Re: basic question on using CIMs with TB Minis

When we were designing our shooters for both the alpha and beta bots we took the 14 or so mini CIMS that we had and measured their actual rpms, both forward and reverse. We found them to range from about 5650 rpm to 6440 rpm and it didn't matter whether it was forward or reverse. The only noticeable difference that we did discern was that 8 of them ran forward faster than reverse. Some of them were strangely different-- running 550 rpm faster in one direction vs the other.
We just used these numbers to mate a pair so that we were able to have the same speed (within 40 rpm, no load) with one forward and the other in reverse.
