It's a t-maxx. We were thinking about making it a .21 but we didn't want to destroy the diffs and tranny. We did put an rrp foc in it. But we put a trx. 15. pro (2.5 wasn't available for exchange yet) and put a 16 tooth clutchbell on it. We made it strickly for hill climbing. I forget the length of it but i believe its close to 2 feet long.
To get it to be true 6 wheel drive my neighbor bought to aluminum differential cases and cut them at work and then welded the sides together then put all the stuff in it and bolted it together. Theres another output shaft coming out the other side connected to a drivecup. We then got a old driveshaft and switched the end so it was like a tranny driveshaft. Bolted it to the very rear diff and now we got 6x6.
We are running the proline suspension with traxxas big bore shocks, 1 set of aluminum bulkheads, 2 aluminum shock towers, All steel driveshafts, and we are running the beast with Ofna Monster Pirate rims and tires. We will soon make it 6x6x4 if we think the turning radius is horible to control. I'm sure I'm forgetting stuff. I'll try to get those pictures by wednesday.
