Re: High torque that can be purchased.

We used a BaneBots P80 144:1 transmission driven by a CIM with and additional 4:1 of chain reduction. The P80s seem much more robust than the P60s. That design got us though two intense regionals, including the Oregon Regional with you folks, and we never had a single problem.

That did mean we needed to use our 775s as the second motor on our Supershifters, along with a CIM on each side, but that also seemed to work out just fine with the CIMulators.

The thing we've learned along the way is FPs, and I assume 775s, really don't want to be run at low RPMs or close to stall where as CIMs don't seem to mind (much). In 7 years of doing FRC we've never burned out a CIM where as we have buckets of fried FPs and the like. I'd also avoid Banebots transmissions above 144:1 unless you are sure you won't exceed their tourque specs.
