Technical Performance
The E-flite 5.75 x 2.50 Electric Propeller represents precision engineering optimised for small-scale electric RC aircraft. At 5.75 inches in diameter with a 2.50-inch pitch, this propeller is specifically designed to work in harmony with the brushless motor systems and lightweight airframes found in E-flite's UMX range. The propeller's dimensions have been carefully chosen to deliver efficient power conversion from the electric motor into controlled flight, providing the right balance between thrust generation and motor efficiency. The construction quality is characteristic of E-flite's reputation for reliability, with materials and manufacturing processes that have been proven across thousands of successful flights. This propeller works seamlessly with the brushless electric power systems found in UMX aircraft, which typically feature compact brushless motors paired with small-capacity LiPo batteries. The pitch angle and blade geometry are specifically optimised for the weight and drag characteristics of UMX platforms, ensuring predictable and responsive flight behaviour. Whether you're performing maintenance on an aircraft that has seen regular flying, or building up a spares collection for emergency replacements in the field, this genuine component will deliver the performance you expect from E-flite engineering. The simplicity of propeller replacement on UMX aircraft means that keeping several spares on hand is a practical approach to maximising your flying time without extended downtimes.

Frequently Asked Questions
- Is this propeller suitable for all E-flite UMX aircraft? — No, whilst this 5.75 x 2.50 propeller is compatible with several popular UMX models including the Yak 54, J-3 Cub, P3 Revolution, P-47 BL, Pitts S-1S and WACO variants, always verify compatibility with your specific aircraft model before purchasing. Different UMX models may require different propeller sizes, so checking your manual or product documentation is essential.
- What makes genuine E-flite propellers better than aftermarket alternatives? — Genuine OEM propellers are engineered to exact specifications by the aircraft manufacturer using materials, tolerances and aerodynamic optimisations proven through extensive testing. Aftermarket propellers often compromise on these specifications, which can result in reduced efficiency, unpredictable flight characteristics, increased motor strain, and potential safety issues. Using genuine E-flite parts guarantees your aircraft performs as designed.
- How often should I replace my propeller? — Propellers are consumable components that wear with use and are susceptible to damage from impacts and crashes. Inspect your propeller before each flying session for cracks, chips, warping or other damage. Replace it immediately if damage is detected. Even without damage, propellers gradually wear and can develop slight imbalances, so many experienced RC pilots replace them regularly to maintain optimal performance. Keeping spares on hand ensures you can always have a fresh propeller ready.
- Will this propeller fit other RC aircraft brands? — This is an E-flite specific component optimised for E-flite UMX models. Whilst the 5.75 x 2.50 size may physically fit some other small electric RC aircraft, we recommend using propellers specifically designed for your aircraft brand and model to ensure correct performance and safety. Using incorrect propellers can result in poor flight characteristics, excessive motor strain, or potential damage.
- How do I install this propeller? — Installation depends on your specific UMX model's motor and propeller attachment system. Typically propellers attach directly to the motor shaft using a small prop adapter and retaining nut. Always consult your aircraft's instruction manual for detailed installation steps. Most UMX aircraft feature tool-free or simple tool-required propeller installation, but procedures vary by model.
