What would explain the difference?
I used CIMs at 5310 rpm free speed and the gearing showed on the blog posting.
Thanks.

We used 5550 rpm free speed. Our measured efficiency on the bench ended up being 90-95% with a free speed of about 18.5 ft/sec with no weight on the wheels.
Would FIRST be as amazing if not for CD? I mean it would still be this amazing place for students and mentors to be but the explosion of innovation and gathering of people together across communities has to have been greatly effected by CD. - dodar [more]
