Do all of the traxxas stampedes break all the time?

If your stock Traxxas parts on the Stampede aren't holding up to your regular driving style, take a look at the RPM replacement parts. They make hub carriers, arms, and beefier custom molded parts for that truck that might hold up better over time. If you've burned up the motor you might have your slipper clutch locked down too tightly. The ideal setting for the slipper is lock down then back-off about 3/4 to 1 full turn to allow the slipper to do its job. If your body is cracking too much, there was a good article by David Baker this month in RC Driver about using drywall wall patch and silicon compound to repair the cracks. That or even a bit of fiberglass would get your body back in shape and last quite a while. Hope it helps!
