I was flying my drone above the tree line in a park when all of a sudden the drone fell out the sky. I'm not sure if it hit a bird or the blade just detached itself but when I found it one of its blades was missing. The thing was flying one second then next second its in a tree. Fortunately there wasn't too much damage and so far I thought only the roll arm needed replacing but after replacing that then turning it on for the first time the tilt motor doesn't seem to be working. Here's a link to demonstrate the problem Imgur: The most awesome images on the Internet Anyone know of any fix?
