High Efficiency, Unlocking Extended Flight Potential

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

Resistance reduced by25%

Efficiency at 3kg thrust point enhanced by8%

Efficiency at 4.2kg thrust point improved by29%

*Note:Test data is obtained from HOBBYWING’s self-developed testing platform. Test results may vary slightly due to differences among sample batches.

Powerful Thrust, Meeting Higher Payload Demands

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

3115-900KV paired with 10×5×3 propeller:

Maximum single-axis thrust reaches5.08kg

An increase of more than 21%+
compared with motors of the same specifications from other brands

Paired with HOBBYWING’s self-developed 10×5×3 carbon fiber propeller

Maximum thrust can be further increased to5.25kg

High Thrust-to-Weight Ratio, High Power Density

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:

High Power Density

Thrust-to-weight ratio increased by7%

Peak thrust enhanced by21%

Peak power density improved by18%

Efficient Cooling

Efficient Cooling, Stable Continuous Output

The 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.
