BrianG,

Man, you're up late. I'm a chronic insomniac.

What I meant was this. If I am running "X" motor on 4S to attain 30,000 rpm, then running motor "y" (a higher turn motor) on 5S to attain 30,000 rpm should result in less current draw, while doing the same work. Is this right?

I wasn't talking about going from 4S to 5S on the same motor and expecting the current draw to go down. If I stay with 4S, I'll probably go with the 2200kv motor. If I go with 5S, I'll probably go with the 1700kv motor (or maybe even a higher wind). Although both the 2200 on 4S and the 1700 on 5S will turn about the same rpms, shouldn't the 1700 on 5S draw less current?
