Sensor calibration
In order to perform the sensor calibration, select the Vehicle Setup tab and choose the Sensors menu.
If you use the flight controller COEX Pix, and it's installed with servo pins faced backwards, all Autopilot Orientation columns must specify
ROTATION_ROLL_180_YAW_90, otherwise the flight controller will not correctly perceive the tilt and rotation of the copter.
Compass

- Choose the flight controller orientation (ROTATION_NONE if the arrow on the flight controller is aligned with the arrow on the frame).
- Press OK.
- Put the drone in one of the orientations marked by the red outline and wait for the appropriate outline to turn yellow.
