The overall reductions are 5.45:1 and 13.75:1, which are a little fast for 2 CIMs driving a 3.25" wheel. I plan to add an rs-775 to the gearbox.

I'm not sure adding an rs775 to the gearbox is a good idea. I'm pretty sure the rpm curve is different for the rs775 as compared to the cim (whereas I think the miniCIM is meant to have a very similar/the same curve). This could mean that the motors are trying to drive each other to some degree instead of all working together to drive the wheel.

Of course, I could also just be completely wrong here ... I'd love someone to confirm/deny what I'm saying with a better explanation.
