ArduPilot FC Alignment Viewer

Drone frame (forward arrow) Flight controller (rotate this)

Drag to orbit • Wheel to zoom

Rotate the flight controller

Use the sliders/buttons to match how you physically mounted the FC. The angles shown above are the values you can enter in ArduPilot custom rotation parameters.

Roll (forward axis)

Right wing down is +roll

Pitch (right axis)

Nose up is +pitch

Yaw (up axis)

Turn right is +yaw

Notes

The FC arrow should point the same direction as the drone’s forward arrow when correctly aligned.
This tool shows a custom rotation in degrees. In ArduPilot, set AHRS_ORIENTATION to Custom and enter the shown AHRS_CUSTOM_* values.
If your results look “backwards”, flip the sign on the axis that feels inverted for your setup.
