Sorry, all I can really say is that it's a major company and it uses a clutch like the Revo. If you come out to race you may catch a glimpse, there's one this Saturday and I'll (hopefully) be out there. So far there's been 2 races for the WPS and I've taken 1st both times in MT. The classes are buggy, truggy, MT, and tenth scale electric. Where did you tell me you were located again? It can't be too much of a drive
