Shaft specs for CIM motors

[billbo911]

While Andy has provided some very valuable information here, I'm not sure that it applies to this situation or not. Yes, the CIM and Mini-CIM share the same output geometry and circumference, but they are not the same motor.

The failure described above was of a Mini-CIM, not a CIM. So, what specifically are the differences in the two motors that can account for this failure? I know many teams have been prototyping with direct drive CIM shooters, and I don't believe we have seen failures of those. Is it just the Mini-CIM that doesn't like this treatment, or just this one motor in this one event?

Our mini-CIM did the same thing, it ended up cracking the top plate of the mini-cim... we are going to try it with it super bolted down and it supported from more spots...

I imagine you're using the pneumatic wheels or something like them to shoot as our team is doing... make sure you align the motors properly, center them, and balance them, plus check to make sure the wheel is actually on right (we found that one of our wheels wasnt on correctly and so we had to shave the inside (rubber) down to make it match
