[Eduardo lavratti]

have you check if magnetometer are working ?
You can see the magnetometer values in messages window after change the telemetry to raw_sensors or scaled sensors.

if its working, have you calibrated the magnetometer ?

About servo movement when in AUTO2, its normal when the gps are locked and the plane stay stoped.

Anyone know why and how to fix it.
