I'd appreciate a better set of eyes on this. Which motor is failing here (this is a 3DR X-4)? It looks to me like it is back-left - Ch2, since the copter rolls left and pitches up. But physically back-right - Ch4 - seems much more likely since the motor does not turn smoothly and is pretty hot on landing. Also is this likely to be motor failure, esc failure or de-sync? As you can see the copter recovers, but its somewhat worrying which you are 300ft up with go-pro and gimbal attached.
Thanks in advance for any words of wisdom.
