Me and my friend were are a RC field at our local state park last Sunday. My friends P2 dropped out of the air. Luckily he wasn't too high. 20 - 30 feet. It landed on the tall grass below. It did ruin the landing gear, they will have to be replaced. no other damage. We were able to start it back up. Although we didn't fly it after that. As I was watching him fly his P2, I did notice he was making some quick stops and such. Really putting it to the test, Anyways, The motor stopped, I believe the lights also went out and it dropped to the ground. When it hit the ground I, at first, thought it instantly broke in two, but actually as soon as it hit the battery popped out. We ran over He picked up his P2 and I picked up the battery, it was still on, weird. I turned it off. Anyways, has anyone heard or has it happen to you, that the battery became loose enough in flight for it to lose power and crash? Any other reason for this to happen? He thought he may have shut it off in mid air, as in both sticks down and in. I don't think that is possible.... is it?
