Do yourself a favor, use JVN's calculator.

I got to ask, how are you doing your center to center distances on gears?

Edit: Forgot to say, while I wrote about the max power numbers up there, the CIMs are capable of putting out 343.4 oz-in at stall current.
Thanks for that link. I got all the stats from probably the same data sheet you did for the CIM's, the normal load was picked because it would prove to some more conservative members of our team it could maintain that torque. The gears are standard andymark shifting gears for the most part and in addition their charachteristics were placed with the gear portion of design accelerator on Autodesk Inventor. On top of hand calculations to ensure proper meshing. The modules are being lasercut to ensure the precision.
