●3700KV high efficiency, high torque, 9holes, 6poles outrunner brushless motor.●Feature! 1.New longer rotor and stator make the great torque performance. It can continuously support the power even though fly extreme 3D. 2.Motor covers use thread to fix, features bump resistance. 3.Pure metal high speed CNC precise processing. 4.The standardized automatic winding production. Low KV specification error. 5.Special cooling fan design. Effectively reduces load rotation temperature of motor(load temperature of outer case: 45-55℃.Test ambient temperature: 20℃). 6.Light weight.High efficiency.Long service life. 7. approval(0506054)、 approval(0506069)。
