I have a T-Maxx 3.3 that is broke in and has a couple of hours on it. I already have two pads missing on the slipper clutch and have a replacement and spare. The guy at the local RC shop said that it was adjusted to loose from the factory. I didn't know to check it. Now I do. What other parts would be good to have on hand? I know these thing will break parts. I just want to know what the common parts needed are. This truck is a load of fun.
