I think we would all rather have a chain break then the gear box, although if everything is designed right, a key should break first before too much damage is caused to any key hard to replace component, or at least you would hope. I like to build everything strong enough, and robust enough to not worry, but the drill motor gear boxes where my weak link last season, but we powered along, and did a lot of pushing just with he cims, sometimes I would swear the drills had to be helping out the cims, but then I'd get it back in the pits, and sure enough, we would have wrecked another set of drill gb's.
