Key Features

• Powerful Motor Design — The Skywalker 2312SL delivers significantly more output power than competing motors of the same specification class, with approximately 10% additional power output that translates directly into improved climb rate, acceleration and overall flight performance for your RC aircraft.
• Special Propeller Attachment — The motor features a specially engineered propeller mounting system that ensures overall higher torque delivery, allowing your RC aeroplane to achieve better thrust characteristics and more efficient power transmission from the battery to the prop.
• N48 Magnet Technology — Equipped with premium N48 strong magnetic arc magnetic steel design, this motor maximises torque output, giving your fixed-wing RC model the responsive power delivery needed for precise control and aggressive manoeuvres.
• Exceptional Cooling Performance — A generous hollow cavity design, combined with the self-dissipating structure of the top cover, significantly increases cooling capacity and heat dissipation. This engineering ensures the motor can handle sustained high-power operations without excessive heating, dramatically extending the lifespan of the motor even during demanding flying sessions.
• Premium Construction Materials — The motor utilises top-branded JNEH1200 silicon steel sheet at just 0.2mm thickness, which provides lower iron loss and improved efficiency. The stator windings use 180°C high-temperature-resistant enameled wire, enhancing overall heat resistance and reliability under demanding conditions.
• Optimised Rotor Running — The rotor has been meticulously designed with excellent production and assembly dynamic balance technology, utilising high-quality bearings and high-precision CNC machining. This ensures extremely low rotor vibration, delivering noticeably smoother operation and reducing the feedback vibrations that can affect flight control precision.
• Multi-Anti-Loosening Rotor Design — The rotor shaft incorporates copper pads, retaining rings, bushings and set screws that work together to secure the rotor effectively. This multi-stage securing system dramatically improves motor reliability and prevents the catastrophic failures caused by rotor slippage or loosening during flight.
• Flexible Silicone Cable Outlet — Rather than rigid straight outlets, this motor features a flexible silicone wire outlet that is softer and significantly easier to route through tight fuselage spaces, simplifying installation in confined RC aircraft designs.
• Ideal Complement to Skywalker ESCs — This motor is specifically designed to work seamlessly with the Skywalker ESC ecosystem, providing pilots with a perfectly matched, integrated power system that maximises efficiency and reliability.
• 18AWG Silicone Phase Cable — The included 100mm 18AWG silicone phase cable provides excellent current handling capability whilst remaining flexible for easy installation in your RC airframe.

Technical Performance

The Hobbywing Skywalker 2312SL 1250KV brushless outrunner motor delivers impressive technical specifications designed specifically for fixed-wing RC aircraft applications. Operating at 1250KV, this motor spins at 1,250 revolutions per minute per volt of input, making it ideally suited for 3S and 4S LiPo battery configurations. The motor features a 12N14P configuration (12 poles on the stator, 14 poles on the rotor), which provides excellent torque characteristics and smooth power delivery. With a maximum continuous current rating of 38 amperes sustained for 35 seconds, the motor generates a maximum continuous power output of 563 watts, providing substantial thrust for medium-sized RC aeroplanes. The no-load current consumption of just 1.5 amperes at 14.8 volts demonstrates exceptional efficiency, ensuring that your battery capacity is used primarily for generating thrust rather than being wasted as heat. The motor's internal resistance of 51.6 milliohms is precisely engineered to optimise power delivery whilst minimising heat generation. Measuring 28.8mm in diameter and 46mm in length, this compact motor provides an excellent power-to-size ratio, making it suitable for a wide variety of airframe designs. The 4mm shaft diameter accommodates standard propeller adapters, whilst the dual 684ZZ ball bearings (9mm outer diameter, 4mm inner diameter, 4mm width) ensure smooth, long-lasting rotation with minimal friction. Weighing just 65 grams, the motor adds minimal weight to your RC aircraft whilst delivering maximum performance. The motor is recommended for use with Skywalker V2 30A-40A ESCs, and compatible with 3-4S LiPo batteries. For 3S configurations, the motor performs excellently with 8x6E, 9x4.5E and 10x6E propellers, whilst 4S users should select 8x4E or 8x6E props. The 18AWG phase cable extends 100mm from the motor, providing sufficient length for most airframe installations. The motor features M2.5 threads on the 12mm propeller mounting hole (3 mounting points) and M3 threads on the 16mm and 19mm motor mounting bases (2 mounting points each), allowing secure installation in virtually any RC airframe design.

• Is the Skywalker 2312SL suitable for beginners? — Yes, this motor is absolutely suitable for RC beginners. It is straightforward to install, compatible with widely available 3S and 4S LiPo batteries, and works seamlessly with affordable Skywalker V2 ESCs. The reliable, smooth operation makes it ideal for learning to build and fly RC aircraft without complexity or performance unpredictability.
• What battery does this motor need? — The Skywalker 2312SL 1250KV is recommended for 3S or 4S LiPo battery configurations (11.1V or 14.8V nominal). A typical setup might use a 1500-2200mAh 3S LiPo or a 1500-2000mAh 4S LiPo, depending on your aircraft weight and desired flight duration. Never attempt to use this motor with anything other than LiPo batteries, as other chemistries will not provide adequate power or current delivery.
• What propeller sizes work with this motor? — For 3S LiPo setups, use 8x6E, 9x4.5E or 10x6E propellers. For 4S configurations, select 8x4E or 8x6E propellers. These recommendations ensure optimal performance and prevent damage to the motor from overload. Always consult your airframe manufacturer's recommendations and balance your propeller before flight.
• How does the Skywalker 2312SL compare to other 1250KV motors? — The Hobbywing Skywalker 2312SL achieves approximately 10% more output power than comparable competing motors with identical specifications. This performance advantage comes from precision engineering, superior materials (JNEH1200 silicon steel and N48 magnets), optimised heat dissipation and exceptional rotor balancing. You'll experience noticeably better climb rate, acceleration and overall responsiveness compared to generic alternatives.
• What ESC should I use with this motor? — Hobbywing recommends the Skywalker V2 30A-40A ESC for this motor. This creates a perfectly matched system optimised for performance and reliability. Using the recommended ESC ensures warranty validity, optimal efficiency and seamless integration.

The premium materials, superior bearing quality, excellent cooling system and robust rotor securing design all contribute to extended lifespan. Regular inspection, keeping the motor clean and avoiding water immersion will maximise longevity.
• What makes the cooling system so effective? — The motor features a generous hollow cavity design combined with a self-dissipating top cover structure. This engineering allows airflow to circulate through the motor, rapidly removing heat generated during operation. The thin 0.2mm JNEH1200 silicon steel sheet further reduces iron losses that would otherwise create additional heat, ensuring sustained high-power operation without thermal problems.
• Is this motor suitable for high-altitude flying? — Yes, the Skywalker 2312SL is suitable for high-altitude applications. The efficient design and excellent cooling mean the motor maintains performance even as atmospheric density decreases with altitude. However, ensure your battery provides adequate current at altitude and that your propeller choice is optimised for the thinner air conditions you'll encounter.
• Can this motor be used in saltwater environments? — The Skywalker 2312SL is not recommended for saltwater exposure. The motor's bearings, electrical contacts and metal components will corrode if exposed to salt spray or seawater. Use this motor exclusively in freshwater or terrestrial applications, and rinse thoroughly with fresh water immediately after any freshwater exposure.
