The other day was flying my Mavic. Before takeoff there was no indication of a need for a compass calibration. During the flight, I was approximately 3000 ft away when I got an indication on the iphone screen of a compass error. I hit RTH and nothing happened. After having a flyaway loss with a Phanton 2, my heart stopped beating for a moment. I still had an image on my phone and could see what the camera was seeing but no response from the Mavic. About 30 long seconds later, the compass error disappeared and it did return home. Why would a compass error occur 400 ft up over a wooded area and why would it not have returned home since it was still showing GPS mode?
Thanks for any insight you may have.
