Re: your thoughts on the FP CIM/2.5 CIM motor drive setup versus 2 2.5 CIM motors

I don't have much in the way of quantitative data to offer you, but my drivers complained immediately that we no longer had any advantage in pushing matches, and we obviously struggled to turn in high gear. Both of these problems could have been mitigated with a better selection of sprocket reduction, but if you do your math based on the FP specs and then swap the motors later, you're in for a world of hurt.
really? When the speeds are matched, the FP doesn't even come close to the torque the small CIM puts out.
