Dualsky XM4255EA-12 V3 520Kv Outrunner Motor

- Prolong the lifetime of rotor in the environment of high power and high torque (for example: 3D flight).

- Partial motors upgrade Durotate technique.

- Optimize the shape of back cover and reduce air noise.

- Improve running efficiency in middle RPM range.

- Improve front cover, better heat dissipation.

- Rotor with more beautiful star design.

- Increase the intensity of rotor and shell, reduce vibration and bear more load.

- Use thicker enameled wire which is resistant to high temperature, improve insulation and impact resistance
