I finally got the CRT put together. It came with the RC-Monster mount and the battery tray so there wasn't much to do to get it up and running.
Only thing I had to do to get the 1717 to fit was make a spacer for the center diff as seen in the last pic.
Electronics.......Mamba Monster with the CC 1717 1580KV motor
The gearing......46/19T
Batteries..........6S2P A123
I plan on playing around with it in the truggy form for a little bit and then it will become an On-road beast
