I have tested three of these motors over several years on 3.5 to 5 lb airplanes. It is an excellent motor in it's power output vs efficiency and weight. It has some slight cogging vibration and could use better bearings. Better yet tweek the cogging out, put better bearings in, balance it, include a mount and can end prop adapter. Charge an appropriate price increase, I'll pay it with that tweeked out. I just can't seem to find anything else that does the same job.Sick motor! I don't know why is it so cheap!Got the motor and tried it on several batteries with different loads.
Very low efficiency motor on 4S battery - 450W 4S 17x8 or 500W 4S 16x10. Gets worm and power drops slowly. also gets very worm on 6S 13x8 700W.
Expected better :(Just got the motor.
4S 17x8 ~500W
5S 17x8 ~600W
6S 15x8 ~600W
The motor gets hot. I will try the first combination on my YAK54 ~1.8Kg and wingspan of 1.4m. hope it will last ...Wow a light weight powerhouse! Is a very light motor for the output and runs at high voltage so gains efficiency seems well balanced and smooth - just goes like stink.static ground test : 31 Amps on 6S with 13x6.5 APCE, motor gets fairly warm after 1 minute but generates a lot of thrust ! Reversed the shaft because I did not trust the small C clip.
Flight report scheduled for tomorrow.Shaft is pretty soft, it bends pretty easy. Fortunately it is no problem to buy spare shaft in my local shop. Engine cannot handle 1000W, it overheat way too much. 800W is maximum for this motor on 6S.A real powerhouse on 6 cells. Using a Xoar 15x8 in static test I get:
Approx 9lb thrust
In flight peak power was 965W and current 41.6A.
i had reservations about all that thrust being transmitted only though the little c-clip that hold the shaft in, so i reversed the shaft and put a bolt on prop adapter on (motor has drilling for one) and used a retaining collar on the back.
Steveottimo motore ho provato con una 15 X 8 ho ottenuto un tiro di 3.3 kg
con circa 800 w
con una 14 x 7 ho ottenuto 2.8 kg e 700 w circa
necessita' pero' comperate a parte il mozzo e il supporto motoreOttimo motore l'ho montato sia su un extra 300 della Kyoshio sia sul mio Yak 54 carbon zeta con regolatore Turnigy da 85 ampere spinge tanto che gli aerei vanno su a candela alla stessa velocit dell'orizzontale lo consiglio a tutti.
