Purchasing genuine OEM components like this SPM brushless motor is essential for maintaining the integrity and performance of your RC aircraft. When you choose authentic Spektrum replacement parts, you're investing in quality engineering and guaranteed compatibility with your existing system, which is particularly important for aircraft applications where reliability and consistency are paramount.
Key Features
- 4004 Motor Size — The 4004 dimensions indicate a compact, lightweight motor configuration that has been engineered specifically to fit within the Infusion 180 airframe whilst providing optimal weight distribution and balance for stable flight characteristics.
- 650Kv Rating — The 650Kv specification determines the motor's rotational speed relative to applied voltage, making this motor suitable for the Infusion 180's power system and delivering the appropriate thrust output needed for reliable flight performance in typical flying conditions.
- Brushless Technology — Brushless motors eliminate carbon brushes and commutators, resulting in significantly reduced electrical noise, lower maintenance requirements, longer operational lifespan, and more consistent power delivery compared to brushed alternatives available for RC aircraft.
- OEM Spektrum Component — This is a genuine factory part designed and manufactured to exact specifications by Spektrum, ensuring perfect compatibility with the Infusion 180 and maintaining the aircraft's performance characteristics as originally engineered.
- Direct Replacement Part — Whether you're rebuilding your aircraft after an accident, maintaining an existing system, or upgrading an older Infusion 180, this motor serves as a drop-in replacement that requires no modification or adaptation to your existing setup.
Technical Performance
The SPM 4004-650Kv brushless motor represents precision engineering designed for the demanding requirements of RC aircraft flight. The 4004 frame size has been specifically selected to provide an optimal balance between power output and weight, critical factors in aircraft performance where every gram impacts flight characteristics and battery endurance. At 650Kv, this motor will rotate approximately 650 revolutions per minute for every volt of battery voltage applied, making it well-suited to 2-cell and 3-cell LiPo battery systems commonly used in small-scale RC aircraft like the Infusion 180. Brushless motors operate through electronic commutation rather than mechanical brushes, eliminating friction points and contact wear, which translates to higher efficiency ratings and longer operational life compared to brushed alternatives. The motor's construction utilises high-quality materials and precision manufacturing tolerances to ensure consistent performance across multiple power cycles, with reliable torque delivery that supports stable climbing, level flight, and controlled descent. For RC aircraft applications, motor reliability is critical because any performance inconsistency during flight can affect handling characteristics and pilot control authority. This genuine Spektrum component has been tested and validated to perform reliably within the Infusion 180 system, maintaining the aircraft's intended flight envelope and responsiveness characteristics.
