If you guys want to check it out, here is the conversion that I did. It was asked somewere how the mechanical brakes will work, and this is what I did. I got a 3 channel radio that has a mixing feature. This allows the 3rd channel to be mixed with the throttle channel and have independent adjustment. I put 500000 wt oil in the center diff and use one brake pad only. I don't race, so I don't know how it would do on the track, but I can say that it runs and brakes well for bashing.
