I was flying my P3 a couple days ago and flew it up 334 feet. I started to descend and I took almost 2 minutes to get back, close to the ground. I was trying to lower it pretty quickly but I was scared if I lowered it to quickly it would start to go out of control or I would accidentally disarm the motors mid flight. As I was lowering it, it started to rock side to side a little bit. Should I be worried about lowering too quickly? Also, can you accidentally disarm the motors in flight and have the Phantom drop out of the sky like a brick?
