Care to share some specs, maybe a transmission close-up?
I'll try to get a transmission pic up soon. Its two stage and single speed gearbox, with a roughly 7 to 1 gear ratio(1.8 itcr). On a four inch andymark wheel, it should be traction limited. I thought about designing a custom ball shifting version, but I only spent a couple hours on this design, so I never got around to it.

8 CIM drive?
Can you say "Popped our main breaker"?
Don't worry, you will!
I don't really disagree, but I find it interesting you would say that without hearing what the final gear ratio is.

If done right you'd get a decent performance increase and exactly ride whatever line you set in terms of net current draw.

You both are correct. The final gear ratio was not stated, and torque limiting over time could be quite advantageous.

That said, with the size of fields we play on and the wheels that are available to us, 6 CIM drive seems to be about the limit of practicality.

Please don't get me wrong, I really like this design both for it's creativity and it's aesthetic. I would love to see how it actually performs. I know with the right final gear ration, you could drive it continuously at full speed without tripping a breaker. The carpet might not like it, but that's not the point of this design.
