I tend to break the rear bearing carriers, and the front c-hubs but once those have been upgraded the truck is NEARLY indestructible.

but: I run an rpm bumper, and I just ordered a set of rpm arms for it. I cracked a rear arm but I guess you could say I abuse my rusty. thats the main reason I love my rustler is you can beat it then it will only cost you $5 to fix it.
