This is the Dualsky XM6352EA-10 Brusless Motor. The new V3 Dualsky XM6352EA-10 features a new Durotate rotor with an optimised back cover that reduces air noise, a new front cover that offers better heat dissipation and a higher density rotor and shell that reduces vibration. Add to this the use of thicker wire with high-temperature resistance and the net result is more power and improved efficiency.
