Woooah!

I hope you're not direct driving those. CIMs spin at an unloaded speed of about 5400 rpm. Direct drive would be uncontrollable. If anything, running them through a banebot, which would have a 4 inch wheel mounted on it, that would give you a calculated unloaded speed of about 6 fps... So I suggest using the banebots. They're actually really nice transmissions, they just get a lot of bad rep.

I'd suggest using two globes direct driven to some skyways. We use those in our offseason competition a lot, and they work great.
