Yeah, but thats why I think this could be shrunk....it's a simple design. Plus for my application, the one I have is perfect. It's about 3 lbs, and since I guess technically my truck is larger than most of the 1/4 scales, it fits without too much of a problem. I tried a search for the other reverse that fits the zenoahs, but came up empty.

I was originally going to put the brakes on the axles for more realism, but decided to go this route and place a single (but tough) brake off this tranny.
