I recently bought this motor because I need 800 Watts for my Great Planes RV-4 weighing 2.9 KGS and I want to fly it on 4 cells.
With a Turnigy light wood propeller 13x6 I only get 500 Watts. I use the HobbyKing 70A ESC 4A UBEC in combination with this motor.
I programmed the ESC as follows:
Angle of entrance = HIGH
PMW frequency of motor = 16K
Propeller = Turnigy light wood propeller 14x8
With full power I get 950 Watts and the motor pulls 68 Amps
Now I can't wait to get the RV-4 flying.
I will certainly buy the same motor for my Great Planes Ultimate Biplane.
