Mamba Monster Amp rating?

Ah ok, thanks for clearing that up. I'm waiting for info on the diff ratio and final ratios etc on the Genesis differentials and transmission, but in the meantime I checked out the Flux tranny and gears with 12 pinion and 60 spur, aimed at 30mph top speed and 3 second to get there, and it only drew 30 amps. That would be a nice setup, sort of slow but ah well.

I'm guessing monster truck differentials are somewhat similar, so I'm estimating that I should be safe with a low pinion like 12 and 60 spur.
