I calibrate everytime my compass when I start a new flight. Also on the same location. But do I need to do that on my phantom 2? Because if I startup my phantom 2 it is flashing orange. Mostly I calibrate my compass. Or do I need to wait for the gps stuff. After the compass calibration my gps saves home location. Does it do also before the calibration? EDIT: posted in the wrong forum. It has to be: Phantom 2 Discussion.
