i would totally just suggest you get a new e-maxx 3905 roller(not electronics) or a e-revo roller i see them go on ebay for 110 ive also seen a 3905 e-maxx roller go for 70. just pay attention to ebay and at the bottom of the front rctech page scroll down and look for the wanted adds. and post new thread for wanting e-maxx roller or something like that. that is probably going to be the best and easiest way of doing it. sounds like the car you have needs a lot of work.
