yeh i can wait around and gear it really high and run a smaller motor i guess. problem i see with the MMM is that the motor is only for 2200 kv... even if it makes something crazy like 2000 continuous watts(2.6hp) you still probly wouldnt be able to gear it low enough to run at the speeds im looking for...
I have a 22/45/2 that I am going to run on 6s2p a123. I got it from a buddy who ran it on 24 nimh cells. It was very impressinve in his boat. I will report how it performs in my buggy.
