After this afternoons flight at the basketball stadium which mostly consisted of hovering about I was a little concerned about the outrunner temperature. I could smell the motor after the flight and it was hot to touch. Battery and ESC were fine and barely warm.

Im running a linier throttle curve, and 40,51,65,74.5,84 pitch curve which outputs -2 to +10 or there abouts. Im guessing blade pitch is exceeding RPM requirments and putting the outrunner under too much load. What would be the best method to reduce motor heat, increase head speed, or reduce reduce pitch to RPM relationship to reduce motor load. Higher head speed with reduced pitch seems to me to be the best path to follow. Does this make sense or am I off track? My other CP heli motors dont run this hot at all.
