Seen the first two links; the last one’s kinda useful, but as I’m only pivoting the front driver set, that part won’t help me. I’ve got a pretty good idea for the pivot (I hope).
I’ll also likely only power the back drivers–I only have one motor/gearbox. As it is, I only have 20 or so cars, so that shouldn’t be a problem.
I have plans drawn for the rear frame (main frame is cut, need to cut the wheel slots and other holes) and I’ll start work on the front frame after my first midterms this week.
