Featuring fully hand-wound windings with a high slot fill rate, 0.1mm low-loss stator core laminations, and strong arc-shaped magnets, the motor delivers higher efficiency, providing enhanced endurance for long-duration and complex filming missions.
Taking the 3115-900KV paired with a 10×5×3 propeller as an example, compared with motors of the same specifications from other brands:
Higher Efficiency
Delivering stronger power output, the motor maintains ample power reserve and flight stability whether carrying large imaging equipment or performing high-speed chase shots. It also meets the high thrust capacity requirements of industrial heavy-load applications and FPV racing competitions.
Powerful Thrust
The newly designed high-power-density platform achieves a better balance between lightweight design and power output, combining agile control with robust power performance. It provides ample power reserves for complex flight scenarios such as dynamic tracking shots and high-speed maneuvers.
Compared to motors of the same specifications from other brands, the 3115-900KV paired with a 10×5×3 propeller delivers:

Efficient CoolingThe motor’s propeller mount adopts a high-density self-cooling fin structure, rapidly dissipating internal coil heat during flight and effectively reducing operating temperature rise. It maintains an ideal operating temperature under heavy-load and continuous-flight conditions, extending continuous operation time while improving motor reliability and durability.
