Buy turning with a wrench, you might not be getting the answer you
think.
Generally there will be a safety clutch between the shaft of the motor
and the
capstan. So if you turn the shaft and the ailerons have hit their
stop, you will
be slipping the clutch.

So you need to see if the cables move relative to the capstan.

Bill, in this case I could see the capstan slipping under the cable.
Evidently the cable could slip on the capstan easier than the capstan could
slip on the clutch.
