I can't take all the credit for it. I bought it from rchippie back in January and he had done the conversion on it. I just had to install the MMM, 6.5mm connectors on the motor and put in the Rx.
Very nice! I just bought a crt of ebay. I am going to be running a neu 1515 1y with the monster max like you, but with 4s 8000mAh packs. I'll be geared 14:62 though.
