Key Features
- Correct Size Specification — The 11 X 5.5 dimension ensures you are fitting the exact propeller your RC aircraft manufacturer specifies, which is critical for maintaining proper aerodynamic balance, thrust characteristics and safe flight behaviour.
- Genuine E-flite Quality — As an original E-flite component, this propeller is manufactured to the same standards as the propeller that came with your aircraft, guaranteeing compatibility and performance reliability.
- Simple Replacement Solution — This spare propeller offers an easy way to keep your aircraft flying when your original propeller becomes damaged, worn or lost, without needing to source third-party alternatives or compromise on quality.
- Standard Fitment Part — Classified as a standard part rather than an optional upgrade, this propeller is the direct replacement your model expects, making installation straightforward and confidence-assured.
- Compact and Portable — Propellers are lightweight and compact, making them ideal to carry in your RC flying kit or spare parts box wherever you fly.
Technical Performance
The E-flite Propeller 11 X 5.5 is engineered to deliver the aerodynamic characteristics required by aircraft designed for this size specification. The 11-inch diameter and 5.5-inch pitch combination is optimised for efficient power conversion in electric-powered RC aircraft, providing a balance between thrust generation and power consumption. This propeller size is commonly used in sport-flying and recreational applications, where consistent, predictable performance is valued. The construction meets E-flite's quality standards, ensuring durability through normal RC flying use. Always follow your model manufacturer's guidance regarding propeller selection, as using the correct size is essential for maintaining the performance envelope and handling characteristics that your aircraft was engineered to deliver. Using an incorrectly-sized propeller can result in reduced efficiency, overloading of the motor or ESC, poor handling, or potential safety issues during flight.

Frequently Asked Questions
- What does the 11 X 5.5 size mean on an RC propeller? — The first number (11) refers to the diameter of the propeller in inches, while the second number (5.5) represents the pitch in inches. Pitch is the theoretical distance the propeller would advance through the air in one complete revolution. This 11 X 5.5 combination is optimised for efficient operation in electric-powered RC aircraft of certain sizes and power ratings.
- Is this the correct propeller for my E-flite aircraft? — This propeller is a standard fitment for the E-flite Slow Ultra Stick 1.2m BNF Basic. However, you should always verify the propeller size specified in your aircraft's manual or documentation before purchasing. Using the incorrect propeller size can affect performance and safety.
- What happens if I use the wrong propeller size on my RC aircraft? — Using an incorrectly-sized propeller can cause your motor or ESC to work harder than designed, reducing flight time, increasing power consumption, and potentially causing overheating or damage. It can also result in poor flight characteristics, reduced control response, and safety hazards. Always follow the manufacturer's specifications for your specific aircraft.
- How long will a propeller last? — The lifespan of a propeller depends on how frequently you fly and how carefully you handle landings and ground operations. Regular inspection for cracks, splits, or damage is recommended. Many RC pilots keep spare propellers on hand to ensure they can continue flying if a propeller becomes damaged during a flight session or hard landing.
- Do I need any special tools to install this propeller? — Installation depends on your specific aircraft model. Some propellers use a simple push-fit hub, whilst others may require a small wrench to secure a retaining nut. Refer to your aircraft's assembly or maintenance guide for installation instructions specific to your model.
- Can I use this propeller on other RC aircraft brands? — Propeller fitment is aircraft and motor-specific. Just because a propeller is 11 X 5.5 does not guarantee it will fit another brand's aircraft or work safely with different motor and ESC combinations. Always verify that an 11 X 5.5 propeller is the correct specification for your aircraft before use.
