I havent had any real problems... a few times my shock tower bent a little when I rolled it and the body posts broke threw the body when it landed upside down, but nothing a little CA and some pliers could easily fix! I like it alot, only thing was when it came out of the box the camber and toe out was way to over set. I fixed it and it runs alot better, make sure your wheels point straight forward no toe out or the steering becomes sloppy.
