Overview
The E-flite Prop and Spinner 130 x 70 (2): UM 4-Site/Champ (Model Z-EFL9051) is an essential replacement propeller and spinner set designed specifically for ultra-micro RC aircraft enthusiasts in the UK. This genuine E-flite component is engineered to deliver reliable performance for the HobbyZone Champ and other compatible ultra-micro airframes, making it the perfect choice for pilots who demand quality and consistency from their RC hobby equipment. Whether you're a seasoned RC flyer looking to maintain peak performance or a beginner discovering the world of micro RC aircraft, this propeller set ensures your aircraft operates at its best.
Propellers are one of the most frequently replaced components in any RC aircraft, as they endure considerable stress during flight operations and can suffer damage from landings, collisions, or normal wear. Having a spare set of high-quality propellers on hand is essential for serious RC pilots in the UK who want to minimise downtime and keep their aircraft flying consistently. The E-flite Prop and Spinner 130 x 70 set represents genuine manufacturer engineering, designed and tested specifically for use with the HobbyZone Champ and other compatible ultra-micro platforms.
This product is ideal for RC enthusiasts who operate their aircraft regularly and need reliable replacement parts sourced from an authorised retailer. The combination of genuine E-flite manufacturing quality and proven compatibility makes this an intelligent purchase for anyone invested in maintaining their RC aircraft in peak flying condition.
Key Features
- Genuine E-flite Manufacturing — This propeller and spinner set is produced by E-flite, the respected manufacturer of ultra-micro RC aircraft components, ensuring you receive parts engineered to the same exacting standards as your original equipment. Genuine parts guarantee optimal fit, balance and performance.
- Two-Blade Configuration — The two-blade design provides the ideal balance of efficiency and reliability for ultra-micro aircraft like the HobbyZone Champ, delivering smooth, predictable flight characteristics and reliable thrust generation across a range of flight conditions.
- 130 x 70mm Dimensions — The 5.1 x 2.75 inch (130 x 70mm) size is precisely engineered for ultra-micro platforms, providing the correct pitch and diameter to match the performance envelope of your aircraft and the power delivery characteristics of compatible micro motors.
- Integrated Spinner — The package includes a matching spinner that houses the propeller hub assembly, creating a finished, professional appearance whilst serving the functional purpose of directing cooling air and protecting the drive system components during flight operations.
- Direct Replacement Component — This set is specifically designed as a drop-in replacement for original equipment on HobbyZone Champ and Ultra Micro 4-Site aircraft, eliminating compatibility guesswork and installation complications. The part replaces the legacy PKZUP1002 component.
- Durable Plastic Construction — The propeller blades are manufactured from reinforced plastic, a material choice that balances strength, weight and cost-effectiveness whilst providing adequate durability for typical RC flying scenarios and absorbing impact energy during minor contact incidents.
Technical Performance
The E-flite Prop and Spinner 130 x 70 represents carefully engineered ultra-micro RC aircraft propulsion equipment designed to deliver reliable performance in the specific power and speed envelope of ultra-micro airframes. The 130 x 70mm (5.1 x 2.75 inch) propeller dimensions are calculated to work harmoniously with the lightweight micro motors fitted to aircraft like the HobbyZone Champ, a platform that typically operates with brushed electric motors of modest power output and 1S LiPo battery systems. The two-blade configuration has been proven through extensive real-world testing to deliver smooth, efficient thrust generation, predictable handling characteristics, and reliable performance across a wide range of flight conditions from gentle thermal soaring to more spirited aerobatic manoeuvres. The plastic construction, whilst light enough to minimise rotating mass and its associated inertial demands on the motor, remains robust enough to withstand the stresses of normal flight operations and minor contact with terrain during landing. The integrated spinner design ensures proper airflow management around the motor and gearbox assembly, critical for effective cooling of these compact power systems during extended flight sessions. This propeller and spinner combination has been comprehensively tested by E-flite engineers and proven compatible with the HobbyZone Champ platform, making it a trusted replacement choice for UK RC enthusiasts who demand reliability and performance consistency.

Frequently Asked Questions
- What aircraft is this propeller compatible with? — The E-flite Prop and Spinner 130 x 70 is specifically engineered for use with the HobbyZone Champ and other Ultra Micro 4-Site aircraft platforms. It serves as a direct replacement for the legacy PKZUP1002 component, ensuring seamless compatibility and performance.
- Why should I buy genuine E-flite replacement propellers rather than cheaper alternatives? — Genuine E-flite components are engineered and tested specifically for your aircraft platform, guaranteeing optimal fit, balance, weight distribution and aerodynamic performance. Genuine parts ensure your aircraft handles as designed and performs reliably, whilst cheap alternatives may introduce vibration, imbalance or incompatibility issues that compromise safety and flying enjoyment.
- How often do I need to replace my propeller? — Propeller replacement frequency depends on your flying habits, landing technique and whether the propeller sustains damage during operations. Many active flyers keep several spare propeller sets on hand to minimise downtime when damage occurs. Regular inspection before each flight helps identify cracks, chips or warping that indicates replacement is needed.
- Is this a single propeller or a set? — This is a set of two complete propeller and spinner assemblies (marked as "2" in the product designation), providing you with a replacement pair or allowing you to keep backups for extended flying sessions without propeller swaps between flights.
- What is the difference between this E-flite propeller and the HobbyZone branded alternative? — Both E-flite and HobbyZone produce quality propellers compatible with the Champ platform. The E-flite Prop and Spinner 130 x 70 represents the original equipment manufacturer choice, whilst HobbyZone propellers (such as the HBZ4401) are alternative options. Both are respected choices; selecting between them is largely a matter of personal preference and availability.
