Tried it yesterday some minutes with 23x8 woodprop. Batteries: 2x Zippy 5s1p 5000mAh 40C. Current: max. 78A Voltage: 38V at full throttle. Power: 2870 Watt. Iwill try it again with a biela 20x10 4blade prop.(haven't received it yet).
I am running this on a 27pcnt Cap-232 Using 10s 5000 Lipo, 180 Amp Yep ESC, and a 22X8 prop. I get explosive response and vigorous unlimited vertical. Smooth throttle-up and about 8 minutes of hard-driving flight. I am very pleased with this motor.
I have had this motor for some time now, powering my 1/3 scale Piper Cub, driving a Turnigy 24x12 prop on 10 Cells. About 115 Amps, 4800 watts on full throttle on freshly charged batts. It has operated flawlessly, and the quality of construction seems very good. I am completely satisfied with it.
My electric motorsport team used this motor to great effect on our E-bike and also on a Kepler style Friction Drive:

Vraiment super moteur de bonne qualit avec un beau son. je l'ai mont sur un T-27 Tucano de 2.56m et 14Kg. avec l'ESC DLUXE de 250A je vol 6 minutes. L'hlice est une 22X10 bois et les Lipo sont des 5000mAh en 20C. Vraiment bon moteur.
Excellent motor. Got it on a Extreme Flight 88" Edge. 5300Watts limited - total about 60 flights. 4:30~6:00 mins light son 12S 5000mah on 24X8 Carbon Falcon
iam using on pilot extra 300 88 inch with 22x8 prop on 12s 8000 mah zippy (6sx2) with normal flying 6 min battery remain 60 pcnt feel it wil give 10 mins ,with 3d flying 8 mins with 20 pcnt battery remain .I recommend this motor
Nice motor, not had a chance to run it up fully yet. Had it running on a 4 cell just to get the motor spinning the right way before I bolt the prop on. Hopefully I'll have this motor running properly on 12 cell very soon. Will update review once tested. Thanks very much HK!! :)
Ich Fliege diesen Motor mit 10S, 5000mah, mit einem Menz 24/12 Elektroholzpropeller, in einer Pitts S12, mit 170cm Spannweite und 8,9 kg Abfluggewicht und in einer Extra mit 223cm Spannweite und 8,5kg. Ich habe einen Standschub von ca. 12 kg. Vorher bin ich immer 55ccm Verbrenner geflogen. die Leistung dieser Kombination mit 10S ist Powerfull und leistungsm**ig gleich wie ein 55ccm Verbrenner.
Dieser Motor hat einen wirklich geschmeidigen Lauf und eine Menge power. Ich betreibe ihn mit 10s und APC 20 x 10 in einer Piper J3 von Hangar 9 und bin sehr zufrieden.
