Kixum, I saw a tut for tank treads(two parts) over at < ahref-http://www.cgfocus.com/> cgfocus(Agent Smith from the Bryce Forum recomended the website as something to look through once and a while). I haven't read the tut yet and I don't know if your model uses treads or some kind of antigravity or what but maybe there's something to sort through on treads that might help if you are using treads on the tank. - TJ
