Ok thanks for your reply. But the values are the same on the craft outside on the field. Loiter and rtl are ok when i calibrate with live calibration. But when i power of the craft or change the accu loiter is wrong. The values are saved in the parameter list. But i must calibrate every flight. The values are then the same but i must du this.
Hi Thomas, i always thought that compass calibration was a process that depended greatly on subtle magnetic forces from the earth and should not be performed indoors. The electronic devices you have close by will likely affect your calibration.
I have calibrated mine manually a couple of times before but both times were with the APM unit mounted on the craft , outside ,using a laptop and when i did not notice much difference in performance from the auto calibration feature that the mission planner has.

I test the simple mode tomorrow. When i full throttle at the flight the craft yaw. Is this because the compass ?
