FMS 12 x 6 2-Blade Propeller for RC Sailplane Aircraft FMSPROP042

Overview

The FMS 12 x 6 2-blade propeller is a precision-engineered replacement and upgrade component designed specifically for FMS RC model aircraft, particularly the popular 2300mm scale gliders and motorised sailplanes such as the Fox, ASK23, and ASW28. This high-quality propeller represents an excellent investment for RC enthusiasts across the UK who demand reliable performance and improved efficiency from their RC aircraft. Whether you are flying competitively, enjoying weekend flights at your local RC club, or simply expanding your spare parts collection, this propeller delivers the consistency and quality that serious RC flyers expect.

Built to exacting FMS standards, this 2-blade propeller has been specifically matched to the 2300mm airframe dimensions and weight characteristics of these popular sailplane models. For UK-based RC hobbyists, having quality spare propellers on hand is essential—whether you need a replacement after a landing mishap, want to experiment with different performance characteristics, or simply need backup components for reliability during important flying sessions. The 12 x 6 specification indicates a 12-inch diameter with a 6-inch pitch, making this an ideal match for the moderate power demands and flight characteristics of these efficient glider designs.

FMS, a recognised manufacturer in the RC hobby space, has engineered this propeller to optimise the balance between thrust efficiency and smooth, quiet operation. The 2-blade design is characteristic of high-efficiency sailplane propellers, offering excellent climb performance whilst maintaining the fuel efficiency and lightweight characteristics essential for sustained gliding flight.

Key Features

• Perfect Fit for 2300mm Models — This propeller has been specifically engineered for FMS 2300mm scale aircraft, including the Fox, ASK23, and ASW28 models, ensuring perfect compatibility and optimal performance without any modification required to your aircraft.
• 12 x 6 Specification — The 12-inch diameter and 6-inch pitch combination provides an ideal balance of thrust production and rotational speed, optimised for the power systems typically found in these glider-class aircraft, ensuring efficient climb and sustained flight performance.
• 2-Blade Design — The two-blade configuration is purpose-designed for high-efficiency flight, offering reduced rotational noise compared to multi-blade alternatives whilst delivering excellent power absorption characteristics and reliable thrust development across the flight envelope.
• Premium Construction Quality — Built to FMS manufacturing standards, this propeller demonstrates the quality and precision expected of genuine OEM components, ensuring consistent performance flight after flight and minimising vibration that could affect flight smoothness or aircraft longevity.
• Replacement and Upgrade Option — Whether you need a spare propeller following a landing incident, want to refresh worn components, or are building a comprehensive spare parts kit for reliability, this genuine FMS propeller is an essential addition to any RC aircraft enthusiast's inventory.

Technical Performance

The FMS 12 x 6 2-blade propeller represents a carefully engineered solution for improving RC model aircraft efficiency and flight characteristics. The 12-inch diameter provides substantial thrust absorption capability whilst the 6-inch pitch ensures that motor RPM remains within optimal ranges, preventing over-revving and maximising power system longevity. For 2300mm scale glider aircraft—whether motorised sailplanes or powered slope soarers—this propeller size is recognised as a standard that balances climb performance, cruise efficiency, and overall flight duration. The 2-blade design is particularly suited to electric motor installations where smooth, vibration-free operation is paramount; the reduced blade count minimises gyroscopic effects whilst maintaining excellent thrust characteristics across the range of flight speeds these aircraft encounter. The propeller's construction quality ensures that it maintains dimensional accuracy and blade tracking consistency through hundreds of flight hours, reducing the vibration and noise that can degrade flying experience and contribute to premature wear on motor bearings and airframe structures. For UK-based RC aircraft operators, having quality spare propellers ensures that minor incidents need not interrupt flying sessions—a simple propeller swap can have you back in the air within minutes.

Frequently Asked Questions

• Is this propeller compatible with my FMS RC aircraft? — This propeller is specifically designed for FMS 2300mm scale models including the Fox, ASK23, and ASW28. If your aircraft is one of these models, this propeller will provide perfect fit and optimal performance. For other FMS models, we recommend checking the aircraft manual or contacting our team to confirm compatibility.
• What are the advantages of a 2-blade propeller over other designs? — The 2-blade configuration offers several advantages including reduced rotational noise, lower gyroscopic effects, and excellent efficiency—particularly important for sailplane and glider-class aircraft where smooth, quiet operation enhances the flying experience and maximises flight duration. The simpler blade structure also contributes to reliable, vibration-free operation.
• How often should I replace my propeller? — Propellers should be inspected regularly for blade damage, cracks, or deformation. With normal use, a quality propeller like this FMS component should provide hundreds of flight hours. However, any visible damage, nicks to the leading edge, or loss of blade tracking should result in immediate replacement to prevent vibration, noise, and potential safety issues.
• What motor and ESC do I need for this propeller? — The FMS 2300mm aircraft models this propeller is designed for typically use brushless electric motors in the range of 35-65kV and standard ESCs suitable for sailplane and glider applications. Consult your aircraft manual for the specific motor and ESC recommendations, as these vary depending on your exact model and intended use.
• Can I use this propeller on other aircraft brands? — Whilst the 12 x 6 2-blade size is a common specification used across various RC aircraft, this propeller has been engineered specifically for FMS 2300mm models. Using it on other brands or sizes of aircraft may result in suboptimal performance or compatibility issues. We recommend using manufacturer-specified propellers for best results.
• Is this suitable for beginners? — Propeller replacement is a straightforward task suitable for all experience levels, and this FMS propeller will work seamlessly as a replacement component on compatible models. However, aircraft operation requires appropriate training and experience—we recommend that beginners start with RTR (Ready to Run) aircraft kits that include full instructions and support.
• How does propeller pitch affect performance? — The 6-inch pitch on this propeller means the blade twists such that theoretically the propeller would advance 6 inches per complete rotation. Higher pitch propellers increase speed but reduce climbing ability, whilst lower pitch propellers improve climb. The 6-inch pitch on this component is optimised for the power systems and flying characteristics typical of FMS 2300mm glider aircraft, providing excellent all-around performance.
