One other thing:

Even with my heavy nimhs, I liked the way my 300 motor powered Estarter flew. (Like it even more with the lighter lipos.) Most would put it in the weenie class, but to me, it's a trainer and that's how I like to fly it. It would cruise at about half throttle.

Any brushless motor that puts out 150 watts on a 3S lipo and a 9 or 10 inch propellor would satisfy those who gave up their dream of being astronauts and took up RC instead. That gets you almost twice the stock power.
