I'm rebuilding ours from the ground up right now. Baught new at the end of July, not used that much, and its now pretty much a pile of crap from bumper to bumper. Its my wife's and I wanted to get her a real race truggy but she likes her revo so I'm for some reason putting a ton of new parts and money into it. Her driving style doesn't help much either. She drives it like its bombproof and its not. I'm 75% done with rebuilding it but I don't even know if you can call it a rebuild. Its about 90% all new. It does look pretty badass but I'm sure that will only last about 1 or 2 heats.
