I lifted off my x-star premium near a house with a metal roof. Didn't know too much about magnetic interference. The drone ended up crashing from 40 feet up, and flew down and hit the ground at 20+- MPH. Camera fell off. Was fine. So is the gimbal. Drone hit the ground, seems the props took most of the G-force. I put everything back together... it worked.. talked to tech support. Figured out MI was responsible. Now it's flying fine. How the hell is it okay? Any Phantom I would of driven before would of been destroyed.
