I have had a couple of times where I wanted to descend quickly and the copter got quite wobbly so I had to slow down. But yesterday, while descending the copter just went nuts, pitching and dropping quickly despite trying to send it up. It crashed and broke the legs off. This is real spooky. I have a 2w 2.4 booster on the remote and a 2w booster on the FPV. Can they get tangled up? Not sure what to do. The copter seems fine now.
