MFD, it is 1.15, but what is "the interface of the motor"? Is it about magnetic fields and interference? Anyway I will double check the AP mounting setting.
Yes, you should use Joystick calibration after you have trimmed the plane. No need for common calibration.

Yes, the Motor, ESC or its cables near by AP can generate a lot of electromagnetic interference however you can test with the AP outside the plane, to rule out if the compass problem comes from EMI or it is not calibrated corectly. Remember The calibration should be donr on all three axes.

Hello,
Regarding calibrating the compass on all 3 axis..


1. ----While the AP is in Compass Calibration Mode should we rotate the aircraft 360 on horizontal , vertical and diagonal axis?

2-------.And should all three axis be calibrated at the same time? or 3 separate calibrations?

Yes it's something about "magnetic fields" of the motor.

Have you trimmed the plane after "Common CAL."?
If so, you need to Calibrate JoyStick again.

We don't recommand to execute "Common CAL." in the field often. First you need to make sure the AP has warmed up, and you need to make sure the plane is not shaking by the wind...etc.
If the plane flies well in MAN and STB mode, only "CAL. JotyStick" should help.
