I have a Rustler with the 5700. I normally run 7 cells geared 87/15. It's a blast. The one thing I ended up doing was moving my receiver to the front of the truck away from the motor ESC because I had some glitching on slow starts. This totally solved the problem. Other than that all I can say is you will probably want to invest in a wheelie bar and an aluminum idler. Down the road the FLM tranny case is a nice option to make the tranny a bit more hardy.
