My unit has not been crashed and in perfect working order. Just recently the gimbal has started to act up. When powered on it continues to stutter and jerk every few seconds, yet it is still responsive to the RC by tilting on command. I've included a couple videos in hopes someone might shed some light as how to go about fixing the problem. I have replaced cables, reinstalled firmware and tried a hard reset. The hard reset won't seem to work either, unless i'm doing something wrong. From the instructional videos I've seen the LED should change colors going to an amber. Mine stays red with no change.
