Anyway: It looks like those sprockets on the wheels are kinda small. I can't see exactly how many teeth they have, but if you double the number of teeth, you double the torque (but cut the speed in half).

Try something like that.

Alright, but are there any certain stores/companies you know that could get us the sprockets? We want to avoid buying over the internet, a lot of our parts came in later than they told us, and we need to fix this soon, or we'll be stuck in 1/3 areas for the whole competion.
