I would have to say that this will be more than sufficient. We ran a van door motor with no additional reduction and were able to lower the competition bridge relatively easily. See my other post in this thread for details of our set-up - I just caution you to be sure your arm and mounting methods are sturdy enough and not likely to bend/deform in any way while trying to push down a bridge in a match (which we had happen to us twice).
