You could win races with the RTR, BUT since you're planning on racing I would look into getting the roller instead and maybe scoring on a used radio (the RTR radio is pretty good, the throttle servo is a POS tho) to cut costs. I was also suckered into getting an RTR but face it, this sport is dammed expensive so that money you saved getting the RTR is going to cost you alot more in the long run if you plan on racing. (especially since it sounds like you're planning on replacing parts) RTR's are mostly for "bashers" who just want to have fun. Funny thing is that bashers really need the most durable equipment, and the race roller is more durable. Then again if you're unsure about this sport, then RTR might be a good "trial" truck.
