At just £13.99, it represents outstanding value for a genuine manufacturer component that will keep your P-40 or compatible aircraft flying smoothly and reliably.

When you choose the FMS 10.5 x 7 3-Blade Propeller, you're investing in a component backed by FMS Hobby's reputation for quality and customer support. This propeller is compatible with RC aircraft that require this specific diameter and pitch combination, making it an ideal replacement for worn propellers or an upgrade for those seeking improved thrust characteristics. The three-blade design provides enhanced stability and smoother power delivery compared to two-blade alternatives, giving RC pilots in the UK access to professional-grade performance at an affordable price point.

Key Features

• 980mm Diameter with 7-inch Pitch — The 10.5 x 7 specification defines the propeller's aerodynamic characteristics, delivering optimised thrust and RPM performance for P-40B scale aircraft and compatible models. This combination ensures your RC aeroplane achieves the correct power-to-weight ratio for authentic, stable flight dynamics.
• Three-Blade Design — The three-blade configuration provides superior stability and smoother power delivery throughout the flight envelope compared to two-blade alternatives. This design characteristic is particularly beneficial for scale warbird pilots who value realistic handling characteristics and reduced vibration during sustained flight.
• P-40B Warbird Compatibility — Specifically engineered for the 980mm P-40B Warhawk and compatible RC aircraft platforms, this propeller delivers authentic performance characteristics for this iconic scale model. RC aeroplane enthusiasts appreciate propellers that maintain the authentic flying characteristics of their favourite vintage aircraft.
• Genuine FMS Manufacturing — Manufactured by FMS Hobby, a recognised leader in scale RC aircraft components, this propeller meets exacting quality standards and provides the reliability expected from an official factory component. FMS components are trusted by RC pilots across the UK for consistent performance and durability.
• Precision Engineering — The propeller is engineered with meticulous attention to blade balance and aerodynamic efficiency, ensuring smooth operation and reduced vibration during flight. Unbalanced propellers can cause flutter and premature wear on aircraft components, making precision manufacturing essential.
• RC Thrust Upgrade Option — For pilots seeking to enhance the climb performance and acceleration of their P-40 or compatible aircraft, this propeller delivers a meaningful thrust upgrade path. Swapping propellers is often the most cost-effective method to fine-tune your aircraft's performance characteristics without expensive motor or ESC changes.
• Direct FMS Compatibility — As an official FMS component, this propeller integrates seamlessly with FMS Hobby aircraft and the broader FMS ecosystem of RC aeroplane products. Using genuine manufacturer components ensures optimal fit, finish and flight performance.

Technical Performance

The FMS 10.5 x 7 3-Blade Propeller represents the confluence of aeronautical engineering principles and practical RC aircraft design. The 980mm diameter measurement establishes the propeller's reach and swept area, which directly influences the volume of air moved per revolution. The 7-inch pitch specification indicates the theoretical distance the propeller would advance through the air in one complete revolution if there were no slippage, and this characteristic is fundamental to determining RPM compatibility with your aircraft's motor and power system. Three-blade propellers like this model generate thrust more smoothly than two-blade designs, distributing aerodynamic loads across three surfaces rather than two, which results in reduced vibration, lower noise signatures, and less stress on aircraft structures during extended flight operations. This makes them particularly suitable for scale warbird aircraft where authentic, stable flight characteristics are prioritised. RC aeroplane pilots across the UK recognise that propeller selection is as critical as motor or battery choice, as the propeller is the interface between electrical power and actual thrust generation. The precision balance and aerodynamic profile of this FMS propeller ensure that airflow over the blade surfaces remains laminar and efficient throughout the flight envelope, translating available motor power into maximum useful thrust rather than wasted energy and vibration. For P-40B scale models and compatible aircraft, this propeller specification provides the optimal balance between climb performance, cruise efficiency, and altitude-holding capability.

Frequently Asked Questions

• What aircraft models is this FMS propeller compatible with? — This propeller is specifically engineered for the 980mm FMS P-40B Warhawk and other RC aircraft models that require a 10.5 x 7 propeller specification. The 980mm diameter and 7-inch pitch combination determines compatibility, so ensure your aircraft motor and power system support this specification before purchasing. If you're unsure whether your specific model is compatible, contact our RC Model Shop team who can advise on fitment.
• Is this a genuine FMS component? — Yes, this is a genuine FMS Hobby manufactured propeller, confirmed by the model number FMSPROP031 and official manufacturer branding. Purchasing from authorised retailers like RC Model Shop ensures you receive authentic components backed by FMS Hobby's quality standards and customer support, avoiding counterfeit alternatives that may perform poorly or fail prematurely.
• What is the difference between 3-blade and 2-blade propellers for RC aircraft? — Three-blade propellers, like this model, distribute aerodynamic loads across three surfaces rather than two, resulting in smoother thrust generation, reduced vibration, lower noise levels, and less structural stress on the aircraft fuselage and motor bearings. Two-blade propellers generate more peaked thrust pulses and typically produce higher noise signatures. For scale warbird aircraft like the P-40B, the three-blade design provides more authentic and stable flight characteristics.
• How often should I replace my RC aeroplane propeller? — Propellers should be inspected before each flight for damage, cracks, or nicks that could affect balance and aerodynamic efficiency. Replace your propeller whenever you notice visible damage, unbalance symptoms such as vibration during powered flight, or if performance seems degraded. Regular replacement of worn propellers is cost-effective insurance against more expensive motor or airframe damage caused by unbalanced or damaged blades.
• What does the 10.5 x 7 specification mean? — The first number (10.5) indicates the propeller diameter in inches, whilst the second number (7) represents the pitch in inches. This specification determines the propeller's swept area and theoretical forward distance per revolution, both critical factors in selecting a propeller that matches your aircraft's motor, power system, and desired performance characteristics. Always verify your aircraft specifications against this sizing before purchase.
• Will this propeller improve my P-40B aircraft performance? — If you're upgrading from a worn or damaged propeller, the FMS genuine component will restore full performance and flight characteristics. If you're upgrading from a different propeller specification, performance changes depend on the previous propeller's condition and characteristics. This propeller is the optimal specification for the 980mm FMS P-40B model, delivering the intended climb, cruise, and flight envelope performance that FMS engineers designed into the aircraft.
• Where can I buy an FMS propeller in the UK? — RC Model Shop is an authorised FMS Hobby retailer, offering genuine FMS components including this propeller with professional guidance and ongoing customer support. Shopping with authorised retailers ensures product authenticity, correct specifications, and access to expert advice if you have questions about compatibility or installation.
