First off, no pics yet, sorry! But, it won't take long because I'm already done the build, prototype anyway. Remaking some parts and strengthening others still to be done.
A basic overview of how I went about it-
Took apart my Revo to rob its motor (9XL), speed control (MM), esc mount, battery (TrueRC 4S1P 5000), battery tray, and the Elektri-clutch. Yeah, that's right, it has a clutch.

I also use a RCM Revo motor mount putting it behind the rx box. I cut down the mount so it would sit lower on the chassis. I also flipped the center diff and cut out another slot to fit the spur. The brake servo is now part way in the rx box (had to make room for the motor) and is a push/pull setup keeping the adjustable bias. The MM is behind the battery across from the motor. I'm running the 18T clutchbell out of my Revo as well, seemed to work pretty well up and down my alley, no wheelies though, but it didnt slouch either, just grabbed and went. With a smaller bell wheelies would be possible but right now this feels awesome and will probably do better on the track.
