Key Features

• High Power Output with Superior Torque Delivery — The motor is equipped with N48 strong magnetic arc magnetic steel design that provides maximum torque output, essential for aggressive climbing, rapid acceleration and sustained flight performance. The special propeller attachment mechanism ensures overall higher torque compared to conventional motor designs, allowing pilots to utilise larger and more efficient propellers safely.
• Exceptional Cooling and Heat Dissipation — The generous hollow cavity design, combined with the self-dissipating structure of the top cover, significantly increases cooling performance and extends motor lifespan. This engineering prevents thermal issues during extended flight sessions and ensures consistent power delivery throughout your flying day.
• Premium Materials for Long-Term Reliability — The motor utilises top-branded JNEH1200 silicon steel sheet at 0.2mm thickness, providing lower iron loss and superior efficiency. Combined with 180°C high-temperature resistant enameled wire in the stator coil, this motor is built to withstand demanding flight conditions and extended use without degradation.
• Optimised Rotor Design for Smooth Operation — The rotor has been engineered with high dynamic balance requirements, utilising excellent production and assembly dynamic balance technology with high-quality bearings and precision CNC machining. This results in extremely low rotor vibration, providing noticeably smoother operation and better overall aircraft stability during flight.
• Enhanced Rotor Reliability and Security — The multi-anti-loosening rotor design incorporates copper pads and retainer springs on the rotor shaft core, alongside bushings and set screws, ensuring the rotor remains securely fastened. This design philosophy significantly improves motor reliability and longevity, crucial for consistent performance across countless flight hours.
• Quality Phase Cable with Flexible Silicone Insulation — Featuring 18AWG silicone wire outlet construction, this cable is softer and easier to route than traditional straight outlet silicone wire, simplifying installation in tight airframe spaces and reducing installation time.
• Ideal Skywalker ESC Compatibility — This motor is a perfect complement to Hobbywing's Skywalker V2 ESC range (40-50A models), creating a harmonious control system that maximises performance and minimises compatibility issues.

Technical Performance

The Hobbywing Skywalker 2320SL 1250KV motor delivers impressive performance specifications optimised for fixed-wing RC aircraft. With a KV rating of 1250, no-load current of 2.3A at 14.8V, and resistance of 28.9 milliohms, this motor achieves a maximum continuous current of 50 amperes over 94 seconds, producing a remarkable 740 watts of continuous power. The motor utilises a 12N14P pole configuration (12 slots, 14 poles) and is designed to operate on 3-4S LiPo battery systems, providing flexibility for different aircraft designs and weight classifications. The 4mm shaft diameter accommodates standard RC aircraft propeller adapters, whilst the precision 684ZZ bearing (9mm outer diameter, 4mm inner diameter, 4mm width) ensures smooth, reliable rotation with minimal friction loss. At just 92 grams, the motor's compact dimensions of 28.8mm diameter by 54mm length make it suitable for installation in a wide variety of fuselage designs without excessive weight penalty. The 100mm 18AWG silicone phase cable provides excellent flexibility and current carrying capacity for reliable power delivery. Hobbywing's engineering delivers approximately 10% greater output power than competing motors with similar specifications, translating to superior climb performance, faster acceleration and improved responsiveness. The low 28.9 milliohm resistance minimises power losses and heat generation, allowing sustained high-performance flight without thermal concerns. Recommended propeller selection includes 9x4.5E, 9x6E, and 10x6E options for 3S LiPo systems, with 8x4E and 9x4.5E options available for 4S configurations, allowing pilots to optimise their setup for specific flying conditions and aircraft requirements.

Frequently Asked Questions

• Is the Hobbywing Skywalker 2320SL suitable for beginners learning RC aircraft flying? — Yes, this motor is suitable for RC enthusiasts with basic to intermediate flying experience. The 1250KV rating provides balanced power delivery without being overly aggressive, and compatibility with standard 3-4S LiPo batteries means the motor works with commonly available battery systems. However, beginners should ensure they have appropriate brushless ESC equipment and understand proper propeller selection for their aircraft weight and design.
• What battery specifications does this motor require, and will it work with my existing RC battery? — The Skywalker 2320SL is designed for 3-4S LiPo battery systems. A 3S LiPo battery provides 11.1V nominal voltage (approximately 12.6V fully charged), whilst a 4S LiPo provides 14.8V nominal (approximately 16.8V fully charged). The motor's no-load current specification is given at 14.8V (4S equivalent), meaning it will draw slightly less current from a 3S battery. You should verify your existing battery voltage before connecting; using battery voltages outside the 3-4S range may damage the motor or ESC.
• How does the Skywalker 2320SL compare to other motors in the Skywalker range? — Hobbywing manufactures the Skywalker series in three sizes: 2312, 2316, and 2320. The 2320 is the largest in the series, with dimensions of 28.8mm diameter by 54mm length and weighs 92 grams. The 2320SL 1250KV model specifically offers a mid-range KV rating within the 2320 size, making it suitable for moderate-speed aircraft. The 2320 range also includes 860KV and 1100KV variants offering lower speeds with higher torque, and the larger 2316 variant provides different performance characteristics. The 1250KV variant balances speed and torque effectively for general-purpose flying.
• What propeller sizes work best with the 1250KV Skywalker motor? — For 3S LiPo systems, recommended propellers include 9x4.5E, 9x6E, and 10x6E, providing different pitch options for various flight characteristics. For 4S LiPo systems, use 8x4E or 9x4.5E propellers. The propeller mounting utilises a 12mm diameter clip mounting with three M2.5 threads for secure attachment. Selection depends on your aircraft's weight, desired flight characteristics and battery capacity; lighter aircraft benefit from higher-pitch propellers whilst heavier designs may require lower-pitch, higher-torque options.
• Does this motor require a specific ESC, and can I use non-Hobbywing controllers? — Whilst not absolutely required, Hobbywing recommends the Skywalker V2 40A-50A ESC range, which is specifically tuned to work optimally with this motor. Any quality 50-ampere brushless ESC designed for aircraft use should function correctly with this motor, provided it supports 3-4S LiPo batteries and matches the current handling requirements. The motor's specifications are standard for brushless aircraft motors, so compatibility with alternative ESC brands is generally good.
• What aircraft types are suitable for the Skywalker 2320SL 1250KV motor? — This motor suits a wide range of fixed-wing RC aircraft including sport flyers, scale aeroplanes, trainers, high-wing models, and aerobatic aircraft in the appropriate weight range. The 1250KV rating is versatile, providing sufficient speed for rapid flight whilst maintaining adequate torque for climbing and acceleration. The motor's power output of 740 watts and sustainable 50-amp current draw makes it suitable for aircraft typically weighing 1-3kg, though exact suitability depends on your airframe design, wing loading and desired performance characteristics.
• How do I mount this motor to my RC aircraft airframe? — The motor features two mounting hole patterns. The propeller side utilises a 12mm diameter clip with three M2.5 threads for the propeller spinner attachment. The back mounting face features 16mm diameter holes (two M3 threads) or alternatively 19mm diameter holes (two M3 threads), allowing flexibility in mounting bracket design. You should consult your aircraft manual for specific mounting hardware and ensure secure installation to prevent vibration.
• What is the expected lifespan of the Skywalker 2320SL motor? — Hobbywing's engineering philosophy prioritises long-term durability. The premium materials (JNEH1200 silicon steel, N48 magnets, high-temperature enameled wire) and superior cooling design extend motor lifespan significantly compared to budget alternatives. With proper maintenance including regular cleaning, appropriate ESC settings, avoiding thermal overload, and using correctly-sized propellers, this motor should deliver reliable service for hundreds of flying hours.
