: If you need to _slow_down_ the back drive, you can use the brake setting on the Victor. This puts a short across the terminals of the motor, which is acting as a generator in backdrive. The short makes it hard to backdrive, but hanging (last year's sport) a robot with a van door motor with the Victor on brake is not guaranteed, because at slow speed, the generator isn't generating enough voltage to stop itself, just remain slow.

We used a winch with the two van door motors in last year's competition to hang, and with the brake mode on for the speed controllers, it was enough to keep our robot in the air...
