I took an old Chassi From my Redcat and wacked off the rear just in front of the motor holes, flipped it around and drilled holes in bolth chassis and bolted them together. the angles and distance has to be perfect, but i never ever have to be worried about breaking my nose again the drive is snug an safe. You have to use the old plastic piece on top of the wacked off piece but i love it is is stout as a brick house man. And with my suspension upgrade from big bore stubbies to rear Avalanche XP Shocks i have created the ultimate RC, Along with my Differential Upgade The only thing i have to worry about is Fuel. see my upgrades at<>www.catbob07.rcuniverse,com <> If you dare. I know i did.
