Traxxas doesn't offer a kit - they only do rtrs. If you wanted to though you prob could pick up the parts on Ebay and build one. I did that with a Tmaxx, it was fun, but expensive. Prob be better with an rtr, drive it for a while then if you're going to stay with it, do some mods and or add some hopups o change it the way you want.

Before you buy, look around to see whats out there in the way of aftermarket hop ups and mods. Go to towerhobbies.com and search on the car you're interested in - that will give you some idea whats available.
