response tires are some good tires, but they have a very soft sidewall and do wear really fast. Pythons are a nice alternative. Heavier but last longer and do a good job on the track.

I'd follow Mich's advise and do the things he listed along with some P2 rockers and pushrods. Pick up the full line of traxxas CB's and spurs so you can re-gear according to the track your running on. Other than the small option parts, the Revo is pretty much track worthy.

Good luck on your Star wars theme project. May the force be with you young Jedi......=)
