My son has a Midnight Pumpkin running a 15t motor. No problems mechanically, he's broken the body a few times which is easily repaired using poly cement. The body posts and the little springs on the suspension (not the shocks) are the only weak points we've found. There is a number of easy mods for the springs and Hot Racing have started making aluminium body posts again. I will say that my son drives hard so you may not have any problem with the body posts, but the springs will break at some point. Other than that fit bearings and they're pretty tough.
