Key Features

• Double Dynamic Balance Technology — Both the rotor and complete motor assembly undergo dynamic balancing during manufacture. The rotor is balanced first, then the motor is tested under simulated operating conditions to perform a secondary dynamic balance check. This dual-stage process ensures extremely smooth operation with minimal vibration, which is critical for fixed-wing aircraft where unwanted vibration can affect flight stability, control response and overall flight quality.
• Superior Efficiency and Extended Runtime — The 4130SL delivers more than 2.5% higher efficiency compared to competing motors of equivalent specifications, meaning you extract more power from your battery charge. This translates directly to longer flight times and reduced heat generation during operation. The continuous running time is extended by more than 30% compared to competing motors, making this an economical choice for those who want to maximise airtime.
• Advanced Self-Cooling Rotor Design — The rotor incorporates a self-cooling structure that significantly improves heat dissipation during flight. This innovative design keeps the motor running cooler than conventional alternatives, which protects the motor's internal components and extends its operational lifespan. Better heat management also means the motor maintains peak performance for longer periods without thermal throttling or performance degradation.
• Patented Propeller Mount Locking System — The motor features an innovatively designed propeller mount locking mechanism (patent number 202311210278.7) that effectively prevents the propeller from flying off due to loose mounting nuts during flight. This safety-critical feature gives you confidence that your propeller will remain securely attached even under demanding flight conditions, eliminating a common failure mode that can result in lost aircraft and safety hazards.
• Diamond-Shaped Anti-Slip Propeller Seat — The propeller mounting seat employs a diamond-shaped anti-slip design that prevents the propeller from slipping or free-spinning on the shaft. This geometric design feature ensures positive engagement between motor shaft and propeller hub, maintaining critical power transmission and flight stability throughout your flight session.
• Premium Component Selection and Materials — The motor utilises a top-tier JNEH1200 iron core for the stator, which provides superior magnetic performance and longevity. The winding uses 200°C high-temperature resistant enamelled wire, allowing the motor to handle sustained high-power applications without insulation breakdown. International top-tier brand bearings (696ZZ specification) ensure smooth shaft rotation with minimal friction and wear, contributing to the motor's reliability and service life.
• N52SH Strong Magnetic Arc Design — The motor employs N52SH grade strong magnetic arc-shaped magnets that provide powerful torque delivery and consistent performance throughout the motor's operating range. This magnet selection ensures responsive throttle control and strong acceleration characteristics essential for dynamic fixed-wing flying.

This protective covering prevents accidental short circuits and provides durability against mechanical damage during installation and operation.
• Multiple Rotor Locking Designs — The rotor incorporates three separate locking mechanisms: copper pads, a circlip, and a bushing set screw. This redundant design philosophy prevents the rotor from loosening during operation, ensuring absolute reliability and consistency even under sustained high-power flight conditions. The multiple locking points significantly enhance overall motor reliability compared to single-lock designs.
• Multi-Purpose Design Flexibility — The motor can be configured with either standard or optional rear shaft propeller mounts, allowing adaptation to different aircraft designs and configurations. This versatility means a single motor type can serve multiple building projects without requiring alternative motor purchases.
• Lightweight Titanium Alloy Hardware — The mounting nuts and bracket screws are manufactured from titanium alloy rather than steel, reducing overall weight whilst maintaining structural integrity. In fixed-wing applications where every gram counts toward improving flight performance and battery efficiency, this material choice delivers measurable benefits.
• Modular and Easy-Maintenance Design — The motor features modular construction that allows straightforward disassembly for cleaning and maintenance. This design philosophy makes it practical to perform routine maintenance without specialised tools or technical expertise, extending the motor's service life and ensuring consistent performance season after season.
