Once up to speed, the only external load on the CIM is windage and vibration due to unbalanced wheel. At 12 volts and 4000 rpm, the CIM would be drawing 34 amps and generating 250 watts of output power at the shaft. If you guys have a clamp-on ammeter, it would be most interesting to see what the current draw actually is.

Not sure what you mean by a "half dead" battery.
Do you plan to do closed-loop control of wheel speed? If so, when you get the speed sensor mounted you could provide some useful data to the CD community showing how rpm affects the frisbee flight path.
