I'm not sure if it is the motor or the combination with the YEP 18A ESC, but I did not get the performance or behaviour desired from this motor, therefore replaced it in my 250 size helicopter. The motor is still ok and might find a usage somewhere else

As always with NTM, very good high quality motor.

Runs quiet and efficient, good bearings, balanced from factory.

Great motor for an HK250GT build. Pinion with the kit was a tight fit but I used a vice to press the motor and pinion together.

Got this one for HK250. Quality is amazing! Motor looks very nice, made with care and precision. Runs very smooth and the sound is so soft and pleasant. With a standard 800mAh battery, I am getting about 6-7 minutes of calm flight, but I think it could be more with different helicopter pitch and rpm settings. With current settings there is a lot of spare power left and it is hovering with only half of a throttle on. Helicopter weight is 349g. Conclusion - very good motor for a very good price!
