Sorry I wasn't more specific guys.... I was crunched on time.

So a better explanation.

Dual motor drive using the "Nothing But Dewalts" transmission setup. Big thanks goes out to Joe and Joe.

The motors are set up so that both will spin in the same direction (Not one in reverse) and linked to our ouput shafts with sprockets and #25 chain. Beings the gearing on the Dewalt transmissions are 12:1, 4:1, and 3:1, we have the additional 5:4 gearing in our sprockets.

The 2.5 inch wheel accounts for our main wheel turning our treads. The problem happens in a straightline, not just turning, so I know it's not a tread dilemma.

It does spin just fine in any gear while up in the air, but with the specs on the CIM motor, it doesn't make sense to me why it wouldn't work on the ground. At approximately 110 lbs this year, we should have no problem, as the torque works out to be higher than our 130 lb robot last year. Unless the Dewalt gearbox's efficiency is under 70% that is.

I imagine the problem is the spike when starting them, but I've got amp meters hooked up and they've pulled 37 at the most.
