This is the new 430XL motor 3700KV

• 3700KV high efficiency, high torque, 9holes, 6poles outrunner brushless motor.
• 1.New longer rotor and stator make the great torque performance. It can continuously support the power even flying extreme 3D.
• 2.Motor covers uses 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.
