I crashed my drone. I bent the gimble arm. Initially after the crash the drone would start however the camera was flicking around because of the bent gimble arm. The situation has changed now it will not start at all. I read a forum post where the gimble arm & camera was removed the base plate put back on 3 ribbons in the plugs & you can still fly. I have done this but the drone will still not start up. If I hold the battery button down for longer than 2 seconds the 4 green lights stay on the button red light blinks red doe approx 8 seconds then goes out - no start up. Can anybody pls assist??
