Hey guys, one of my old coworkers brought this in to work today. Can't get much out of him about it. I think it's an rc10 500 but I don't know. The Belt system is really wicked on this thing. Really tight too... Well everything is pretty wicked actually. And I believe all the 500's I've seen online were only 2wd...?? I just figured maybe someone could chime in that knows this chassis. And maybe if it's worth anything... Thanks in advance guys!
