Well, that Revo center diff idea didn't work out too well. The 28t gear on it was too small for what I was going to use it for.
So, I created a semi-transmission that has a slipper clutch and a center diff together, for the ultimate in light-weight and tunability. Basically, it's my version of Mike's Slipperential, except I won't call it that because that's his name for it :027:. It mounts where the old tranny went, so it doesn't take up any extra space. The motor is a Feigao 540C 7XL. For gears, there's a Kyosho 44t plastic spur on a Hyper 7 diff, an 18t mod1 pinion on the slipper clutch shaft, a 40t Revo spur gear on the Revo slipper clutch (the slipper shaft is also from a Revo), and a 20t pinion on the motor. Here's a couple pics:

I will have to get an E-Maxx or Revo output shaft and cut it down, so I can modify it and use it as the output for the center diff.
The batteries for this will be 5s2p A123 cells, taken from a Dewalt 36V pack. I will charge the battery as 10s1p on an Astroflight 109 as 9s Lipo at the highest current it will charge the pack at.
So far, I'm not sure how the I will mount the batteries. Either both packs will be on the left side, or they will be split with one on each side. Any opinions on this would be great.

Sorry about the width of the truck, those are IMEX Romulin offset wheels (17mm Savage X hexes were used for the 17mm wheels). It looks like a square even though it's as long as they get - extended chassis (3Racing) and extended wheelbase arms.
