Li-Po or NiMH? I'm confused.

Mike, there's not a huge difference in price between the Kokam 3200 3 & 2s cells and the Polyquest 4400 3&2s cells. Is there any reason why you would go for the Kokams over the Polyquest packs?

Also I'm not clear on the relationship between the motor turns and current draw. It appears that the more turns the motor has the lower the current draw, which is then easier on the batts and the controller is that right?

If I understand things right the best operating range for the feigao motors is 35,000-45,000 rpm. With 18.5v that means a motor with between 1891-2432 rpm/v, which means that a suitable motor could be 10L,12L,13L or 7XL,8XL,9XL. The fewer the turns the higher the amps, but what impact does this have in a real situation.

I'm just trying to get my head round this:C:
