Re: 6wd - chain path revisited

For the last 2-3 years, 330 has used the middle design. We don't use tensioners very much; last year the potentiometer mount served as a tensioner on the gearbox-to-center chain. We used #35 and figured out exactly where to place the wheels to eliminate tensioners. The big advantage is that a single thrown chain can't do a whole lot to you, unless it's the gearbox-to-center one, and even then you still have one wheel. We've only had one problem, and that was when a thrown/broken chain jammed between sprockets at the same time that we got stuck on an inner tube at the end of a match. It was fixed within one timeout.
