I wonder what your battery pack is. If it is a 5 cell nickle metal Hydride (NiMH) pack it should be well over 6 volts. I find they will charge up to over 7 volts. I think an old battery (or in your case maybe 2 old batteries) with a dying cell can cause this sort of uncontrolled rotation on an RMG winch. If you have failsafe turned on, the winch will draw power and the voltage will drop into the failsafe zone and the winch rotates/sheets to a little tighter than half way out, then the voltage can go back up and the winch rotates with no input from the radio. I think this can happen over and over.
I think this is a specific problem that generally happens under load, but you might make sure that you have a good fairly new battery (with no dying cell).
If you are using a 4 cell MiMH pack then I believe 6 volts would be a good full charge number and if the winch has been set up to run on 6 volts then it will be happy and not go into failsafe at that low voltage. My point being that the RMG is set up (per the instructions) to run on X volts and it might act badly if you decide to use a lower voltage battery pack, like 4 cell instead of 5 cell.
