uhm.... just wondering, but why are you calculating everything out based on one point along the motor's torque curve? Personally, I just find a spot that makes me happy (and the Victor drive happy) and use that as my torque numbers at that rated speed.... then i rate my top speed at just rolling friction, etc, watching what current i'm at, etc....

RapidShare'd the torque specs for the 2.5" cim. I'll see if i can dig up my copy of the 3" cim torque curve. Post with ?'s or //s.
