Before you do that i would work out the power you could achieve with just the CIM and the Drill's. Those 4 can pull 160 amps which theoretically is enough to trip the breaker(it really won't). Secondly you need to find really high traction wheels if you really want to use that power. i think the technokats tore up the carpet once with that 6 motor system at nats(they had those metal treads). It might have been a different team, but either way they had more power than they could use.
If you're working on it now. You have time to really calculate it all. Thats what i'm doing. But i'm going for something slightly different.
My plan
