Good note on the size of the com's.
Something else to watch, as I've see this several times on CO-27s lately.
When cutting the com, watch the first cut. Watch for one lamination being cut and not the others. This is a sign of it coming loose from the base material. We have a trintiy sponored driver who tosses me his used up motors for parts to repair other racers motors, Many Cudos CATO!! Anyway, even he had one separate. Once this happens the motor is almost toast. If there is enough thickness of copper, it can run, but days are numbered.
