Out of curiosity, how would a 2CIM + 2 MiniCIM drive compare? I've often wondered if this was a practical weight saving option or if the performance drop would make it not worth the trouble.
Also, what are the effects of leaving the gearing on an xCIM + xMiniCIM drive identical between all motors? We've always just geared MiniCIMs the same as CIMs hoping to get a few extra RPM out of the drive. Is this practical or is there some downside I'm not seeing?
