CIMs can get closer to stall conditions multiple times before burning out. We've had BB550's & 775's smoke after a few iterations of running them around 30-35 amps for prototype lifts. I'm a bit smarter now than I was then so I can calculate for some safety margins, but for a drive train I don't think there's enough safety margin for these motors.

I think, iirc, 25 tried 2 BB550's + 2 CIMs in '08, and said they had to replace the 550's a couple of times. I think they wound up going down to 2 CIMs only in Atlanta? I could be mistaken.

Of course, I could totally be missing something; I wasn't around for the drill motors of '04 so I don't know how many of those burned out on field.
