4725-520KV/Gold 4th generation brushless motor is suitable for Steam Dancer 700 helicopter, using 6061T6 aluminum alloy high-precision CNC machining. The unique design of three large-size bearings, 180 degrees of high-quality NdFeB strong magnetism, and built-in high-efficiency active heat sink bring ultra-low temperature and effectively improve energy conversion efficiency.
The fourth generation of golden brushless motor adopts 1.4mm single-stranded thick copper wire, 7T+6T YY precision winding method, pure manual high slot full rate winding, strong power, but the vibration value is extremely small, can stand on the plane coin, specially designed for 700 class competition helicopters standard power motor.
