The engines suplied have stator lenght of only 20mm and Kv 754 rpm/volt. They are not the motors i bought.
I'll claim.

I'm using this motor in a sig kavalier .46 nitro conversion project of mine. It's coupled with a 60A HK ESC and a 5s 5000mA LiPo and a 12x6 prop. Results are very good! I can climb vertically as long as I want and can comfortably fly around 15 minutes. The motor and battery stay cool but the ESC had to be moved to the underside of the plane to stay cool. You might want an 80A ESC

The shaped motor mount shipped with the motor didn't fit but everything else fits just fine. I made my own mount out of balsa/ply so that wasn't a big deal

I have around 20 flights on this motor so far. Performance is excellent. I recommend this motor.

Ich habe 2 Stk. von diesen Motoren gekauft. Leider sind beide unbrauchbar. Unwucht und Aussetzer lassen es nicht zu, die beiden Motoren fr einen Einsatz in einem Flugzeug. Ich bin sehr enttuscht.

Ich habe 2 Stk. gekauft. Leider bin ich sehr enttuscht. Ein Motor hat soviel Unwucht dass er nicht eingesetzt werden kann. Der andere Motor hat Aussetzer und kann ebenfalls nicht eingesetzt werden. Ich kann diesen Motor nicht empfehlen.
