I have only about a gallon ran through my tt and it's been an awsome driving experiance. I have faced the weak shock shafts and a head bolt disaster but this is still by far the best rc experiance for me. The head bolt issue was builder error. I reused head bolts! The TT handles better to me than my truggy I use to have. Once you get all of the little bugs gone it is truely a beast. I always try to find buget priced rc's and with the money I save build the shit out of them. The rampage tt is the perfect project! Build and let it be built!
