OK good. Briand, do you have stock diff in your revo???
And for the tranny gear, that's what i'am think, keep the plastic is much easier to work with.
And for the tranny, i don't want to have reverse, and my first goal is to keep the mechanical break, because i don't want to pull current from the batteries for breaking.

For the 9XL motor with the RCM heatsink, does the wires of the motor clear the rear upper suspension arm????
