this forum is more deserted than a dairy queen. like a tumble weed strolling across a old western town or something. or like a grandmas pu$$y
you get the point i guess
its not deserted just not everyone has an answer and usually refrain from posting unless they know for sure.
The slash 4x4 should take a couple of good whacks without breaking. If you break something buy RPM replacement parts those parts can take massive abuse.
If you want one of the ultimate trucks(savage flux) that can take massive abuse you would have to double your budget, and then some (not counting batteries) But even then that will break eventually too if you hit em just right.
