Well, it works. It looks quite pretty. But it's build quality (inside) is very poor.
It has 2 "poles" inside. Really hard to call them poles, as there are no actual metal poles, but the windings squeezed together neglectfully...
I ordered two, one does 22560 rpm, the other one 24360... If you need two to work together then I recommend using something of a better quality...

excellent motor, i used it with a 3s 3A 30C LiPO and with a 6s 2,2A 30C Lipo. i use this motor in a rc speed boat and i am too happy with the speed and the power. with the 3s lipo the motor only use 36Amp under load, but with the 6s i get peaks around 59Amp. i am not scared about it because i use a 100A speed controller and it never be more warm then my fingers.



PS: this motor with a 6s Lipo runs with a 40mm prop around 80km/h :P

This motor is very good for EDF however, you must take into account that the external diameter is not 28mm! Due to the cooling fins, the diameter is much larger. The solution is to mill the forward fins to precisely match the diameter you need. Also, be very careful not to bang the motor shaft because it is only 3.17mm and can bend easily.

After using these motors for more than one year I can tell they still give 100%. Even with part of the fins removed to fit inside the Haoye 3" EDF, the thermal resistance is excellent. Motor runs on 4S lipos at almost 37A constant: no problems.

I used this Motor for 92mmDF.

(4S,2500mAh,21-31C))

There is splendid power in Motor.

However, the installation of the connector was insufficient.
