LOL...Ya i just tried my 3.0 motor in it and put some elastic bands on the tire for traction and it can wheelie....But the 4 cat wire...wow what a diffence in rang went from about 8 feet to probally 18...it's great....I don't have a cat so I don't have to worry ....It pritty fast too..One of the tires isn't on straight so im getting some wobble so im not getting my full speed...But I will keep adding to this...well hopefully....!!! My wife couldn't believe I was up late doing this...women just don't understand!!!! Except the one's that are on this forum
