do what you want with your X-Mods, but I knew a dude with a 9v, we drove it about 30 times...and that was all the little motor could handle, and about time 31, the car suddenly stopped and white smoke rose, the 9v blew the bejeezus out of the motor, im staying away from powere mods like that. im all for mini-z bodies and things but after seeing that im staying away from dangerous power mods.
