Panther F; I bought, built and am currently running these in my KT. I got tired of the Impact trans stripping gears in an hour or so of combat. My KT tips the scale at almost 17lbs. The Mr Gearboxes have been a God send. They have ten times the hours then the Impacts with out any problems, they have way more torque and run a great scale speed. For the money I would say you get what you pay for. I am currently looking into ones for my Panther D build which is on hold at the moment. So as you can see I would not hesitate to purchase them again. They were fun to build!!!
