I've been looking at hobbylobby.com and can't find a 1HP brushless motor let alone a 2HP. They are all like 300W and that is with a gearbox. I think we can accomidate a 12" prop, so we should be able to get enough thrust if we can find a big enough motor. Maybe even two of them.

Is a battery capable of pulling 40 AMPS continuously? That seems like a crapload of current

Can you double the voltage on these motors? If we could do that we could double the RPMs and the Power. I have a feeling they would get to hot, pull way to much current and ruin everything

The gearbox you would reccommend be like 3:1? or even bigger than that.
