Key Features
- 11-Blade Rotor Design — The precision 11-blade fan configuration delivers optimised thrust and efficiency across a wide flight envelope, providing the responsive acceleration and smooth power delivery that jet pilots demand for dynamic manoeuvres and sustained high-speed flight.
- 64mm Size Standard — The 64mm ducted fan format is the established platform for serious electric RC jet flying, offering proven performance and an extensive ecosystem of compatible airframes, electronics and accessories available from multiple manufacturers worldwide.
- Genuine E-flite Engineering — As an official E-flite component, this ducted fan unit is engineered to exacting standards and manufactured using quality materials and processes that ensure reliability, durability and predictable performance that aftermarket alternatives simply cannot match.
- Direct Fit Compatibility — This unit is designed as a direct replacement for E-flite 64mm EDF jet airframes including the Viper 64mm EDF Jet, eliminating guesswork and ensuring perfect fitment without modification or adaptation.
- Thrust Tube Integration — The ducted fan unit features a complete thrust tube assembly, providing the structural backbone necessary for secure engine mounting and efficient force transmission to your airframe during acceleration and high-G manoeuvres.
- Hub and Shaft Assembly — The precision-manufactured hub and shaft system ensures balanced rotor operation, minimising vibration and ensuring smooth, reliable power delivery throughout your flight envelope from hover through maximum speed.
Technical Performance
The E-flite 64mm Ducted Fan Unit represents mature engineering optimised for electric jet performance. The 11-blade rotor configuration delivers responsive thrust characteristics suitable for aerobatic flying, high-speed passes and sustained cruise flight. The 64mm diameter is the industry standard for mid-scale electric RC jets, with the Viper 64mm EDF Jet and other comparable airframes demonstrating that this platform delivers exceptional power-to-weight ratios and flight dynamics. The complete ducted fan assembly includes the rotor hub, thrust tube and all structural components necessary for immediate installation into compatible E-flite 64mm EDF airframes. The precision manufacturing ensures that airflow remains optimised within the duct, converting motor power into maximum usable thrust while minimising turbulence and noise. The rotor assembly is designed for rapid tool-free removal and installation, allowing quick maintenance, cleaning and inspection of the fan blades themselves. The thrust tube provides rigid mounting for the motor and fan assembly whilst the aerodynamic duct shape channels and accelerates airflow for maximum efficiency. For UK RC jet enthusiasts, this represents genuine factory spares support from E-flite, with the reassurance that every component meets original design specifications and quality standards. The ducted fan is a wear item in high-performance flying applications, making access to genuine replacement units essential for maintaining your aircraft's performance and reliability.

Frequently Asked Questions
- What is a 64mm EDF and why should I choose this ducted fan unit for my RC jet? — EDF stands for Electric Ducted Fan. The 64mm diameter is the established mid-scale standard for electric RC jets like the E-flite Viper, offering proven performance, widespread availability of compatible components, and sufficient thrust for dynamic flight manoeuvres. Choosing a genuine E-flite unit ensures perfect compatibility and reliable performance.
- Will this 11-blade rotor fit my E-flite Viper 64mm EDF Jet? — Yes, this ducted fan unit is specifically designed as a direct replacement component for E-flite 64mm EDF jet airframes including the Viper. The unit incorporates the complete assembly including rotor, hub and thrust tube, providing everything needed for a straightforward installation into your airframe.
- How often should I replace my ducted fan unit? — The rotor blades are subject to wear and potential damage from dust ingestion, bearing wear and impact during operations. Regular inspection during maintenance is recommended. Many pilots keep spare rotors and complete fan assemblies on hand for rapid replacement and to minimise downtime during flying season.
- What motor size works with the 64mm EDF? — The 64mm platform accommodates various brushless outrunner motors sized appropriately for the duct diameter. Specific motor recommendations depend on your airframe specifications and desired performance characteristics. Consult the manual for your E-flite 64mm EDF jet airframe to identify compatible motor specifications.
- Can I upgrade my existing 64mm EDF jet with this rotor? — This is a direct component replacement for E-flite 64mm EDF jets. If your airframe currently uses a 64mm ducted fan, this genuine E-flite rotor will provide excellent performance. However, ensure your motor, ESC and battery system are rated for the thrust output of a quality 11-blade rotor at full power.
- Is the 64mm EDF suitable for beginners to RC jet flying? — The 64mm EDF platform represents an excellent entry point into RC jet flying, offering more predictable and docile flight characteristics than larger jets whilst still delivering genuine aerobatic capability and exciting performance. However, electric RC jets generally require more setup knowledge than beginner-oriented foam RC aircraft, and we recommend consultation with experienced RC pilots before your first flight.
