Last time I have problems with IMU & Compass too often. Drone, after turned on, always showing an IMU error for 2-3 minutes and then error is going out and saying all are fine. I have calibrated it on ideal surface with 0/0 degress and not helped. Compass are also saying that I have too high electro-magnet area too often. I am calibrating it for 5-10 times in different areas to get it calibrated before each flight. Maybe because I am in mountains? Any suggestions?

BTW - I did a video, and looks like it is working right with all these errors:



Cabo Girão is a lofty sea cliff located along the southern coast of the island of Madeira, in the Portuguese archipelago of Madeira. Cabo Girão is a popular lookout point, especially after a glass-floored viewing platform was installed in October 2012.
