another problem with my Pixhawk which never occurred with any of my APMs:
I cannot calibrate the accelerometer. I have a continuous drift in all directions in the HUD/FlightData of Mission planner.
thanks a lot! I must have overlooked the other discussion.
It explains (but does not really solve!) both of my problems (Compass and HUD).
Strange that there is no note/hint about that in the Wiki or somewhere…
