How are you planning on adjusting the backlash on all those gears, or are you not worried. I cant see it being a major issue, but i thought id ask.

I agree that belts would be lighter, though we really haven't had a weight problem the last two years. We actually have been struggling to get up to 120lbs, to get more traction. Right now I would take the smaller footprint over the lesser weight option.

I haven't thought about the backlash, several teams have done gear drives and haven't mentioned it being a problem.
