During Transition

The following should be monitored when the vehicle transitions from vertical flight to horizontal flight.

After reaching transition altitude, the vehicle will commence the transition to fixed-wing flight. The pusher motor will engage 5 meters below the target altitude (switching from quadcopter to fixed-wing). It will transition in the direction planned for takeoff, but wind can affect the direction, especially if the vehicle is not positioned with its nose directly into the wind.

The vehicle will engage high thrust using its pusher motor until it reaches the target airspeed. After this period, it should navigate towards the hold pattern or first waypoint.

If any malfunction occurs with the airspeed sensor, the vehicle will abort the transition after a timeout of 25 seconds. During this period, the vehicle can cover a long distance at the transition altitude. LAND mode must be engaged before the vehicle is at risk of colliding with any obstacles.

No Forward Motion

Operator Action: LAND

If the vehicle is not moving forward or is drifting with the wind and does not seem to transition towards fixed-wing, there is likely a problem with the pusher motor or propeller. The operator should review the propeller configuration as described in the manual.

Flying Backward

Operator Action: LAND

If the vehicle starts flying backward with increasing speed, the pusher propeller is likely mounted in the wrong direction. The transition should be aborted, and the pusher motor should be inspected.
