# DeltaQuad Evo maintenance kit
The following section describes the components of the maintenance kit, their installation, and the benefits of using them for optimal performance.
{% hint style="warning" %}
**Scheduled Replacement of DeltaQuad Evo Maintenance Kit Components**
To maintain the peak performance and reliability of your DeltaQuad Evo, it is crucial to adhere to scheduled maintenance practices, including the replacement of the components from the maintenance kit. Due to the nature of their design and usage, components such as VTOL arms, the pusher motor pod, the wingtips, and propellers incorporate moving parts and utilize lubricants for optimal function.
After approximately 12 months, these components may experience wear and tear, and the lubricants used within them can begin to dry out. This can affect the overall performance and lifespan of the drone if not addressed proactively. Therefore, it is recommended to replace these components with new ones provided in a DeltaQuad Evo maintenance kit.
By replacing these parts at the recommended interval, you ensure that your drone continues to operate at its best, maintaining flight stability, efficiency, and longevity. This proactive approach to maintenance helps mitigate potential issues before they impact your drone's performance during missions.

The DeltaQuad Evo maintenance kit includes the following components:
**VTOL Arms**
The kit includes four VTOL arms:
* **Two VTOL arms with clockwise rotating motors and propellers**
* **Two VTOL arms with counter-clockwise rotating motors and propellers**
These VTOL arms come pre-assembled with landing gear, ESC (Electronic Speed Controller), motors, and propellers balanced by DeltaQuad to achieve the lowest vibration profile, ensuring smooth and stable flight performance.
**Pusher Motor Pod**
A fully assembled pusher motor pod is included in the kit. This pod comes with:
* **A housing for the ESC, motor, and propeller**
Pre-installed and balanced for optimal thrust and minimal vibration, the pusher motor pod provides the forward propulsion necessary for fixed-wing flight. It complements the VTOL arms' vertical lift, aiding during both ascent and descent by holding the vehicle's position.
**Wingtips**
The maintenance kit also contains a pair of interchangeable wingtips. Each wingtip includes:
* **One servo** **for precise control of the drone's elevon**
* **One LED for enhanced visibility and status indication**
The wingtips are designed to be easily attachable and interchangeable, allowing for quick replacements or repairs. Either wingtip fits on both sides of the drone.

**Pre-installed and Balanced Propellers**
It is important not to remove the installed propellers, as this would negate their pre-installed and balanced state, designed to achieve the lowest vibration profile.
All propellers in the kit are pre-installed on their respective motors and balanced by DeltaQuad. This balancing process minimizes vibration, crucial for maintaining flight stability and extending the lifespan of both the motors and the drone's structural components.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.deltaquad.com/evo/maintenance/deltaquad-evo-maintenance-kit.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
