Mount and Orient Controller

Pixhack V2/V3/V3X should be mounted on the frame using vibration-damping foam pads (included in the kit). It should be positioned as close to your vehicle’s center of gravity as possible, oriented top-side up with the arrow pointing towards the front of the vehicle.

If the controller cannot be mounted in the recommended/default orientation (e.g. due to space constraints) you will need to configure the autopilot software with the orientation that you actually used: Flight Controller Orientation.
