I have several questions that I hope some of you can answer. How many runs can a graphite car make before it starts to decline speed-wise? Same question for an oil car. Do you guys who are in the racing league recycle your axles, wheels, and bodies? If so, how many races do you expect to get out of each (wheels, axles). I guess I am wondering if you have to buy new stuff every single time. I am interested in the racing league, but not sure how often I'd be able to change components out.
