[BP-Revo]

My opinion is covert the Revo and use either a Neu or Lehner motor with a Quark or MM ESC. I'd say a Quark with a Lehner 1940. If you want to do a little custom work, keep the stock Revo transmission (just put in a FOC and get the Close Ratio two speed) and then gear it so first gear covers just about every type of driving except high speed passes (or the whole track except the straight). Then, you can run the disc brake still, and be able to use a center diff and rear brakes as well.
