[I just purchased a traxxas e revo model 5603 electric car at the tune of 950.00 dollars. I have had it for two weeks and the speed control gave out. Now I have to send the car in for the warranty. You can not just send the part you must send the entire care in at a price of 39.95. I tried to get them to send me a new one but they would not. Just for you to be aware. If it quits and dose nothing it is the speed control that is for sure.
