Xmotor EA brushless outrunners for air

Partial motors upgrade Durotate technique(XM4255EA-XM6360EA)
Prolong the lifetime of rotor in the environment of highpower and high torque
Improve running efficiency in middle RPM range
Optimize the shape of back cover and reduce air noise
Notice: Durotate rotor doesn't compatible with previous motor

features:
Improved front cover, better heat dissipation
Rotor with more beautiful star design
Increase the intensity of rotor and shell, reduce vibration and bear more load 
Switch to curved magnets with higher grade
Use high efficiency silicon steel
Reduce the air gap of the stator and rotor, increase efficiency
Use thicker enameled wire which is resistant to high temperature, improve insulation and impact resistance
Compared with CA, EA power is increased by 10-20% and efficiency increased by 3-5%
More options for KV value, suitable for practical use
Add XM2838EA & XM4255EA to EA series, which CA series have not 
Motor mounting holes and shaft diameter compatible with CA series
Accessories compatible with the CA series(except new added models)
8mm propeller mount with thinner threads, propeller not easy to loose
