I went with t-maxx style aluminum clutch and did the maxx wheel mod... truck will do backflips with the os 18 engine.. you should be able to do some wheelies with the stock engine however, but i can't confirm this.. the biggest problem is lack of traction and clutch engagment.... the alum clutch helps alot and the pin tires just hook up... try running in grass, it helps for traction...Be careful and keep an eye on the diff cups and dogbones, as the repeated pounding will break parts... there are several mods to help with this... just search this site for help....
