Overview
The E-flite 14x7 Electric Propeller is a precision-engineered wooden propeller designed specifically for electric-powered model aircraft that demand reliable performance and consistent thrust delivery. This 14-inch diameter propeller with a 7-inch pitch is an ideal replacement or upgrade component for serious RC aircraft enthusiasts across the UK who are looking to optimise their flying experience. Whether you're operating a scale model aircraft or a performance-focused electric flyer, this propeller delivers the balanced combination of blade design and materials engineering that separates quality RC accessories from the rest.
The 14x7E designation indicates this propeller is engineered for electric motor systems, with particular compatibility designed around 6S LiPo battery setups that represent the sweet spot for many mid-size electric RC aircraft. If you're flying a Hangar 9 J-3 Cub 10cc model or similar class aircraft, the E-flite 14x7 Electric Propeller offers authentic performance characteristics that enhance flight duration, handling responsiveness and overall flight quality. This is a genuine E-flite component, manufactured to the strict quality standards that have made E-flite the trusted choice for RC model aircraft builders and flying enthusiasts across the UK and worldwide.
Purchasing replacement and upgrade propellers is a smart investment for any serious RC aircraft operator. Propellers inevitably experience wear during normal flight operations, and having quality spare propellers on hand means you can rotate them, inspect them for damage, and maintain your fleet of aircraft in peak flying condition. The E-flite 14x7 is the perfect addition to your RC spares collection, ensuring you're never grounded when a propeller reaches the end of its service life.
Key Features
- 14-Inch Diameter Design — The 14-inch diameter provides optimal blade surface area for generating smooth, efficient thrust across the RPM range that electric motors deliver, making it suitable for aircraft that require balanced lift and handling characteristics throughout flight operations.
- 7-Inch Pitch Engineering — The 7-inch pitch is carefully calculated to work in harmony with electric motor systems, offering an effective balance between thrust delivery and mechanical efficiency, which translates to better flight times and more responsive aircraft handling.
- 14x7E Electric Classification — The 14x7E designation confirms this propeller is optimised for electric power systems, distinguishing it from petrol or nitro propellers and ensuring full compatibility with electric motor setups and 6S LiPo battery configurations.
- Wooden Construction — Traditional wooden propeller construction provides a proven combination of strength, weight efficiency and vibration damping characteristics that synthetic materials struggle to match, resulting in smoother operation and better overall flight quality.
- 6S LiPo Compatibility — Specifically engineered for use with 6S LiPo batteries, this propeller is optimised to operate within the voltage and power delivery characteristics that 6-cell lithium polymer batteries provide, ensuring peak performance and longevity.
- Hangar 9 J-3 Cub 10cc Certified — This propeller is designed with specific compatibility for the Hangar 9 J-3 Cub 10cc model, meaning it has been engineered and tested to deliver optimal performance characteristics for this aircraft class without modification.
- Premium E-flite Manufacturing — E-flite is recognised across the RC hobby community as a manufacturer of dependable, high-quality components, and this propeller carries that same reputation for build quality and reliable performance season after season.
Technical Performance
The E-flite 14x7 Electric Propeller represents thoughtful engineering applied to one of the most critical components in electric RC aircraft operation. The 14-inch diameter and 7-inch pitch combination creates a blade geometry that has been refined through extensive testing with electric motor systems, particularly those powered by 6S LiPo batteries which deliver 22.2 volts nominal output. The wooden construction material is not simply chosen for tradition; timber offers superior damping characteristics compared to composite or plastic propeller options, meaning vibration is absorbed and dissipated rather than transmitted back into the airframe, ultimately resulting in smoother flight characteristics and reduced structural stress on mounting points and bearings. The pitch angle is engineered to strike a balance between achieving adequate thrust for reasonable climb rates whilst maintaining sufficient blade efficiency to maximise flight duration from your battery pack. This propeller is manufactured to stringent tolerances that ensure both blade halves are precisely matched in weight and pitch angle, eliminating the vibration and handling issues that can result from poorly balanced propellers. For operators flying RC aircraft in the UK, reliability and consistent performance are paramount given our climate and flying conditions, and the E-flite 14x7 delivers exactly that through proven design and quality manufacturing standards.

Frequently Asked Questions
- What size is the E-flite 14x7 Electric Propeller and what does 14x7E mean? — The propeller features a 14-inch diameter and 7-inch pitch, with the 'E' designation confirming it is engineered specifically for electric motor systems rather than petrol or nitro engines. The 14-inch diameter determines the overall blade length from tip to tip, whilst the 7-inch pitch indicates how far the propeller advances through the air during one complete rotation.
- What battery does this propeller need? — The E-flite 14x7 Electric Propeller is designed for use with 6S LiPo batteries, which deliver 22.2 volts nominal voltage and are the standard power source for mid-size electric RC aircraft in this performance class. Your electric motor and ESC must also be rated for 6S LiPo operation for safe and optimal performance.
- Is this propeller compatible with my aircraft? — This propeller is certified for use with the Hangar 9 J-3 Cub 10cc model aircraft. If you operate a different aircraft model, you should verify compatibility by checking your aircraft documentation or consulting with RC hobby specialists to ensure proper fit and performance.
- Why would I need a replacement propeller? — Propellers are wear items in RC flight operations. They endure significant mechanical stress during flight, and even minor impacts or rough landings can cause damage, stress fractures or blade erosion that degrades performance. Having quality replacement propellers ensures you can keep your aircraft in the air and maintain a fleet in top condition for optimal flying sessions.
- Is wooden construction better than composite propellers? — Wooden propellers offer superior vibration damping compared to synthetic materials, resulting in smoother flight characteristics and reduced stress on aircraft components. They are the choice of experienced RC pilots who value reliability and flight quality, though they do require slightly more careful handling and storage compared to composite alternatives.
- How do I know if my propeller needs replacement? — Inspect your propeller regularly for visible cracks, splintering, dents, or irregular blade shapes. If you notice increased vibration during flight, reduced climb performance, or longer flights taking shorter battery discharge cycles, your propeller may be fatigued and should be replaced with a fresh E-flite unit for optimal performance and safety.
