# Motor Spin Direction
The motor spin direction can be changed using DShot commands on PX4, Ardupilot and Betaflight.
## PX4
Motor configuration is done using the Actuators tab in [QGroundControl](https://qgroundcontrol.com/).
Select DShot protocol for your motors\
\
Configure the direction in the Geometry tab. This tells PX4 the direction the motors will spin.\
Use the "Set Spin Direction" buttons to change the spin direction for each motor. You can lightly touch each motor to ensure the spin direction matches the geometry you selected above.\
\
***
## Betaflight
Connect your board using the [betaflight configurator](https://app.betaflight.com/).\
\
Navigate to the Motors tab. Select Motor direction and follow the prompts.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.arkelectron.com/products/electronic-speed-controller/ark-4in1-esc/motor-spin-direction.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
