There's no comparison between feigao and novak. I've tried the hv4.5/7.5 and Feigao 8xl/9L. The feigaos heat up much faster and are much more problematic. You can't even gear them so you can get more power out of them than novak.
You do have to use a much smaller pinion gear with novak motors, but gearing them down doesn't result in much of a loss in top speed in my experience. The only thing you have to watch out for when running the novak motors with the mmm is demagnetizing the rotor. The novak rotors seem to be suceptable to demagnetization at lower temperatures than other motors such as feigao or castle. 175F seems to be the absolute maximum temperature.
IMHO its just a better idea to go with a castle motor. They are more solid units, and cogging is almost non-existant. If you do have cogging, will increase temperatures and put more strain on the rotor.
