I have been trying to figure out how to put an independent suspension on a Huge scale RC. What I have noticed on large cars is that unlike small RC cars the rod going from the dif to the wheels is solid and can't extend/shrink. Why doesn't this bind up?
I have also noticed that for some reason they don't line the suspension up to move exactly up and down. The wheel's pitch is actually set up to change as the suspension depresses.
