Overview
The EFL 3.75 x 3 Propeller is a precision-engineered replacement propeller designed specifically for the ParkZone F-27Q Stryker Ultra Micro RC aircraft. This compact yet efficient propeller is an essential spare part for anyone operating ultra-micro RC aircraft in the UK, whether you're a seasoned RC enthusiast or discovering the world of small-scale flying for the first time. The F-27Q Stryker is renowned for its exceptional flight characteristics and durability, and maintaining genuine OEM components like this propeller ensures your aircraft continues to perform at its best.
Ultra-micro RC aircraft have revolutionised the hobby by making RC flying accessible, affordable and practical for enthusiasts with limited space. Unlike larger RC models that demand vast outdoor areas, the ParkZone F-27Q Stryker and compatible ultra-micro aircraft can be flown in parks, gardens and open spaces across the UK. This propeller is a direct replacement part that maintains the exact performance characteristics your aircraft was designed around, ensuring smooth, reliable flight every time you take to the air. Whether you're replacing a damaged propeller after a hard landing or simply maintaining spares for regular flying sessions, this genuine E-flite component is the smart choice for keeping your fleet airborne.
The 3.75 x 3 specification represents the propeller's diameter and pitch, carefully calculated to deliver optimal thrust and efficiency for ultra-micro electric powerplants. E-flite has engineered this propeller to work seamlessly with the motor and battery systems in the F-27Q Stryker, providing the perfect balance of thrust, efficiency and flight time. Investing in genuine OEM parts like this propeller protects your aircraft investment and ensures consistent, predictable performance flight after flight.
Key Features
- Genuine OEM Component — This propeller is a factory original part manufactured by E-flite and designed specifically for the ParkZone F-27Q Stryker Ultra Micro aircraft, ensuring perfect compatibility and performance that matches the aircraft's original specifications exactly.
- 3.75 x 3 Specification — The 3.75-inch diameter and 3-inch pitch combination has been engineered to deliver optimal thrust and fuel efficiency for ultra-micro electric motors, providing the ideal power-to-weight ratio for smooth, stable flight.
- Ultra-Micro Compatibility — Specifically engineered for ultra-micro aircraft, this propeller is lightweight and compact whilst maintaining sufficient blade strength to handle the demands of regular recreational flying and aerobatic manoeuvres.
- Direct Replacement Part — As a dedicated spare component, this propeller is an exact match for the original equipment, eliminating guesswork about compatibility and allowing you to quickly restore your aircraft to full flying condition after damage or wear.
- E-flite Quality Engineering — E-flite is a recognised leader in electric RC aircraft design and manufacturing, and this propeller reflects their commitment to quality, precision and reliability in every component they produce.
Technical Performance
The EFL 3.75 x 3 Propeller represents precision engineering specifically optimised for ultra-micro electric aircraft applications. The 3.75-inch diameter provides an effective sweeping area that generates sufficient thrust whilst remaining compact enough for the tight motor mounts and airframes characteristic of ultra-micro designs. The 3-inch pitch is engineered to allow the motor to reach optimal RPM whilst delivering smooth, controllable thrust across the flight envelope. Ultra-micro electric aircraft typically utilise small brushless outrunner motors in the 1000-3000 KV range, powered by single-cell or small multi-cell lithium polymer batteries. The propeller's design accounts for these relatively low power outputs, with blade geometry optimised to convert motor RPM into efficient lift and forward thrust. The lightweight construction minimises rotational mass, which is critical for ultra-micro aircraft where every gram affects flight performance and endurance. The propeller blade material and thickness have been carefully engineered to provide sufficient structural rigidity to handle normal flight loads whilst remaining flexible enough to absorb vibration and protect the motor from damage. This balance between strength and flexibility is essential for reliable performance across the operational envelope of the F-27Q Stryker, whether flying in calm conditions or navigating light wind. The propeller's aerodynamic profile has been tested and optimised to deliver smooth, efficient thrust generation with minimal vibration, contributing to the overall flight quality and stability that makes the F-27Q Stryker such a popular ultra-micro platform.

Frequently Asked Questions
- Is this propeller compatible with other Ultra Micro aircraft? — This propeller is specifically designed for the ParkZone F-27Q Stryker Ultra Micro aircraft. Whilst other ultra-micro models may use similar power plants and airframes, compatibility cannot be guaranteed. Always verify the part number against your aircraft manual before ordering. The ParkZone/E-flite compatibility ecosystem includes many models sharing common components, but each aircraft is engineered around specific prop specifications, so always confirm exact part numbers with your manual or our expert team.
- Why should I buy genuine OEM propellers rather than generic alternatives? — Genuine OEM propellers like this E-flite component are engineered specifically for your aircraft's motor, battery system and airframe. Generic propellers may have different pitch, diameter, balance or material specifications that can result in reduced efficiency, decreased flight time, excessive vibration, or even motor damage. The cost savings of a generic propeller are quickly offset by reduced flight performance and increased risk of mechanical failure. Genuine parts protect your investment and ensure reliable, consistent performance.
- What happens if my propeller is damaged? — Propellers are expendable components subject to wear, damage from hard landings, grass strikes and collisions. Having spare propellers on hand allows you to quickly return to flying after minor damage, minimising downtime. Always inspect your propeller visually before each flight for cracks, chips or warping. A damaged propeller can cause excessive vibration, reduce flight time and damage the motor shaft. Replace immediately if damage is visible.
- How often will I need to replace my propeller? — With careful flying and regular inspection, a propeller may last many flight hours. However, ultra-micro aircraft are often flown in environments where minor grass strikes and landing impacts occur. We recommend keeping spare propellers on hand for both the F-27Q Stryker and any other aircraft in your fleet, ensuring you can continue flying even if a propeller is damaged or requires replacement.
- What is the difference between this propeller and others available for Ultra Micro aircraft? — This propeller is engineered specifically for the ParkZone F-27Q Stryker's motor and airframe design. The 3.75 x 3 specification directly relates to the aircraft's power system optimisation. Other propellers with different diameter or pitch specifications will result in different thrust curves, motor loading and flight characteristics. Only genuine OEM propellers deliver the exact performance the aircraft was engineered to achieve.
