Overview
The E-flite 4-Blade Propeller, 4.5 x 4.0 (model Z-EFLUP45404) is a genuine replacement component designed specifically for the UMX P-51 Voodoo ultra-micro RC aircraft. Whether you're an experienced RC pilot in the UK or just starting your journey into micro RC flying, having spare propellers on hand is essential for keeping your aircraft airborne. Ultra-micro RC aircraft like the P-51 Voodoo represent the cutting edge of compact RC engineering, delivering incredible scale realism and manoeuvrability in a package small enough to fly indoors or in confined spaces. This four-blade propeller is the ideal replacement when your existing prop needs maintenance or has suffered damage during normal flight operations.
Propeller selection is crucial to RC aircraft performance, and choosing the correct size and pitch ensures your UMX P-51 Voodoo operates at peak efficiency. The 4.5 x 4.0 specification denotes the propeller's diameter and pitch characteristics, which directly influence thrust, efficiency and flight characteristics. By selecting genuine E-flite replacement parts, you're investing in compatibility, reliability and the longevity of your ultra-micro RC aircraft. RC hobbyists across the UK trust E-flite components because they're engineered to exact standards and manufactured to the same specifications as original equipment.
This four-blade design offers improved performance characteristics compared to traditional two-blade propellers, particularly in delivering smooth, consistent thrust across a range of flight conditions. Whether you're performing aerobatic manoeuvres, cruising at steady speeds or practising scale-like flying, having quality spare propellers ensures you can keep flying without interruption. Stock this genuine E-flite propeller in your spares kit today and avoid frustrating downtime when accidents happen.

Technical Performance
The E-flite 4.5 x 4.0 four-blade propeller delivers the engineering precision that ultra-micro RC aircraft demand. Ultra-micro aircraft represent some of the most sophisticated RC technology available, combining lightweight construction with advanced materials and aerodynamic design to achieve flight performance that rivals full-size aircraft proportionally. The four-blade design of this propeller specifically enhances thrust characteristics across a broader speed range, providing smoother acceleration and more stable flight control inputs compared to traditional two-blade alternatives. The 4.5-inch diameter and 4.0-inch pitch specification have been engineered for the UMX P-51 Voodoo's motor and airframe design, ensuring that thrust generation matches the aircraft's weight, control surfaces and intended flight envelope. This propeller is manufactured using quality materials selected for their balance of durability, strength and lightweight properties—critical characteristics for ultra-micro aircraft where every gram affects performance. The precise blade geometry ensures minimal vibration during operation, which is essential for maintaining flight stability and camera smoothness if you're using your aircraft for aerial photography or video. Whether you're flying indoors in a gymnasium-sized space or outdoors in calm conditions, this propeller delivers the controlled power characteristics your UMX P-51 Voodoo requires for authentic, smooth and predictable flying.

Frequently Asked Questions
- Is the E-flite 4.5 x 4.0 propeller compatible with other ultra-micro RC aircraft? — This propeller is engineered specifically for the UMX P-51 Voodoo ultra-micro RC aircraft. While the size designation is 4.5 x 4.0, propeller compatibility depends on motor shaft diameter, mounting system and aircraft design. Always verify compatibility with your specific aircraft model before purchasing. If you're unsure whether this propeller will fit your RC aircraft, contact our knowledgeable team at RC Model Shop and we'll confirm compatibility for you.
- How often should I replace my propeller? — Propellers should be inspected before each flying session and replaced immediately if you notice cracks, chips, bends or excessive wear. Even minor damage can affect flight stability and efficiency. Regular inspection and timely replacement ensure optimal aircraft performance and safe flying. Many experienced RC pilots in the UK keep multiple spare propellers on hand to minimise downtime.
- Why choose four-blade propellers over two-blade designs? — Four-blade propellers deliver several performance advantages including improved thrust consistency, smoother acceleration, reduced vibration and more stable flight control response. The four-blade design distributes thrust across more blade area, resulting in gentler power delivery that's particularly beneficial for smooth scale flying and precise control. If your UMX P-51 Voodoo originally came with this propeller, the four-blade design was chosen to optimise your aircraft's flight characteristics.
- What is the difference between pitch numbers on propellers? — Propeller pitch (the second number in the specification) determines how far forward the aircraft moves with each complete propeller rotation. A 4.0-inch pitch means the propeller theoretically moves the aircraft 4 inches per revolution. Higher pitch values result in faster speed but require more motor power, whilst lower pitch values provide more thrust at the expense of top speed. The 4.0-inch pitch on this propeller has been selected specifically for the UMX P-51 Voodoo's motor and airframe to deliver balanced performance.
- How do I know if my propeller needs replacing? — Visual inspection is the first step—look for visible cracks, whitish stress marks, chips or bent blade edges. Even small cracks will spread during flight and compromise safety. Additionally, if your aircraft exhibits vibration during flight that wasn't present with a new propeller, replacement is recommended. Damaged propellers don't just reduce performance; they can cause mechanical stress on your motor and airframe.
- Can I use this propeller with different motors? — Propeller selection depends on multiple factors including motor KV rating, motor size, aircraft weight and intended flight characteristics. Whilst this propeller is designed for the UMX P-51 Voodoo's specific motor, using it with different motors without verification could result in motor overload, inefficient flight or unsafe operation. Always consult your aircraft manual or contact our team for motor compatibility confirmation.
