So far, I haven't built a better motor & controller set up than the 6-turn, 2-in hand, 14G, dlrk/wye terminated motor...run the thing with a 12 or 18-FET xie-chang with a 6-Kw limit on 20 LiPo cells & you will not find a better RC power combination [with external hall sensors]...The motor finds balance right there, more rpm's (voltage) brings iron losses to un-acceptable levels, more current & the copper insulation is going to fry.
