Thanks, didn't know that. That should save some time and cost.

The gears will be custom made. I'm still looking into where, who, and how much, but it doesn't look like it will be that bad.
One large CIM ends up being more efficient, and when coupled with tank tracks, is plenty to shove just about anything around. That also leave 4 high power motors for a beastly manipulator.
Yes, the lower speeds help make this gearbox nice for the Outback track system, with the higher gear set as default. Then, when you need to get into a pushing match, you downshift and "politely escort the other bot across the field."
