I believe I did exactly as you said, it ran fast and as soon as it got extremely hot it stopped moving as quick as it once did. So I believe its in order for a rebuild. At my LHS the motor cost 24.95, would it be cheaper to buy a new motor or rebuild it? I know nothing about rebuilding motors. I just recently got into the sport about 6 months ago. I always drove them before but never started rebuilding stuff till recently. Also, with the brushless systems I was thinking about buying the Castle Creations Sidewinder V2, is this a good setup for my car? If not, id like to know before I shed out $160 for it.
