The SPM Brushless Motor 2840-3150Kv 6-Pole is a high-performance electric motor purpose-built for the Viper 64mm EDF jet platform. This brushless motor represents the pinnacle of electric ducted fan technology, delivering the responsiveness and power required for realistic jet aircraft simulation. Whether you're an experienced RC jet pilot looking to upgrade your existing Viper platform or exploring the exciting world of electric jet flight for the first time, this motor from Spektrum offers the precision engineering and reliability that serious RC enthusiasts demand. The 2840 size designation, combined with its 3150Kv rating and 6-pole configuration, creates an optimal power delivery profile specifically tuned for EDF jet applications across the United Kingdom and beyond.
Brushless motors have revolutionised the RC hobby, delivering superior efficiency, longer flight times, and more consistent performance compared to traditional brushed alternatives. The 3150Kv specification means this motor will produce approximately 3150 revolutions per minute under no-load conditions at 1 volt of applied electrical pressure, making it ideally suited to the demanding requirements of ducted fan propulsion. The 6-pole motor design contributes to smooth power delivery and reduced vibration, critical factors for maintaining stable flight characteristics in a high-speed jet platform. This is a genuine Spektrum component, ensuring compatibility with Spektrum's ecosystem of RC electronics and providing the quality assurance you expect from a leading manufacturer in the RC hobby.

Technical Performance
The SPM Brushless Motor 2840-3150Kv 6-Pole represents the engineering standard for modern electric ducted fan propulsion in the RC hobby. The 6-pole brushless configuration provides significantly smoother torque characteristics than lower-pole-count alternatives, resulting in more refined power delivery that translates to superior flight stability and control precision. The 3150Kv rating has been specifically selected to match the aerodynamic requirements and weight characteristics of the Viper 64mm EDF platform, ensuring you achieve the proper thrust-to-weight ratio needed for authentic jet-like performance including smooth climbs, sustained high-speed flight, and dynamic aerobatic capability. Brushless motor technology eliminates the maintenance burden of brush replacement whilst delivering superior energy efficiency, meaning more of your battery's stored energy converts to thrust rather than being lost as heat and friction. The motor's compact 2840 size allows installation within the tight confines of the EDF duct whilst providing ample power output, demonstrating the sophisticated engineering that makes modern electric RC jets viable as serious flying platforms. For UK pilots seeking to build or upgrade a Viper 64mm EDF jet, this motor provides the precise performance characteristics needed to unlock the full potential of this platform, delivering the rapid spool-up, smooth power delivery, and sustained thrust that define the electric jet flying experience.

Frequently Asked Questions
- What does the 3150Kv rating mean for my Viper 64mm EDF? — Kv stands for RPM per volt, meaning this motor will spin at approximately 3150 revolutions per minute when supplied with 1 volt of electrical power. On a typical 3S LiPo battery (11.1 volts nominal), the motor would theoretically spin at around 35,000 RPM under no-load conditions, though actual speeds will be lower under load. This Kv rating has been chosen specifically to match the Viper platform's requirements, delivering optimal thrust output without over-speeding or stalling the EDF fan.
- Is the 6-pole design better than other motor configurations? — The 6-pole brushless design offers superior performance compared to lower-pole alternatives because it produces smoother torque delivery and less vibration across the entire throttle range. In practical terms, this means your Viper 64mm EDF will respond more linearly to throttle input, climb more smoothly, and maintain better stability during high-speed flight and aerobatic manoeuvres, providing a more authentic jet-like flying experience.
- What battery should I use with this motor? — The appropriate battery type and cell count should be determined by your Viper 64mm EDF platform's specifications and the accompanying ESC you select. Typically, EDF motors in this class operate on 2S or 3S LiPo batteries, though you must verify your specific airframe's requirements as oversizing or undersizing the battery will compromise performance and potentially damage components.
- Do I need any additional electronics to make this motor work? — Yes, this motor component requires a compatible brushless ESC (Electronic Speed Controller) to regulate power delivery, an RC radio system with receiver to provide control input, and an appropriate LiPo or LiIon battery pack to supply electrical power. These components must be properly matched to each other and to the motor's specifications for safe, reliable operation.
- Is brushless technology worth the investment compared to brushed motors? — Absolutely. Brushless motors deliver significantly better energy efficiency, requiring less maintenance, generating less heat, and providing more consistent performance throughout their lifespan. In the context of electric RC jet flight, brushless technology is now the standard because it enables reliable sustained high-speed operation essential for convincing jet performance.
- How does this motor compare to other EDF options? — The 2840 size and 3150Kv rating combination makes this motor ideal for the Viper 64mm EDF platform specifically. Motors with different sizes or Kv ratings might fit physically but would deliver suboptimal performance—either insufficient thrust or excessive current draw. Using this motor ensures your Viper achieves the performance its design intended.
