Unfortunatly, I do not have a good picture. The one I attached is the best I could find. The lower set of wheels shows the gearbox through the middle wheel. The upper set shows the front wheels, which were not a problem.

I saw setups like this on a number of teams that had chain issues (and actually saw 25 chain breaking).
From what I could gather the AM Traction (Plaction?) wheels, with the tread attached, has a slightly larger circumference than the other wheels. Since both have good traction (.9+ CoF) the difference in distance traveled causes the chain to jump over time (~ 1 minute into matches). Try putting slick wheels, or zipties (Lower CoF) on the front wheels (the set chained only to the middle)
