Well
I have now more than 150 flights on my ACn F3A motor, and it is behaving nicely.
It have a nice smooth power curve, lots of power, best prop for it in my finding is PT21x14E, where I fly whats your advance program, and using in the area of 26-2700 mAh.
No heating problem, noise non excisting, it have a bit different sound than the Hacker have, but sweet sound.
Grease it every 50-60 flights with MOBILGREASE 28 and you will have no problem.
Currently I'm in second spot in the Danish nationals, so I can only recommend this motor.
Ohh forgot, I'm using YGE80HV speed controller
