With 6 full size CIMs on drive, you can trip the main doing full forward to full reverse. It's scary to think it could happen in a competition. Also, once you've driven for a minute or so, you can get the battery voltage low enough to cause the radio to drop out. Those CIMs can draw 100 amps at stall. It'll take a few seconds for the 40 amps to start tripping, but the 120 amp breaker trips quickly when you try to put 600 amps through it....

We ran a 6 motor, 2" wide wheel 6WD last year. We had troubles popping the main breaker but not the 40A breakers. Because your motors are sharing the load the current is actually LESS per motor. Therefor it is actually HARDER to trip the 40A breakers.
