RE: rustler
How hard are you going to drive it?
If you are looking for a good truck to start out with in the nitro or electric scene, it is possibly one of the best ways to go, IMO. I myself started with one and it taught me alot about RC and tuning. Traxxas stands behind their vehicals and their products and most hobby shops will carry what you need in stock for that truck, when things do break.
Afterall, the truck isn't bullet proof. It will break from time to time, but it is fairly strong that is for sure.
