RE: suspension question(is this a new type??)
in fact, i dont see that this is going to give as many degrees as solid axles, due to the fact that the movement of the gearbox is a fraction of the movement of the wheels... what im putting forwards is something with as much travel in the wheels as crawlers, but with additional ground clearance, and possibly a way to compensate for the increased center of gravity
also, i know it might sound slightly controversial, it has several additional tuning options... the cantilever leverage, and the link mounting positions.... the same truck could be switched from a basher to a crawler, by doing something as routine as changing your shock positions and wheels...
