What makes the 14-pole stator ideal for fixed-wing aircraft?
The Spektrum M-SPMXAM4770 motor with 4mm bullet connectors and 14-pole stator features a high-pole-count design that enhances magnetic resolution and reduces cogging. This results in smoother throttle transitions, quieter operation, and more precise control during aerobatic maneuvers. The stator configuration improves torque consistency at low RPMs, making it ideal for sport and 3D aircraft that require stable lift and responsive pitch control. Combined with rare-earth neodymium magnets, the stator ensures long-lasting performance and minimal vibration across all flight conditions.
How do the double-shielded bearings improve reliability?
The Spektrum M-SPMXAM4770 with rare-earth magnets and double-shielded bearings is built for durability and low maintenance. The sealed bearing design prevents debris ingress and reduces internal friction, allowing for smoother rotation and extended motor life. This is especially valuable in outdoor flying environments where dust and vibration can compromise performance. By minimizing wear and supporting consistent shaft alignment, the bearings contribute to reliable operation across multiple flight sessions, making the motor a dependable choice for both casual and competitive pilots.

Yes. The Spektrum M-SPMXAM4770 electric upgrade for 20cc gas-to-electric conversions is specifically designed to replace combustion systems with clean, efficient brushless power. Its 450Kv rating and 5065 size class make it compatible with airframes originally built for 20cc gas engines. The motor supports 16x6 to 17x8 electric propellers and delivers up to 1200 watts of burst power, enabling equivalent or superior performance without the noise, fumes, or maintenance of fuel-based setups. For builders seeking a streamlined conversion process, the included prop adapter and mounting hardware simplify installation and alignment.
How does airflow-optimized cooling enhance performance?
The Spektrum 450Kv motor for sport and 3D aircraft with efficient cooling airflow is engineered to channel air through its housing, promoting thermal stability during high-load operation. This airflow design helps dissipate heat generated during extended throttle use, protecting internal components and preserving output consistency. For pilots flying aerobatic routines or long-duration missions, the cooling system ensures that the motor remains responsive and safe throughout the flight. Combined with brushless efficiency, this feature supports sustained performance without thermal stress or power degradation.
What integration benefits come with Smart ESC compatibility?
The Spektrum Avian motor for 5S–6S LiPo setups and Smart ESC compatibility is optimized for seamless pairing with Spektrum Smart Avian 100A ESCs. This integration enables telemetry feedback, adaptive timing control, and simplified setup for electric aircraft. The motor’s electrical specifications align with Smart ESC parameters, ensuring safe current handling and efficient power delivery. For users building Smart Technology-equipped models, this compatibility enhances system awareness and flight confidence, making the motor a strategic component in modern electric aircraft builds.
