Multi-rotor UAV Efficient Motor U8II

Multi-rotor UAV Efficient Type Motor U8II
Efficiency inrease by 15%+
New arrival with 14 patents, sine wave features, matches with ultra-light propellers, FOC electric speed controller, solver winding



Flight time 5% longer


Imported Custom Silver Wires
Fast current flow on silver wires surface imporves motor response speed for easy control over aircraft. Silver winding greatly reduces copper loss and helps lower motor heat by 30%


Magnetic Circuit Optimization
Curved magnets in new U8 are with less magnet space.
Optimized design help save energy during flight.

Maximum Thrust 7.3kg
Heavy load 
With the fall of motor temperature, the maximum thrust of new U8 reaches 7.3kg from 5kg which doubles the aircraft payload.


A maximum tempeature of 35C call can be achieved.
Data is obtained at 32V+500W motor running 10 minutes


Motors Work at Ease in high Temperature
Centrifugal air-cooling system, built-in array for the efficient heat dissipation. The terrific cooling performance guarantees the reliability during running. Operating in 50C environment disdainfully.


Motor Protection IP45
Heavy rains and desert are not qualified to stop you from flying.



Patented Technology
Protect motors fromsand, dust, foreign matters and magnetic particles.
