I have a stock e-maxx and would like it to go faster. My friend has a t-maxx and I would like to keep up. What is the best way to do that and to have the same reliability as a stock e-maxx? I don't want to put in big motors if they are only going to give me 10 runs. I don't want to put in parts if there not going to last as long as the stock parts. Please help.
