit orbit from provides two choices for where within the Orbit the vehicle will exit.

Orbit (altitude)

The vehicle will fly to the Orbit (altitude) point at its current mission altitude. Only after reaching the horizontal location of the Orbit (altitude) will the vehicle begin climbing or descending to the user-specified altitude. This behavior differs from that of the other mission items described above. When using Orbit (altitude), be especially cautious about terrain collisions.

Orbit (altitude) is suitable for reaching a specific altitude before the flight path continues. This is necessary to avoid terrain collisions if the vehicle cannot achieve the required climb or descent rate directly on route.

Altitude defines the final height of the Orbit Command, while Orbit Radius determines the size of the Orbit. Exit orbit from provides two choices for where within the Orbit the vehicle will exit.

Action

A waypoint that becomes a Custom Action attaches itself to the former Waypoint. This Custom Action can be used, for example, to enable or disable the Stealth Switch or to plan a Cargo Drop. The Stealth Switch and the Cargo Drop will be discussed in a later chapter in this manual.

The Altitude Frame is set to HGT by default. For standard operation, it is recommended to leave this setting as it is.

Set the Altitude of the Waypoint using the Altitude Slider or by typing in the desired value. The Default Waypoints altitude is set in the Mission Start Action and can be adjusted for each Waypoint individually. The following Waypoint automatically inherits the altitude of the previous Waypoint.

Always verify ground elevation using the Terrain Altitude Indicator. A ground collision is indicated when the orange line turns red in the Terrain Altitude Indicator and is also visible on the map.

The Waypoint can be deleted by clicking the Red Trash Bin in the lower right corner of the Mission Editor window. By clicking the Three Dashes in the lower left corner of the Mission Editor window, Geographic Coordinates can be inserted for the Waypoint. Insert the values for the coordinate system of your choice and click Set to confirm the coordinates. Set From Vehicle Position will set the Waypoint to the current vehicle position.

Point of Interest (POI)

Select the POI Tool from the Plan Tools on the left side of the screen. Click on the map where you want to set the POI location. The camera gimbal will automatically point towards the most recently created POI.

In the Mission Editor, located on the right side of the screen, the POI menu displays the following settings.

For the POI the Altitude Frame is set to AGL by default. It is recommended to leave this setting as it is.

The altitude of the POI can be set using the Altitude Slider. In most cases, it is recommended to leave this value at 0 m.
The POI can be deleted by clicking the Red Trash Bin in the lower right corner of the Mission Editor window. By clicking the Three Dashes in the lower left corner of the Mission Editor window, Geographic Coordinates can be inserted for the POI. Insert the values for the coordinate system of your choice and click Set to confirm the coordinates. Set From Vehicle Position will set the Waypoint to the current vehicle position.
To cancel the POI, select the Cancel POI tool from the Plan Tools.

Survey Pattern

This section provides an overview of how to plan a survey pattern.

A Survey Pattern is a pre-planned flight path designed to systematically cover a specific area, essential for missions such as aerial mapping, inspections, and agricultural monitoring. In Intelligence, Surveillance, and Reconnaissance (ISR) operations, using survey patterns offers several key benefits:

Maximized Coverage: Survey patterns like grid or spiral paths ensure that all areas of interest are fully covered, leaving no gaps in data collection. This is crucial in ISR operations for monitoring large areas, tracking enemy movements, or surveying infrastructure.
Improved Efficiency: Pre-programmed flight patterns optimize the UAV’s flight time, allowing for efficient data collection over large areas without unnecessary overlap. This ensures quicker intelligence gathering, which is vital in time-sensitive ISR missions.
Accurate Intelligence: By maintaining consistent flight paths, UAVs can collect high-resolution imagery and sensor data. This enhances situational awareness, enabling decision-makers to assess threats, gather battlefield intelligence, or monitor border areas with precision.
Reduced Human Error: Automated flight patterns reduce the need for constant manual control, minimizing the risk of human error during data collection. This is particularly beneficial in high-risk ISR missions where focus on data analysis is critical.
Adaptability: Survey patterns can be adapted for different terrains or mission needs, such as contour-following for topographic analysis. This versatility is crucial in ISR operations, where varied environments and mission parameters are common.

In ISR missions, the systematic, automated coverage offered by survey patterns ensures comprehensive surveillance, rapid intelligence collection, and enhanced operational decision-making, contributing to mission success.

Payload-specific survey patterns are discussed in their respective sections within this manual.

Once the Mission Start Action has been created, a Survey Pattern can be placed anywhere on the map to autonomously cover an area by flying a predefined path. To do this, click on the Pattern Tool in the Plan Tools located on the right side of the screen and choose Survey.

A Survey item will be created and the Mission Editor on the right side of the screen will display the Survey Settings.

For ISR operations, it is recommended to choose Manual (no camera specs) as this provides direct access to the Survey Altitude and Spacing without the need to set the Overlaps.

Survey settings for specific mapping payloads are covered in their respective chapters.

The Survey area selector offers predefined shapes for the Survey Pattern.

Rectangle Tool

Creates a rectangular survey on the map. Use the outer vertices to shape the form and the green vertex in the middle of the pattern to reposition it. Clicking the plus sign on the survey edge adds additional vertices.

Circle Tool

Creates a circular survey on the map. Use the outer vertex to expand or contract the shape, and the green vertex in the middle of the pattern to reposition it.

Trace Tool

The Trace Tool lets the operator draw a survey form by clicking anywhere on the map. Use the outer vertices to shape the form and the green vertex in the middle of the pattern to reposition it. Clicking the plus sign on the survey edge adds additional vertices.

Click on a vertex with the left mouse button to remove it or enter geo-coordinates for that specific point.

During tracing, the map can be dragged by holding down the Ctrl key on the keyboard and dragging the map with the right mouse button.

Once tracing is complete, confirm by clicking the Done Tracing button in the Mission Editor.

Load KML/SHP file

This provides the option to import KML or SHP files for the survey pattern.

Altitude sets the altitude of the Survey Pattern, which is usually relative to the Home Position.

Spacing determines the distance between the transects (trajectories within the green survey area). Spacing on the left side is 50 meters, and spacing on the right side is 150 meters.

The Trigger Distance can be ignored. Payload-dependent survey planning will be discussed in the dedicated chapters.

Pattern Options provide additional settings for the Survey.

Set the Pattern angle by moving the slide or entering a value. On the left side, the Pattern angle is 90 degrees, and on the right side, it is 180 degrees.

The Turnaround Distance refers to the horizontal distance the drone travels beyond the survey area's edge at the end of a transect before making a turn to start the next parallel transect. This buffer provides the drone with enough space to turn, and align itself accurately for the next pass, ensuring smooth transitions between flight lines. Set the Turnaround Distance by moving the slider or entering a value. On the left side, the Turnaround Distance is 50 meters, and on the right side, it is 300 meters.

Rotate Entry Point determines the vehicle's entry and exit locations for the survey. Click the button to toggle through all possible positions.

The Options tab provides four additional options for the survey item.

Refly at a 90-degree offset adds vertical trajectories to the horizontal ones. This is typically used for mapping missions, as it collects twice the amount of data, which is useful for creating a 3D map, for example. This tool can also be useful for ISR operations, as it covers the area in question twice.

The Images in turnarounds option is important for survey missions using a mapping payload, such as the Sony A7R Mark IV. This option will be discussed in the dedicated payload chapter and is not relevant to ISR operations.

Fly alternate transects - When not selected the vehicle is flying the exact pattern line after line.
The DeltaQuad Evo has less space between the two lines to perform the turnaround and re-enter the survey area. When Fly alternate transects is enabled the vehicle will fly constantly skipping one line. When reaching the end, the DeltaQuad Evo will fly back and follow the lines it previously skipped. This option will be discussed in the dedicated payload chapter and is not relevant to ISR operations.

Relative altitude: When enabled, altitudes are relative to the home point. When disabled, altitudes are measured above mean sea level (AMSL).

Be cautious and always double-check ground elevation.

The Survey item can be deleted by clicking the Red Trash Bin in the lower right corner of the Mission Editor window.

By clicking the Three Dashes in the lower left corner of the Mission Editor window, the option Edit Position appears. Insert the values for the coordinate system of your choice and click Set to confirm the coordinates.

Always verify the ground elevation using the Terrain Altitude Indicator. A ground collision is indicated when the orange line turns red in the Terrain Altitude Indicator.

The Vehicle follows terrain option allows the aircraft to maintain a constant distance from the ground. If the ground elevation changes, the vehicle adjusts its altitude accordingly. This option will be discussed in the dedicated payload chapter and is not relevant to ISR operations.

A fixed-wing aircraft has limited capabilities to follow ground elevation due to its need for constant forward movement to generate lift. This continuous motion restricts its ability to make quick altitude adjustments. Additionally, fixed-wing aircraft have a limited climb and descent rate, meaning they cannot rapidly adapt to sudden changes in terrain elevation, unlike multirotor drones that can hover and change altitude more quickly.

The Presets tab allows you to save settings as a preset for frequent use and load existing presets.

Mission End Action

This section explains how to properly plan a transition and VTOL landing.

The DeltaQuad Evo is a VTOL UAV capable of Fixed-wing Flight (Aero Mode) and Vertical Takeoff and Landing (Hover Mode). Unlike traditional UAVs requiring a landing runway, the DeltaQuad Evo transitions seamlessly from Fixed-wing Mode to Multirotor Mode for VTOL landings. During this transition, the aircraft switches from using its forward thrust for horizontal flight to relying on its rotors for vertical lift, allowing it to hover and land precisely.

This capability offers several advantages:

No runway required: It can land in confined spaces, making it suitable for urban, mountainous, or remote areas.
Versatile operations: The vehicle can fly long distances in efficient Fixed-wing Mode and switch to Multirotor Mode for precise VTOL landings.
Reduced risk: VTOL landings reduce the risk of damage from hard landings or rough terrain.

After all Intermediate Waypoints have been planned, click the End tab in the Mission Editor on the right side of the screen. Three options for the Mission End Action will be displayed.

By choosing either Add Orbit Land Pattern or Add Straight Land Pattern, the following two options will be available if the vehicle is connected to the AMC.

It is recommended to choose Move land to vehicle, as it will set the touchdown of the landing to the takeoff location. If the vehicle is not connected to AMC, choose Click on map to set landing location and set the landing location manually.

Orbit Land Pattern

When choosing Add Orbit Land Pattern, AMC automatically creates the Landing Pattern as shown on the map.

An Orbit Land Pattern involves the vehicle flying in an Orbit around a designated location while gradually descending to a set altitude. Once it reaches the predetermined altitude, the vehicle leaves the Orbit and heads toward the landing location, where it transitions from Fixed-wing Mode to Multirotor Mode, slowing down and hovering directly above the designated landing area. From there, it performs a vertical descent for a precise VTOL landing. This method allows for controlled, safe landings, especially in confined or challenging environments.

The minimum Landing Altitude the vehicle descends to needs to be set at least 25 meters above the highest obstacles in the landing area. For example, if the average tree height in the landing area is 10 meters, the Landing Altitude must be set to at least 35 meters.

At every stage in the fixed-wing portion of the flight, a vertical separation of at least 25 meters above the highest obstacle must be maintained.

When choosing Add Orbit Land Pattern, the following window appears on the right side of the screen, providing options for the Orbit of the Landing Pattern.

The Altitude Frame is set to HGT by default. For standard operation, it is recommended to leave this setting as it is.

Altitude Frame Options

Set the Altitude (Land Altitude) to at least 25 meters above any obstacle in the landing area.
It is recommended to leave the Radius at 100 meters. 75 meters is possible in calm winds.

The indicated Orbit in the case of a loiter down is only an estimate. The DeltaQuad Evo may drift outside this Orbit by up to 100 meters based on wind conditions and the vehicle's position. Therefore, thoroughly inspect the entire landing area and its surroundings.

The Orbit Direction will be clockwise by default. This option can be disabled, allowing the Orbit position to be set to the north, which enables a counter-clockwise Orbit Direction.

The direction of the Landing Pattern will be automatically set to match the Takeoff and Transition Direction, assuming that the Transition Direction was planned so that the vehicle can perform the Takeoff and Transition into the wind. The Orbit and, therefore, the Landing Direction can be repositioned if a crosswind landing is necessary. This procedure should only be performed in wind conditions below 5 m/s. The Set to takeoff heading button can be used to realign the landing direction to the vehicle's heading.

The Move land to vehicle option sets the Landing Location to the vehicle’s position when the vehicle is connected to AMC. This can be convenient if the mission was initially planned without the vehicle being connected.

The Mission End Action can be deleted by clicking the Red Ttrash Bin in the lower right corner of the Mission Editor window. By clicking the Three Dashes in the lower left corner of the Mission Editor window, the option Move to vehicle position appears. This option is the same as Move land to vehicle.

When choosing Edit Land Position, a window will open where geographic coordinates can be inserted for the Landing Location. Insert the values for the coordinate system of your choice and click Set to confirm the coordinates. Set From Vehicle Position will set the Landing Location to the current vehicle position.

Straight Land Pattern

When choosing Add Straight Land Pattern, AMC automatically creates the Landing Pattern as shown on the map.

A Straight Land Pattern involves the vehicle descending from a set Land Start altitude to the Transition altitude in a straight line. Once it reaches the predetermined Transition altitude, the vehicle heads toward the landing location, where it transitions from Fixed-wing Mode to Multirotor Mode, slowing down and hovering directly above the designated landing area. From there, it performs a vertical descent for a precise VTOL landing. This method allows for controlled, safe landings, especially in confined or challenging environments.

The minimum Transition altitude or Landing Altitude the vehicle descends to needs to be set at least 25 meters above any obstacles in the landing area. For example, if the average tree height in the landing area is 10 meters, the Landing Altitude must be set to at least 35 meters.

When choosing Add Straight Land Pattern, the following window appears on the right side of the screen, providing the following Settings.

The Altitude Frame is set to HGT by default. For standard operation, it is recommended to leave this setting as it is.

Altitude Frame Options

Set the Land Start altitude. This is the altitude the vehicle starts its descent to the set Transition altitude.
Set the Transition altitude to at least 25 meters above any obstacle in the landing area.
The direction of the Straight Land Pattern will be automatically set to match the Takeoff and Transition Direction, assuming that the Transition Direction was planned so that the vehicle can perform the Takeoff and Transition into the wind. The Straight Land Pattern can be repositioned if a crosswind landing is necessary. This procedure should only be performed in wind conditions below 5 m/s. The Set to takeoff heading button can be used to realign the landing direction to the vehicle's heading.

The Move land to vehicle option sets the Landing Location to the vehicle’s position when the vehicle is connected to AMC. This can be convenient if the mission was initially planned without the vehicle being connected.

The Mission End Action can be deleted by clicking the Red Trash Bin in the lower right corner of the Mission Editor window. By clicking the Three Dashes in the lower left corner of the Mission Editor window, the option Move to vehicle position appears. This option is the same as Move land to vehicle.

When choosing Edit Land Position, a window will open where geographic coordinates can be inserted for the Landing Location. Insert the values for the coordinate system of your choice and click Set to confirm the coordinates. Set From Vehicle Position will set the Landing Location to the current vehicle position.

The Land start item can be dragged in every direction. If the Land start item is too close to the Transition item where the vehicle is not able to reach the set Transition altitude, a warning will appear on the upper screen, and the orange flight path will turn red. To solve this, lower the Land Start altitude or drag the Land start item further away from the Transition item.

Add Loiter

Mission Upload

After the mission plan has been created, make sure to verify the ground elevation. The Terrain Altitude Indicator displays the mission height (orange top line) and the ground elevation (green ground profile).

After the mission has been planned and all necessary items thoroughly checked, the mission plan can be uploaded to the vehicle by clicking on the Upload Mission button.

Geofences

This section describes the use and functionality of geofences.

A geofence is a virtual boundary set around a specific geographic area. It restricts where the UAV can fly, often for safety, regulatory compliance, or privacy reasons. If a UAV approaches this boundary, it can trigger automated actions, like alerting the operator, pausing, or returning to a safe area. Geofencing helps prevent UAVs entering restricted zones, such as airports, military areas, or other sensitive locations.

Setting a Geofence in the Safety Tab

One or more geofences can be placed in the Plan View and uploaded to the vehicle. This is possible with or without a takeoff, waypoint, or landing item being present. This is beneficial when operating the vehicle with the Quick Takeoff functionality while requiring complex geofencing.

A faster and simpler way to create a geofence is to use the Geofence Failsafe Trigger option in the Safety tab, as explained in the following section.

Navigate to the Geofence option in the Safety tab: AMC Menu -> Vehicle Overview -> Safety -> Geofence Failsafe Trigger.

When AMC is running in Normal Mode, the Action on breach tab provides the following four options to choose from. Set the action required for the planned operation.

When enabling Max Radius, a geofence will be placed with the DeltaQuad Evo at its center. Set the values for Max Radius and Max Altitude (HGT) in the respective fields.

The Max Altitude is referenced to the takeoff location (HGT), not above ground level (AGL). Special care must be taken when operating in an area with varying ground elevations. For more information, please read the chapter Geofence Failsafe Trigger.

Setting a Geofence in the Plan View

Polygon Fences

Go to the Plan View and navigate to the Extra tab in the Mission Editor on the right side of the screen: AMC Menu → Plan View → Extra.

In the Extra tab, two geofence options are available: Polygon Fences and Circular Fences. Add a geofence by clicking the plus sign next to the desired geofence shape. A geofence will be positioned at the center of the map.

The Polygon Fence can be repositioned by dragging the geofence while holding the inner vertex (green point). Clicking on the outer (white) vertices gives the option to remove a vertex or enter the geocoordinates for that specific point. The outer vertices can also be dragged in any direction to shape the polygon into the desired form.

Clicking any of the plus signs on the geofence adds another vertex.

Hold and drag any of the vertices to shape the polygon.

Hold and drag the inner green vertex to reposition the fence in any direction.

The geofence can be set to be inclusive or exclusive. By default, the Type is set to Inclusion. Change the Type by selecting Exclusion in the respective tab.

Inclusionary geofence: A geofence where the vehicle stays within the defined area; an action is triggered before breaching and leaving the area.
Exclusionary geofence: A geofence that defines an area the vehicle shall not enter; an action is triggered before breaching and entering the area.

If a height limit for the geofence is required, this can be set in the Geofence Failsafe Trigger tab in the Safety settings. Enable Max Altitude (HGT) and set the desired value. The Action on breach will be triggered when the vehicle crosses the set altitude.

The Max Altitude is referenced to the takeoff location (HGT), not above ground level (AGL). Special care must be taken when operating in an area with varying ground elevations.

When the Extra tab (Geofences) is selected, two Plan Tools on the left side of the screen are available. The full functionality of these tools can be reviewed in the chapter Plan View. The File option allows you to save the geofence(s), and the Center option provides multiple ways to center the view.

Circular Fences

When adding a Circular Fence, it will be placed at the center of the map.

The radius can be adjusted by holding and dragging the outer vertex left or right. Alternatively, a value for the radius can be set in the Radius tab in the Mission Editor on the right side of the screen.

The Circular Fence can be repositioned by holding and dragging the inner vertex in any direction.

As with the Polygon Fence, the Circular Fence Type can be set to either inclusive or exclusive.

If a height limit for the geofence is required, this can be set in the Geofence Failsafe Trigger tab in the Safety settings. Enable Max Altitude (HGT) and set the desired value. The Action on breach will be triggered when the vehicle crosses the set altitude.

The Max Altitude is referenced to the takeoff location (HGT), not above ground level (AGL). Special care must be taken when operating in an area with varying ground elevations.

When the Extra tab (Geofences) is selected, two Plan Tools on the left side of the screen are available. The full functionality of these tools can be reviewed in the chapter Plan View. The File option allows you to save the geofence(s), and the Center option provides multiple ways to center the view.

Inclusive and Exclusive Geofences

When an inclusive geofence is planned with the DeltaQuad Evo outside the geofence, the following two scenarios can occur:

The vehicle will not be able to arm while on the ground, as it is outside the geofence.

The vehicle will trigger the Action on breach when airborne, as it is outside the geofence.

When a exclusive geofence is planned with the DeltaQuad Evo inside the geofence, the following two scenarios can occur:

The vehicle will not be able to arm while on the ground, as it is inside the geofence.

The vehicle will trigger the Action on breach when airborne, as it is inside the geofence.

Exceptions

As stated in this manual, when an RTL command is triggered, the vehicle will return in a straight line to its designated landing point. If an exclusionary geofence or the boundary of a complex inclusionary geofence lies between the vehicle and the landing point, the vehicle will ignore the geofence and pass through it during its return.

In Altitude and Position Mode, the vehicle will breach both inclusionary and exclusionary geofences for a small distance until the RTL command is triggered. The system has a delay in responding to a geofence in these modes because the system needs to verify for a longer period that it has breached the geofence.

Rally Point and Breach Return Point are not supported by the DeltaQuad Evo.

(When AMC is running in Advanced mode, Rally Points are available in the Plan Tools on the left side of the screen, and the option to set a Breach Return Point is available in the Mission Editor on the right side of the screen. These options are not supported on the DeltaQuad Evo.)

Pre-flight Checks

This chapter discusses all items of the pre-flight checklist.

The pre-flight checklist is a comprehensive list of tasks and inspections performed before taking off to ensure that the DeltaQuad Evo is ready for safe and efficient operation. It typically includes verifying equipment functionality, checking battery levels, confirming GPS signals, inspecting hardware for damage, and reviewing flight plans.

The pre-flight checklist is crucial because it helps prevent mechanical failures, ensures that all systems are operational, and minimizes the risk of in-flight issues. By systematically verifying each item, operators can enhance safety, improve flight performance, and reduce the likelihood of accidents or operational disruptions.

Planned Mission

Mission Compliance: Ensure the mission conforms to all local laws, regulations, and airspace restrictions.
Mission Plan: Verify the mission was planned according to the guidelines outlined in the Plan section of this manual.
Terrain Altitude: Verify that altitudes are set appropriately against terrain height for the entire flight path.
Obstacle Clearance: Maintain a vertical separation of at least 25 meters above the highest obstacle at every stage in the fixed-wing portion of the flight.
Path Clearance: Verify the mission path is free of obstructions for at least 200 meters in each horizontal direction.
VTOL Operations: Confirm proper application of VTOL takeoff and landing procedures.
Takeoff: Ensure the takeoff location is free from obstructions up to the transition altitude for 500 meters in the transition direction and 200 meters in every horizontal direction. In case of a failed airspeed sensor, the vehicle will fully engage the pusher motor for 25 seconds and fly in a straight line before aborting the transition due to a failure to achieve the transition airspeed.
Landing Site: Verify the landing site is free of obstacles and structures taller than the transition altitude.
Orbit Land Pattern: Ensure the orbit and landing approach are clear and maintain at least 25 meters above any obstacle.
Wind Direction: Align the vehicle’s takeoff and landing paths against the wind, pointing the vehicle in the direction from which the wind is coming.

Quick Takeoff (if applicable)

Land Approaches: Ensure obstacle-free sectors are selected for the landing approach. The vehicle will automatically perform the back transition to multirotor mode into the wind, or get as close as possible to this direction given the limitations of the selected sectors.
VTOL Operations: Plan takeoff altitude to be 15 meters above obstacles and landing altitude 25 meters above obstacles.
Holding Pattern: Set VTOL takeoff orbit with at least 25 meters of clearance above obstacles. The orbit's altitude is always 80 meters relative to the takeoff location.
Takeoff: Ensure the takeoff location is free from obstructions up to the transition altitude for 500 meters in the transition direction and 200 meters in every horizontal direction. In case of a failed airspeed sensor, the vehicle will fully engage the pusher motor for 25 seconds and fly in a straight line before aborting the transition due to a failure to achieve the transition airspeed. Strong winds can shift the orbit in any direction, altering its shape. For example, due to wind influence, a circular orbit may change in its shape to become more oval.
Wind Direction: Align the vehicle’s takeoff and transition against the wind, pointing the vehicle in the direction from which the wind is coming.

Airframe

Maintenance Cycles: Ensure the vehicle is within preventive maintenance intervals.
Regulatory Compliance: Confirm the airframe complies with all local rules and regulations and is permitted to fly the intended mission.
Parts Inspection: Check for damage, dirt, secure mounting, and fastening:
- Fuselage: Undamaged and clean.
- Skid Antennas: Undamaged.
- Propellers: Correctly mounted, securely fastened, and free of damage and dirt.
- VTOL Arms: Properly mounted and fastened.
- VTOL Motors: Spinning freely, no play in the bearings.
- Pusher Motor Pod: Correctly mounted, securely fastened.
- Pusher Motor: Spinning freely, no play in the bearings.
- Wings: Mounted securely, undamaged, and clean.
- Wing Tip LEDs: Clean and operational (if applicable).
- Elevons: Moving freely, undamaged, and clean.
- Payloads: Correctly mounted, and payload-dependent checks completed (SD cards/USB sticks installed if required).
Battery Check: Ensure the flight batteries are undamaged, with no dents or swelling, and that all cables and connectors are intact. When flying with two batteries, ensure both are fully charged and have the same charge level.
Landing Gear: Free of damage and dirt. The vehicle should be launched from a solid surface free of mud as the landing gear can collect mud and add weight to the vehicle.
Hatch: Free of damage and dirt.

Cold Weather Considerations (Below 5°C)

Ice, Snow, or Mud: Ensure the landing gear is free from ice, snow, or mud as this can result in the landing gear legs freezing onto the VTOL arms not being able to deploy during landing.
Solid Surface Launch: The vehicle should be launched from a solid surface free of snow or mud.
Pitot Tube Icing: Verify the pitot tube is ice-free.
Battery Temperature: Batteries must be heated above 10°C before takeoff.

Before Closing Hatch

Sunlight Exposure: Avoid exposure to direct sunlight when idle for more than 5 minutes to prevent overheating.
Flight Batteries: Ensure batteries are properly installed, power connectors securely connected, and fully seated. When operating with an auxiliary battery, ensure the locking latch is rotated 90 degrees to secure the battery.
Payloads: Verify payloads are installed and detected. Custom payloads must not exceed 3 kg in total.
APDS Payload: Ensure APDS cargo cannot move excessively during flight. (If applicable, use compartment dividers.)
System Status: The DeltaQuad Evo status OLED reads Ready to fly.

After Closing Hatch

Hatch Security: Ensure the hatch is secured, with the closing mechanism pushed down, locked, and sitting flush with the fuselage.
Vehicle Positioning: Position the vehicle on the designated takeoff/landing zone, facing into the wind.

Before Takeoff

Weather Conditions: Ensure weather conditions are within mission tolerances. Verify that wind speed and gust limits are within safe VTOL and fixed-wing operation parameters.
Communications Check: Confirm communication between UAV and GCS is reliable. If in use, check the VPN connection.
GCS Warnings: Verify no warnings appear on the GCS.
GPS Lock: Ensure stable GPS lock with at least 10 satellites.
Failsafe Settings: Confirm safety features are set correctly, and failsafe settings are properly configured in case of communication loss or low battery.
Physical Orientation: The vehicle's current physical orientation should match the heading observed on GCS.
Battery Check: Verify in AMC that the flight battery indicator shows a full charge (greater than 95%).
Complete AMC Preflight checklist: Ensure all items are completed, including:
- Ground Equipment Charge: Ensure ground equipment has sufficient charge to perform the mission.
- Airspeed Sensor: Verify positive airspeed in telemetry. To test provide airflow in front of the pitot tube.
- Control Surfaces Check: Perform control surfaces functionality check.
- Mission Upload: If applicable confirm the mission plan is uploaded.
- Clear Takeoff Area: Check for a clear takeoff area and airspace.

Interactive Preflight checklist in AMC

To access the interactive Preflight checklist in AMC, click on the Vehicle Status Indicator in the screen's upper left corner.

The Vehicle overview window opens. Click on the Preflight checklist tab in the lower-left corner of the window.

Go through each step of the Preflight checklist. The checklist can be reset to start over by clicking on the reset icon on the upper-right side of the screen.

You can enforce the Preflight checklist. Navigate to AMC menu -> Setting -> General -> Fly View.

Before each flight, the pre-flight checklist from the manual needs to be completed. The interactive Preflight checklist in AMC is part of that checklist, as the actuators will be checked, for example. It is NOT sufficient to only go through the interactive Preflight checklist in AMC.

Manual Control

This section explains how to manually control the DeltaQuad Evo.

Once the vehicle is launched and has transitioned to fixed-wing mode, you can control it using the following methods.

Repositioning the Vehicle and Changing the Altitude

While the vehicle is in flight, you can select the or Fig 8 command from the Flight Tools on the left side of the screen.
Tap anywhere on the map to choose the location for the Orbit or Fig 8.
When issuing an Orbit or Fig 8 command, the altitude can be adjusted. The Altitude Slider will appear on the right side of the screen, allowing you to select a new altitude.
After confirming the command, the vehicle will change course to the chosen location and adjust to the selected altitude.

If a loss of connection occurs during repositioning the vehicle with the Orbit and Fig 8 command, the Data Link Loss Failsafe Action will be activated after the timeout. When disabled the vehicle will remain in Hold mode until the data link is re-established. If the data link cannot be restored, the vehicle will remain in Hold mode until the Low Battery Failsafe Trigger activates. If the failsafe action is set to Return mode, the vehicle will return to the designated landing location.

Mission plan execution can be paused using the Hold command. Reposition the vehicle manually and adjust altitude using the Orbit and Fig 8 commands. You can resume the mission at the selected active waypoint at any time by using the Mission command.

When the vehicle is following a mission path, it will always maintain the altitude defined in the mission plan. When resuming a mission, the vehicle will immediately adjust its altitude to match the currently active waypoint.

At any point during the flight, the Return command can be issued to bring the vehicle back to the designated landing location.
Airspeed can be changed with the Change Speed command.

Joystick Control - Fixed-wing Mode

For inexperienced pilots, joystick controls can feel counterintuitive. It is recommended to practice joystick operation nearby while maintaining a safe altitude.

For joystick (manual) control, the flight mode must be changed. Press the Mode button in AMC's Top Bar. Two options will be offered: Altitude and Position mode.

Flight modes explained

Altitude mode - The DeltaQuad Evo will automatically hold its altitude and direction until changed by the stick input. For flight stabilization and navigation, it will only rely on the IMU and not make use of the compass and GPS.
Position mode - The DeltaQuad Evo will automatically hold its altitude and direction until changed by the stick input. For flight stabilization and navigation, it relies on the IMU and makes use of the compass and GPS.

After activating either Altitude or Position mode, the vehicle will fly in a straight line at its current altitude until stick input is given.

If the vehicle loses connection to the GCS while flying in Altitude or Position mode, it will automatically initiate a Return command after a 5-second timeout to prevent a flyaway, regardless of the Safety settings.

Altitude Mode and Position Mode can be paused using the Hold command. The Return command can be issued to bring the vehicle back to the planned landing location.

In fixed-wing mode, the vehicle can be controlled with the right joystick input.

Moving the right joystick left or right will cause the vehicle to change direction.

Moving the joystick forward or backward controls the vehicle's altitude.
Pushing the joystick forward decreases altitude.
Pulling the joystick backward increases altitude.

Under NO circumstances attempt to fly the DeltaQuad Evo in Manual Mode! Do not assign the Manual Mode to any of the available buttons on the controller.

Nudging

Nudging refers to making small manual adjustments to an automated flight path, typically during the landing descent. This feature allows operators to slightly alter the course or trajectory of the DeltaQuad Evo without fully taking over manual control. It's commonly used to ensure smoother landings, especially in cases where minor corrections are needed due to environmental factors like wind or obstacles

After the Evo transitions from fixed-wing mode to multirotor mode, the vehicle will deploy the landing gear and descend to the planned landing point.

The operator can halt the descent by pushing the left joystick forward.

The vehicle will maintain its altitude and position. The right joystick controls the vehicle's position. Moving the joystick forward, backward, left, or right changes the vehicle's position relative to its current heading.

The left joystick controls the vehicle's descent and heading. Moving the joystick up will halt the descent while returning returning the joystick to the middle position or moving it down will resume the descent. Moving the joystick left or right changes the vehicle's heading (yaw).

The maximum default hover time of the DeltaQuad Evo is 90 seconds. After 90 seconds the vehicle will force-land at its current location.

Joystick Control - Multirotor Mode

For joystick (manual) control, the flight mode must be changed. Press the Mode button in AMC's Top Bar. Two options will be offered: Altitude and Position mode.

Flight modes explained

Altitude Mode: The DeltaQuad Evo will automatically maintain its altitude while the pilot controls the horizontal direction. It relies solely on the IMU for stabilization and navigation, without utilizing the compass or GPS. During Altitude mode, drift can occur due to wind influences.
Position Mode: The DeltaQuad Evo will hold both its altitude and position until adjusted by stick input. For stabilization and navigation, it uses the IMU along with the compass and GPS for enhanced accuracy.

Altitude mode provides faster movement in multirotor mode compared to Position mode.

After activating either Altitude or Position mode, the vehicle will hover in place until stick input is given. In Altitude mode, more drift can be expected.

The left joystick controls the vehicle's altitude and heading.
Moving the joystick forward will increase the altitude.
Moving the joystick backward will decrease the altitude.
Moving the joystick left or right changes the heading (yaw) of the vehicle.

The right joystick controls the position of the vehicle. Moving this joystick, forward, backward, left, or right changes the position of the vehicle relative to its current heading.

The maximum default hover time of the DeltaQuad Evo is 90 seconds. After 90 seconds the vehicle will force-land at its current location.

When the handheld controller is unplugged from the Toughbook in-flight while using Altitude or Position mode, the vehicle will enter Failsafe mode. By default, this is set to Return to Launch.

Plug the handheld controller back in to the Toughbook and reselect Altitude or Position mode to continue. Alternatively, you can pause the Failsafe action and reposition the vehicle using an Orbit command.

Inspect the ship from which you plan to take off.
Identify the most suitable takeoff and landing area that offers sufficient space and is as far as possible from any metallic objects.
Determine the optimal position for the Ground Control Station and any optional antennas, if applicable.
Ensure that a clear line of sight between the vehicle and the antennas can be maintained at all times.
Power up the DeltaQuad Evo and the GCS (AMC).
Set AMC to .

Determine the wind direction and position the vehicle so its nose faces into the wind.

Manual Takeoff and Transition

Ships are typically constructed with large amounts of metal, especially steel, in their hulls and superstructures. This metal composition can significantly impact the performance of UAV magnetometers.

A magnetometer is a sensor that detects magnetic fields and is often used in UAVs for navigation or other specialized applications. When a UAV operates near a large metal object, like a ship, the metal can create distortions in the Earth's magnetic field. This distortion can cause the magnetometer to give inaccurate readings, which may affect the UAV’s navigation systems, especially if they rely on magnetic heading for orientation.

For this reason, Altitude mode is the preferred flight mode for manually taking off from a ship. In Altitude mode, the UAV does not rely on its compass or GPS, making it less susceptible to these magnetic interferences. This allows for more stable manual control during takeoff in environments with strong magnetic disturbances, such as a metal ship.

Select Altitude Mode via the Mode button.

Press Disarmed at the top of the menu bar.

Arm the vehicle by pressing and holding the confirmation button.

Press the left stick upwards to ascend.
Continue the ascent to 15 meters altitude or above the highest point of the ship's structures. This value also needs to be adjusted based on the height of the ship's deck. Once exposed to the wind, the vehicle will begin to drift.
Correct the drift with stick input until the ship's structures are fully cleared. The right joystick controls the vehicle's position. Moving the joystick forward, backward, left, or right adjusts the vehicle's position relative to its current heading.

The left joystick controls the vehicle's altitude and heading. Moving the joystick up will increase the altitude while moving it down will decrease the altitude. Moving the joystick left or right changes the vehicle's heading (yaw).

During the ascent, it is crucial to keep the nose aligned into the wind, as this provides the most stability for the vehicle during takeoff and transition.. This alignment also allows the Transition command to be executed into the wind without needing to realign the vehicle.

There are two possibilities to proceed from this point.

1. Position Mode

Once the ship's structure is cleared and there is sufficient distance between the ship and the vehicle, switch to Position mode via the Mode button.

Position mode provides enhanced navigational accuracy and stability by utilizing GPS and the magnetometer. However, a disadvantage is that the ship's metal can still create interference in the magnetometer.

This mode provides enhanced navigational accuracy and stability by utilizing GPS and the magnetometer. However, a disadvantage is that the ship's metal can still create interference in the magnetometer.
When in Position mode and the vehicle is aligned with its nose into the wind, verify for the last time that the transition path is free of obstacles, then issue the transition command.

Once the transition is complete, typically after 2 to 3 seconds, ascend to a safe altitude by pulling the right joystick backward, as it controls altitude during fixed-wing flight.

- Altitude
- Windspeed and direction
- Groundspeed and airspeed

Once a safe altitude and location are reached, issue the Hold command. The vehicle will orbit its current location at the present altitude with a radius of 100 meters.

2. Altitude Mode

If magnetic interference is strong, it is recommended to transition to fixed-wing mode while in Altitude mode, as this mode primarily relies on the IMU (Inertial Measurement Unit) without using the compass or GPS.

In Altitude mode, special care must be taken with regard to altitude readings, as accuracy will vary in this mode. Altitude mode relies heavily on barometric sensors (altimeters) and sometimes the Inertial Measurement Unit (IMU) for estimating altitude. These sensors can be affected by environmental factors, such as temperature and air pressure changes.

Once the ship's structure is cleared and the vehicle is aligned with its nose into the wind, verify for the last time that the transition path is free of obstacles, then issue the transition command.

Once the transition is complete, typically after 2 to 3 seconds, ascend to a safe altitude by pulling the right joystick backward, as it controls altitude during fixed-wing flight.

- Altitude
- Windspeed and direction
- Groundspeed and airspeed

Once a safe altitude and location are reached, issue the Hold command. The vehicle will orbit its current location at the present altitude with a radius of 100 meters.
Select Position mode via the Mode button, as the vehicle has sufficient clearance and should be outside the ship's magnetic interference.

1. Landing - Transition to Multirotor Mode

Set an Orbit with a clear line of sight.
Identify the landing trajectory aligned into the wind, with a safe bailout option.
Reposition the orbit to align with the identified landing trajectory.
Lower the orbit’s altitude to a safe landing height of at least 15 meters above the ship's deck.
When the DeltaQuad Evo is facing the direction of the landing trajectory, switch to Altitude mode.

Guide the vehicle to the landing zone while maintaining its altitude with the right joystick.

Transition to Multirotor Mode at a safe distance from the landing zone (between 200m and 25m). Higher wind speeds require a shorter distance to complete the transition.

2. Landing - Multirotor Mode Descent to 5m

3. Landing - Multirotor Mode Descent 5m to Touchdown

When positioned above the landing zone, account for the deck's tilt and movement.
Adjust the vehicle's heading so that its wings are positioned to avoid hitting the deck due to its rolling.
Time the landing with the waves to ensure touchdown occurs at the deck's lowest point.
After touchdown, be prepared to manually disarm the vehicle through emergency actions if necessary. If the ship's movements are minimal, the vehicle will disarm itself within 2 seconds after touchdown.

GPS-Denied Operations

This section will describe the steps required for GPS-denied operations.

Preparations

Thoroughly review the chapter on .
A good knowledge of the mission area is required to fly in GPS-denied areas, as the vehicle’s position will be estimated based on visual identification of landmarks and other prominent features.

To navigate in GPS-denied areas, the use of an ISR payload is mandatory, as it enables visual identification of landmarks. Refer to the dedicated payload manual for proper use and handling of .

The takeoff and landing area should have sufficient space with as few obstacles as possible.
Power up the DeltaQuad Evo and the GCS (AMC).
Set AMC to .
Complete the .

The functions to disable GPS Fusion, set the Home Position manually, and allow takeoff without GPS lock, must be enabled in AMC Menu -> Vehicle Overview -> More -> GPS Advanced Settings.

Disable GPS Fusion

GPS Fusion - GPS data is combined with other sensor data to enhance the accuracy and reliability of the drone's navigation and positioning systems. When GPS Fusion is disabled, the vehicle position based on the raw GPS data will be displayed as a grey arrow in AMC. The blue arrow shows the estimated vehicle position based on the IMU, compass, and wind speed sensor.

If no GPS signal is available, only the blue arrow will be displayed.

When operating in GPS-denied areas, it is recommended to disable GPS Fusion before takeoff.

Click the GPS icon in the menu bar and Disable GPS Fusion.

Set Home Position Manually

If a GPS signal is available during the start-up of the vehicle, the DeltaQuad Evo will set the Home Position automatically before disabling GPS Fusion. If no GPS signal is available, the Home Position must be set manually. When the function to set the Home Point manually is enabled, simply click on the waypoint displaying an H (Home Point). The option will be provided to set a new Home Point.
If GPS spoofing is prominent at the mission site, the raw GPS data will be false and therefore unusable. If the vehicle sets the Home Position automatically, it is recommended to reference the Home Point against the vehicle’s actual location before taking off. If the Home Position set by the system does not align with reality, set the Home Position manually as described above.

Takeoff and Transition

Quick Takeoff

Manual Takeoff

If a Quick Takeoff is not preferred, follow these steps for a manual takeoff.

Select Position Mode via the Mode button.

Position mode must be selected for the optical flow sensor to work. The sensor is not available in Altitude mode and will function up to 10 meters above ground level. When the vehicle is higher than 10 meters, it will automatically switch to Altitude mode.

Optical flow sensors provide real-time information about the drone's movement relative to the ground, enabling precise control and stabilization even in challenging environments where GPS signals may be unreliable or unavailable.

While optical flow sensors are versatile and effective in many scenarios, they may not provide reliable navigation or stabilization on surfaces where challenges are present, such as plain and featureless surfaces, highly reflective or transparent surfaces, moving surfaces, extreme lighting conditions, and irregular or unpredictable textures. In such cases, drones may rely on alternative sensors or navigation methods, such as GPS (if available), and IMUs to maintain stability and control.

Press Disarmed at the top of the menu bar.

Arm the vehicle by pressing and holding the confirmation button.

The VTOL motors will spin up. In multirotor mode, the left control stick manages the throttle, regulating the drone's altitude.

Press the left stick upwards to ascend.
Continue the ascent. At approximately 10 meters altitude, the vehicle will switch to Altitude Mode, and the optical flow sensor will no longer be available. The vehicle may start to drift.
Correct the drift with stick input. The right joystick controls the position of the vehicle. Moving this joystick forward, backward, left, or right changes the vehicle's position relative to its current heading.

The left joystick controls the vehicle's altitude and heading. Moving the joystick up will increase the altitude while moving it down will decrease the altitude. Moving the joystick left or right changes the vehicle's heading (yaw).

When a safe transition altitude is reached, transition to fixed-wing mode.

A safe transition altitude should be higher than any nearby object, specifically 15 meters above the highest obstacle in the takeoff area. The transition should be performed into the wind. Use the left stick for yaw control to point the vehicle’s nose into the wind.

Fixed-wing Mode

After the vehicle has transitioned to fixed-wing mode, continue ascending to a safe altitude. Moving the right joystick forward and backward controls the vehicle's altitude. Pull the right joystick backward to increase altitude.

Stay close to reset the vehicle's position based on a nearby landmark, such as a tall tree or something similar.

Or reset the vehicle position based on the camera’s center field of view.

As soon as the vehicle's position has been reset with the Set Position feature, it will switch from Altitude to Position mode.
The vehicle uses inertial navigation with sensors to track the drone's motion and orientation by measuring its acceleration and rotation.
When using inertial navigation, several factors such as wind gusts, turbulence, and magnetic interference can affect the drone's motion and introduce errors in the inertial navigation system.
Consider flying at a higher altitude, as altitude readings depend solely on barometer readings.
Once the vehicle is in Position mode, a Return command can be initiated. Depending on wind speeds, direction, and gusts, the accuracy of the Return can vary significantly.

Landing

Bring the DeltaQuad Evo back toward the Home Point and align the vehicle with its nose into the wind.
When above the landing site press Land.
The DeltaQuad Evo will do a back transition, overshoot, and initiate the landing.

As soon as the Land command has been given, the vehicle will lose its position estimate and go into Land Descent mode.

The optical flow sensor will work as soon as the vehicle is 10 meters above ground.
The DeltaQuad Evo will switch to Position Mode.
When the optical flow sensor is working, let the landing process happen. Do not interfere!

Controlling the Vehicle

This section explains how to control the vehicle in-flight.

During operation, the vehicle can be commanded using the Fly and Flight Tools on the left side of the screen, as well as the Emergency Actions from the top menu bar.

When the vehicle is powered on but still grounded, only a limited number of commands are available. Instead of the Return command, the Takeoff command is available.

It is recommended to practice the following commands in the several times before operating the vehicle.

Return

Return - Quick Takeoff Operation

When the Return command is given, the vehicle will fly in a straight line to the selected approach sectors at its current altitude or ascend to the minimum set return altitude while en route.

The DeltaQuad Evo will place the loiter-down orbit within the selected sectors, descend to the set landing altitude, exit the orbit in the direction of the landing location, transition, and land in multirotor mode at the planned location.

This applies as well if a Return command is initiated by the failsafe system.

Return - Mission Plan execution (no Quick Takeoff)

When executing a mission plan, if the Return command is given by the operator or initiated by the failsafe system, the DeltaQuad Evo will return in a straight line to the planned landing pattern at its current altitude or ascend to the set minimum return altitude while en route.

The advantage of using the planned Landing Pattern is that it ensures a smooth entry into the pre-defined landing sequence and performs the transition and landing into the wind.

After reaching the Land altitude, the vehicle will fly in the planned direction toward the landing location, perform a back transition upon reaching the takeoff location, and land in multirotor mode. This is true whether an Orbit Land Pattern or a Straight Land Pattern has been planned.

In addition to the planned Landing Pattern, the operator can select available approach sectors in the octagon for landing during a Return command. When the Return command is initiated, the red octagon appears around the takeoff location.

If no sectors are selected, the vehicle will follow the planned Landing Pattern.

If at least one sector is selected and confirmed (green), the vehicle will place the loiter-down orbit within the selected sector(s), descend to the set Back Transition altitude, exit the loiter toward the landing location, perform a back transition upon reaching the takeoff location, and land in multirotor mode.

When using the approach sectors instead of the planned Landing Pattern, ensure the Approach Altitude is set 25 meters above the highest object in the landing area.

QuadChute

The QuadChute is a safety feature that triggers an automatic transition from fixed-wing mode to multirotor mode in emergencies.

This typically happens if the vehicle detects a critical issue, such as loss of control, significant deviations from the flight path, or insufficient airspeed to continue safe fixed-wing flight.

When the QuadChute is activated, the DeltaQuad Evo stops flying as a fixed-wing aircraft and switches to multirotor mode, enabling it to hover and safely descend and land at its location.

This feature ensures the vehicle avoids dangerous situations, like crashing or uncontrolled descent, by leveraging its VTOL (Vertical Takeoff and Landing) capability to stabilize and land.

The QuadChute will only engage at altitudes of 300 meters and below. If a critical issue is detected above this altitude, the vehicle will first attempt to descend to 300 meters in fixed-wing mode before engaging the QuadChute.

This feature serves as an essential fail-safe mechanism for maintaining safety, particularly during complex flights or in challenging conditions.

After a QuadChute event occurs, the following guidelines must be followed:

If the vehicle's altitude is below or at the height of obstacles, ascend to a safe altitude by pushing the left joystick forward on the handheld controller.

When a safe altitude is reached, change the vehicle's heading so that its nose faces into the wind by using the left joystick to turn it left or right.

The wind direction can be viewed in the Fly View on the Telemetry Dashboard, indicated by the arrow in the top left corner of the compass.

When the correct heading is reached, use the Transition Command from the Flight Tools menu on the left side of the screen.

After the vehicle has transitioned from multirotor mode to fixed-wing mode, return and land it by either using the planned Landing Pattern, if applicable, or the approach sectors in the Fly View. After the landing thoroughly check the vehicle for damage and fly-worthiness. When in doubt contact [email protected].

Hold

When the Hold command is issued, the vehicle will maintain its current position and altitude. In fixed-wing mode, it will circle the current location with a 100-meter radius.

Strong winds can push and distort the orbit in any direction. Therefore, when issuing the Hold command, it's crucial to ensure there is at least 200 meters of clear space in all directions.

In multirotor mode, the vehicle will hold its current position and altitude. Extra caution is required, as the DeltaQuad Evo's default maximum hover time is limited to 90 seconds. After the timeout, the vehicle will force land at its current location.

Mission

The Mission command becomes available once a mission plan is uploaded to the vehicle. After confirming the mission start, the vehicle will begin or resume the mission from the active waypoint (green). The active waypoint can be changed by clicking on the desired waypoint and confirming the new selection.

After selecting the new waypoint, Hold to Confirm and continue the mission from the selected waypoint.

If a mission plan includes a Landing Pattern, the vehicle will execute the mission and land at the designated location. When using Quick Takeoff, and if a mission plan is uploaded and executed, the vehicle will fly through the waypoints consecutively and orbit at the final waypoint until a new command is received.

The execution of a mission plan can be interrupted using the Hold command and resumed with the Mission command. By selecting a different waypoint as the active waypoint, the mission can be advanced or restarted from an earlier waypoint.

Orbit

Once the vehicle is in fixed-wing mode, the Orbit command can be issued. Click anywhere on the map to select the orbit location.

The green flight path toward the new orbit represents the vehicle's estimated trajectory.

If the new orbit is placed beyond the set Guided Maximum Distance, the following warning will appear.

The Guided Maximum Distance can be changed in AMC Menu -> Settings -> Fly View.

The orbit can be adjusted in location, altitude, direction, and size.

Click and hold the inner white vertex to move the orbit.
Click and hold the outer white vertex to adjust the orbit's radius by dragging it left or right (minimum radius is 100 meters, maximum radius is 2000 meters).
Click on the upper or lower green arrow to change the orbit's direction. By default, it rotates clockwise.

The orbit's altitude can be adjusted using the Altitude Slider on the right side of the screen.

The orbit's altitude is by default referenced to HGT (heights relative to the takeoff location). Special caution should be taken when operating in areas with varying ground elevations.

The altitude frame and the available range of the Altitude Slider can be changed in AMC Menu -> Settings -> Fly View.

Fig 8

Once the vehicle is in fixed-wing mode, the Fig 8 command can be issued. Click anywhere on the map to select the orbit location.

The green flight path toward the Fig 8 represents the vehicle's estimated trajectory.

If the Fig 8 is placed beyond the set Guided Maximum Distance, the following warning will appear.

The Guided Maximum Distance can be changed in AMC Menu -> Settings -> Fly View.

The Fig 8 can be adjusted in location, altitude, direction, and size.

Click and hold the inner white vertex to move the Fig 8.
Click and hold the outer white vertex to adjust the Fig 8’s size and orientation by dragging it in any direction.
Click on the upper or lower green arrow to change the Fig 8’s direction; by default, it rotates clockwise.

The Fig 8`s altitude can be adjusted using the Altitude Slider on the right side of the screen.

The Fig 8`s altitude is by default referenced to HGT (heights relative to the takeoff location). Special caution should be taken when operating in areas with varying ground elevations.

The altitude frame and the available range of the Altitude Slider can be changed in AMC Menu -> Settings -> Fly View.

Orbits generally provide a more efficient and stable flight path for many drone operations compared to the figure-eight pattern. When using an ISR payload with a 180° gimbal, a figure-eight pattern can be beneficial, as the system positions the pattern in such a way that the gimbal never reaches its limits when a Point of Interest (POI) is selected. This is discussed in the dedicated payload sections of this manual.

Change Speed

The Change Speed Command adjusts the vehicle's airspeed and can be executed using the slider on the right side of the screen.

The maximum airspeed of the DeltaQuad Evo is 23 m/s. This airspeed applies during mission execution as well as during operations without a mission plan.

Airspeed vs. Ground Speed

Airspeed refers to the speed of a UAV relative to the surrounding air. Ground speed is the speed of the UAV relative to the ground. Understanding both airspeed and ground speed is essential for effective navigation and flight planning, especially in varying weather conditions.

Changing the airspeed affects battery consumption, so the estimated flight time must be monitored carefully.

Land

The vehicle will land at its current location. If it is in fixed-wing mode, it will first transition back to multirotor mode and then begin its descent until touchdown.

Do not issue the LANDING Command at high altitudes. The multirotor mode consumes up to 12 times more energy compared to the fixed-wing mode. First, reduce altitude in fixed-wing mode and issue the Land Command at 100 meters or below.

Please note that the maximum default hover time is 90 seconds. After the timeout, the vehicle will force-land at its current location.

Transition

The Transition Command toggles between the VTOL modes of the vehicle. When the vehicle is flying in fixed-wing mode, it switches to multirotor mode, and vice versa.

Areo - fixed-wing mode
Transition - transitioning from one VTOL mode to the other VTOL mode
Hover - multirotor mode

Before the Transition Command is issued, the vehicle must be aligned into the wind. At altitudes higher than 100m above ground, or in strong winds, it is not recommended to switch from fixed-wing to multi-rotor mode.

Important Items During a VTOL Mode Change:

Altitude and Positioning
- Ensure the vehicle is at a safe altitude to transition modes without risk of collision or terrain interference.
- Monitor the vehicle’s current position relative to obstacles.
Battery Level
- Check the battery status to ensure there is sufficient power for the transition and subsequent flight.
- Plan for a safe landing if battery levels are critically low.
Flight Mode Confirmation
- Verify that the current mode (VTOL, fixed-wing, or multirotor) is correctly displayed in the control interface.
- Ensure the Transition Command is initiated correctly.
Environmental Conditions
- Assess wind conditions and weather factors that could affect stability during the transition.
- Be aware of any potential changes in the environment that could influence flight performance.
Post-Transition Monitoring
- Continuously monitor the vehicle’s performance after the mode change, including responsiveness and stability.
- Check telemetry data for any anomalies immediately following the transition.

Emergency Actions

LANDING will land the vehicle immediately at its current location. When the vehicle is in fixed-wing mode, it will first transition to multirotor mode and start its descent.

Please note that the maximum default hover time is 90 seconds. After the timeout, the vehicle will force-land at its current location.

SHUTDOWN will stop all motors IMMEDIATELY. This procedure should only be used while the vehicle is on the ground or as a last resort to avoid damage to people or property.

Using this function during flight will crash your vehicle and void your warranty.

MODE

The MODE Indicator displays the current flight mode (VTOL Takeoff, Hold, Altitude, Position, Return, Land, Mission). Select to enable Altitude or Position mode.
