Yeah, maxamps are waaaaaay overrated. They stretch the boundaries of just about everything in their products. Unfortunately, the worst place they stretch is your wallet. You can get a battery with specs equal to, and usually better, for about 1/3 what you paid for your maxamps. That's why it tends to be new/uninformed users that buy them. Once you learn more about what is out there, you don't make the mistake again...

As far as getting you back up and running, if you cracked the rear bulkheads, order stock bulkheads to replace them. If you broke the chassis, ditto on the chassis. Replace the arms with RPM if they are broken. Replace the stock Revo shafts with stock traxxas Summit shafts. If those aren't broken, run them til they break, they are fine. Replace them after that with the Summit shafts.

Install a rear chassis brace to stiffen the rear chassis for jumping. There are a lot of threads about that mod on here as well as in the E-Revo Brushless forum at Traxxas.com.

Did we miss any parts, or did that cover your breakages?
