I put these bodies throught the ringer. Including running my booster car at the street dreams 2 car event in Detroit from 8am to midnight for two days (lotsa bumping and banging, racing). Also hit lotsa stuff. THe bodies stay on well. Unfortunately the booster car lost a coil for my steering after 6 months of major abuse and Im now enjoying my new WRX car I got from Tiny rc.com (fast shipping by the way).
The painting and cutting process......The cutting takes no real time at all. The painting process can be brutal if you are a perfectionist. If not it can take like no time at all, but it will look it. I myself am not a painter, but they turned out ok. Mind you my test cars are now pretty beat up from concrete scrapes ect ect. But they all still fit and stay on and even look ok (if a little tired). SO in a nutshell the paint will look as good as you paint it, they hold up great and cut in no time.
GEt a bunch of friends to pitch in and a sheet of 8 cars wil cost you next to nuthin. And the paint adds almost no weight and yes its like running with no body.
