Brushless inrunner

Runs great on 6s lipo battery 12 blade 70mm with no problems ,pushes my f104 to 112 mph not too bad I guess, but might change to a 9 blade too see what happens.

Strong motor

Make sure you set the timing to"LOW" about 5 degree. Someone advised me to set the timing to high and the fan bolt backed off because the motor was backfiring as a result of the timing being set high.

Great Set up for 12 bladed edf

I'm using this motor with the 12 Bladed metal EDF housing. It draws 68A of power at full throttle with 6S 3000mah 40C battery. It is very quiet compared to my original set up with 5 bladed EDF, and delivers 30% more thrust in the YAK130. I am still getting a 3minute flight time with this set up.

Great Motor

I have installed this on my SU35, F104 and Yak 130. This is a very nice motor. Freewing should list the recommended timing and PWM frequencies.
