I find this very hard to believe. We have known and trusted and designed to these specs for 9 years now. For the CIM to stall at less than 40 Amps, would mean its peak power is significantly less than published, yet our robots seem to perform to expectations every time.

To be honest, I've never run one through any sort of current measuring device, but I certainly have tripped 40 Amp breakers with them. I know some teams have done current monitoring (and if I recall, some sort of FIRST-sponsored program at IRI 2008?). Do any teams have any current draw data they'd like to share?
