I removed the hardened gears from the Hot Bodies center diff and installed them into the Kyosho cup. I also went with 20K center diff oil but it will still wheelie on demand. I can flip my truggy if I want to. I'm also running a plastic 46T kyosho spur now with a 15T pinion.
I also flipped around the motor wires.
