Technical Performance

The FMS 11 x 5.5 propeller represents a carefully balanced engineering solution for mid-range RC aircraft performance. The 11-inch diameter provides sufficient blade surface area to generate adequate thrust for sustained flight, climb performance, and aerobatic manoeuvres, whilst the 5.5-inch pitch ensures that the propeller operates efficiently within the optimal RPM range of the motor systems fitted to the LED Firefly and 1100 F3A aircraft. The 2-blade design minimises rotational inertia, allowing for responsive throttle control and precise flight handling characteristics essential for F3A competition flying or advanced aerobatic training. The propeller's construction prioritises durability and consistent performance, with engineering designed to maintain balance and aerodynamic efficiency throughout its operational lifespan. Material quality and manufacturing tolerances ensure reliable engine coupling and vibration-free operation, critical factors that directly impact flight stability and aircraft longevity. For RC pilots operating their aircraft in UK weather conditions, the propeller's robust design provides confidence in consistent performance across varying atmospheric conditions.

Frequently Asked Questions

• Is the FMS 11 x 5.5 propeller suitable for both LED Firefly and 1100 F3A aircraft? — Yes, this propeller is specifically engineered and tested for both the FMS LED Firefly and 1100 F3A models. FMS has optimised the 11 x 5.5 specification to deliver perfect performance characteristics for both aircraft platforms, making it a versatile component for pilots operating either or both models.
• What does the 11 x 5.5 specification mean? — The first number (11) represents the diameter of the propeller in inches, whilst the second number (5.5) represents the pitch in inches. This means the propeller blade spans 11 inches and advances 5.5 inches forward with each complete rotation. This specific combination has been engineered to match the motor and airframe characteristics of your FMS aircraft.
• How often should I replace my propeller? — Propeller replacement intervals depend on usage frequency and flying conditions. You should inspect your propeller regularly for cracks, warping, or damage before each flight. If you notice any imperfections, replace the propeller immediately as a damaged propeller can cause vibration and aircraft instability. Even undamaged propellers should be replaced every 50-100 flight hours or if you notice changes in flight characteristics or increased vibration.
• Will this propeller work with other FMS aircraft models? — Whilst this propeller is specifically optimised for the LED Firefly and 1100 F3A, compatibility with other FMS models depends on the motor type and airframe design of the alternative aircraft. We recommend checking your aircraft's manual or contacting FMS support to confirm propeller compatibility before purchasing.
• Is this a genuine FMS component or a third-party alternative? — This is a genuine FMS manufacturing component, designated FMSPROP019 by the manufacturer. Purchasing genuine components ensures optimal compatibility, performance, and longevity compared to aftermarket alternatives.
• What is the difference between 2-blade and 3-blade propellers? — 2-blade propellers like this model offer excellent aerodynamic efficiency, simpler construction, and responsive handling characteristics ideal for F3A aerobatic flying. 3-blade propellers provide marginally higher thrust and smoother operation but at the cost of increased weight and mechanical complexity. For the LED Firefly and 1100 F3A, the 2-blade design is the manufacturer's recommended specification.
