RE: Unlimited MT class
If you want the only out of the box race ready unlimited truck, it would be the bergonzoni MT. It's a basic buggy kit with the addition of the proper gearing, MT tires and wheels, body mounts, and a pre painted Atomik truck body. Not only is it a killer race truck, it's also the only rc car i know of with a lifetime warranty on the diffs. I've been fooling with these trucks for a couple of years now and they are still the best flat chassis truck I've seen on the track. If you are interested in one I've got a couple of good used rollers, a built kit that's never been run, and a complete in the box kit.
