e-maxx ext. flm chassis single motor set-up

[thebubba]

Trying to get lay of the land, so I thought I would get a couple of post out and try to get some help. Am trying to build all alum. e-maxx on ext. flm chassis, and want to go direct drive with slipperential. I've heard rc monster makes a single motor set up for this chassis, but can't find on their site. Any info. or help would be muchly appreciated. Thanks!!!
