I'am to convert mine, near to be done. I've take the RCM motor mount for the revo, fit very nice.
I've a Neu 1515 1Y motor with flightpower EVO25 5000mAh, 4s li-po and MGM compro 16018 controller.
I've a 12 pinion, and i've change the stock buggy wheel and tire for monster truck size tire. I've put Ofna half offset wheel and badland MT tire.

Little "bizare" look but it's a nice machine.
