How many CIMs in your drivetrain?

how about 6 CIM drive?

We prototyped a 6 CIM drive during the offseason using VexPro's dog shifting dual-speed gearboxes, and it works fantastically.

We also did octocanum for about five years, and could beast through just about everyone...except for 6 CIM drivetrains, despite being geared down about as preposterously low as you could get, and with great traction.

I would strongly recommend not going to one per side--you'll lose every pushing match you get into with a four-CIM drivetrain, and each of those CIMs are going to draw more current, work harder, get hotter, and drain your battery more than four or six. The only advantage is weight, and it's not a good enough tradeoff.
