Sensor calibration

In order to perform the sensor calibration, select the Vehicle Setup tab and choose the Sensors menu.

WARNING

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.
