Key Features
- 3730 Motor Frame Size — The 3730 frame designation indicates a motor with a 37mm diameter stator, which provides an excellent balance between power output and weight efficiency, making it ideal for 1.5m aircraft and similar-sized RC planes where weight management is crucial for flight performance.
- 650Kv Rating — The 650Kv specification means the motor will spin at approximately 650 revolutions per minute for every volt of input supplied, making this rating perfect for mid-range propeller applications and providing optimal thrust characteristics for cruising, aerobatic flight, and general-purpose RC aviation.
- 14-Pole Configuration — The 14-pole motor design delivers smoother, more consistent power delivery compared to lower pole count alternatives, resulting in reduced vibration, improved efficiency, and more predictable flight characteristics that pilots appreciate during all phases of flight.
- Brushless Technology — Unlike traditional brushed motors, the brushless design eliminates carbon brush wear, reducing maintenance requirements and extending the operational lifespan of your motor significantly, whilst improving overall efficiency and power delivery consistency.
- OEM Specification Motor — This motor is the exact factory-specified component for the E-flite EC-1500 1.5m airplane, ensuring perfect compatibility, optimal performance characteristics, and reliable integration with your existing airframe and electronic components.
- Proven Spektrum Quality — Spektrum is an authorised manufacturer recognised throughout the RC hobby for producing precision-engineered components that meet exacting performance standards, and this motor maintains that tradition of reliability and consistent performance.
Technical Performance
The Spektrum 3730-650Kv 14-Pole brushless motor represents the pinnacle of electric propulsion technology for RC aircraft in this performance class. The 3730 frame size provides an optimal power-to-weight ratio essential for 1.5m aircraft, where every gram matters for flight characteristics and battery efficiency. The 650Kv rating positions this motor in the sweet spot for general-purpose flying, delivering sufficient power for sustained flight, aerobatic manoeuvres, and responsive control without excessive current draw that would rapidly deplete your battery pack. The 14-pole stator configuration is particularly noteworthy, as this design choice results in significantly smoother commutation compared to 12-pole alternatives, meaning you'll experience less vibration transmitted through the airframe, more consistent thrust delivery, and superior overall flight characteristics. The brushless architecture eliminates the carbon brushes and commutators found in brushed motors, which means no brush dust accumulation, no periodic maintenance requirements, and dramatically extended operational lifespan. This motor is engineered to work seamlessly with appropriate brushless ESCs, lithium polymer (LiPo) battery packs in suitable voltage configurations, and standard RC aircraft propellers matched to the 650Kv specification. The precision construction ensures concentricity and balance that minimises vibration and ensures reliable operation across extended flight sessions. Whether you're replacing a worn motor or upgrading your EC-1500 platform, this brushless motor delivers the performance consistency that makes it the OEM choice for this airframe.
