I have the Zenmuse H3-3D GoPro Gimbal on my Phantom 2. Recently it has developed an intermittent problem of jerking to one side or the other for about 1-2 seconds, then resetting back to the normal position. It usually does this when I'm beginning a slow turn. It has not been through a crash or hard landing. Does anyone out there have an idea of what's going on and what I can do to fix the problem?
