I'm not sure, exactly, what the magic number of CIMs would be before it becomes pointless to add more... but I'd bet that you are within +/- 1 motor.

Perhaps a shifting gearbox with two or three CIMs would actually provide both better acceleration AND a higher top speed.

I am not too worried about tripping the main breaker. If it does happen, I guess lesson learned. I will take off the mini cims at that point. Seeing Spectrum 3847 using the same combo of motors on their drive train gives me some confidence to run this setup. I do agree that shifting would be ideal but the purpose of this gearbox is to actually go into a tex-coast drive. The "shifting" will actually done by deploying your traction wheels which have a second reduction.
