In addition to gearing, the torque output depends upon wheel diameter and coefficient of friction. We were running on 4 AM omniwheels and 2 AM kitwheels, all 6" diameter. We were heavier than y'all, I'd venture, as well.

What sort of wheels did you have and what size were they? Did you have an additional chain-based reduction after your 12:1 gearboxes?

I think we probably could put more torque to the floor, as things go, but momentum ought not be underestimated and we were quite a bit slower than you.

Re: 2007 Drive Train Poll
Custom 2 speed dog shifter running to 6 custom 4 inch aluminum wheels.

Simple, effective, and potent. We held our own and actually damaged several teams drive systems when they decided to play head to head against us.


Keep an eye out, our '08 drive train should be something of a spectacle.
