    Advantages

    Unmatched Power-to-Weight Ratio — Generating up to 2898.9W of max power from a 300g motor is an engineering feat. This allows your aircraft or equipment to carry heavier batteries and payloads without sacrificing flight time.

    Exceptional Thermal Efficiency — Despite pulling massive current (up to 74.56A), the motor runs incredibly cool. Under a 100% throttle stress test for 2 minutes, the internal temperature stabilizes at only 36.4°C (330KV) and 31.7°C (560KV). This thermal headroom means you can push the motor harder for longer without the risk of demagnetization or burnout.

    Heavy-Duty Industrial Construction — Built to withstand extreme mechanical loads. It features a robust 6mm output shaft with an M6 CW thread, a standard 4x M4 mounting hole pattern (30mm), and a solid 300g frame.

    Ready for Plug-and-Play — This motor is a direct-drive powerhouse, eliminating the need for complex gearboxes or belt drives, thereby increasing overall system reliability.

    Applications

    Extreme Heavy-Lift Industrial UAVs — Agricultural spraying and seeding drones, heavy cargo delivery drones, and long-range pipeline inspection aircraft requiring 14-inch props and massive payload capacities.

    eVTOL & Advanced Air Mobility (AAM) — Ideal for full-scale eVTOL prototypes, personal aerial vehicles, and heavy-lift VTOL fixed-wing hybrids requiring reliable, high-torque direct-drive propulsion.

    Large-Scale VTOL & Fixed-Wing UAVs — Providing the raw power needed for large hybrid VTOL aircraft and massive survey planes to take off vertically and transition to forward flight.

    Industrial & Laboratory Equipment — Perfect for high-torque industrial blowers, wind tunnel propulsion fans, heavy-duty centrifugal test rigs, and aerodynamic research equipment.

    Wind Energy & Turbine Testing — High-torque, high-RPM generator testing and micro-wind turbine prototyping due to its excellent efficiency curve (up to 5.8 g/W).

    Heavy-Duty Robotics & Direct-Drive Systems — Suitable for large mobile robots, heavy track drives, and industrial automation systems where a compact, 2.165 Nm direct-drive motor is required.

    Giant-Scale RC Models — Massive scale RC planes, large gliders, and heavy-duty RC boats or cars requiring professional-grade power systems.
