Overview
The E-flite Propeller 160 x 35mm is the genuine OEM spare part designed specifically for the UMX Eratix 450mm micro aerobatic RC model. Whether you're a seasoned RC enthusiast flying competitive 3D aerobatic manoeuvres or a hobbyist enjoying weekend flying sessions, having the correct replacement propeller on hand is essential for maintaining peak performance. This is the official E-flite part that ensures your UMX Eratix 450mm continues to deliver the balanced, efficient thrust that this precision aircraft demands.
Micro aerobatic models like the UMX Eratix 450mm require precision engineering in every component, and the propeller is no exception. When your original prop becomes worn, damaged, or sustains the inevitable nicks and cracks that come from active flying, performance suffers. Vibration increases, thrust becomes unbalanced, and your flying experience deteriorates. The EFL-3144 propeller restores your model to factory specifications, ensuring smooth operation and reliable performance every time you take to the skies. This makes it an invaluable field spare for RC pilots across the UK who demand consistency and reliability from their equipment.
As a genuine E-flite component, this propeller is engineered to match the original specifications exactly. It measures 160mm in diameter with a 35mm pitch, making it the perfect like-for-like replacement when your existing prop needs retirement. Stocking this spare means minimal downtime between flights and maximum enjoyment of your investment in quality RC aircraft.
Key Features
- Genuine E-flite OEM Part — This is the authentic factory propeller designed by the manufacturers of the UMX Eratix 450mm, ensuring perfect compatibility and guaranteed performance that matches your aircraft's original specifications.
- Optimised 160 x 35mm Specification — The 160mm diameter combined with 35mm pitch has been engineered specifically for the UMX Eratix 450mm to deliver balanced thrust distribution and smooth, vibration-free operation during 3D aerobatic flight.
- Quick Field Replacement — Designed as a convenient spare for pilots who fly regularly, this propeller allows you to swap out a damaged prop in minutes and get back in the air without lengthy repairs or waiting for replacements to arrive.
- Maintains Efficient Thrust — Using the correct OEM propeller helps maintain the aerodynamic efficiency your aircraft was designed for, preventing the performance degradation and increased vibration that occurs with worn or incompatible props.
- Reduces Vibration — Micro aerobatic models are sensitive to imbalance, and a correctly specified propeller significantly reduces vibration during flight, improving control response and protecting your aircraft's bearings and airframe from unnecessary stress.
- Cost-Effective Spares Solution — Rather than replacing your entire aircraft when the propeller fails, this affordable spare part keeps your UMX Eratix 450mm flying season after season.
Technical Performance
The EFL-3144 propeller measures 160 x 35mm and is manufactured to the exacting standards that E-flite applies to all OEM components for the UMX range. The 160mm diameter provides the optimal aerodynamic profile for the UMX Eratix 450mm's airframe and flight envelope, whilst the 35mm pitch is calibrated to deliver smooth, controllable thrust suitable for both precision aerobatic manoeuvres and stable cruising flight. Micro aerobatic aircraft like the UMX Eratix 450mm operate in a highly engineered environment where every component must work in harmony—the propeller is no exception. This genuine E-flite propeller has been tested to ensure it maintains the balanced weight distribution and aerodynamic efficiency required for stable flight. The propeller's design minimises vibration that would otherwise compromise control response and structural integrity. For UK-based RC pilots flying micro aerobatic models competitively or recreationally, using the correct OEM propeller is not simply a recommendation—it is essential for realising the full potential of your aircraft and ensuring reliable performance throughout your flying season. The propeller is an ideal field spare for quick repairs, allowing you to maintain continuous flying without extended downtime.

Frequently Asked Questions
- Is this propeller compatible with other RC models besides the UMX Eratix 450mm? — This propeller is specifically designed as a replacement for the UMX Eratix 450mm. Whilst the 160 x 35mm specification may fit other aircraft, E-flite recommends using model-specific propellers to ensure optimal performance and safety. Always verify compatibility with your model's documentation before installation.
- How often will I need to replace the propeller on my UMX Eratix 450mm? — The frequency of propeller replacement depends on your flying intensity and environmental conditions. Active fliers should inspect their propeller regularly for cracks, nicks, and damage after each flight. Many UK RC enthusiasts keep 2-3 spare propellers on hand to minimise downtime. If your propeller has visible damage or makes unusual noises during flight, replacement is recommended immediately.
- What's the difference between this genuine E-flite propeller and generic alternatives? — The EFL-3144 is manufactured to exact OEM specifications by E-flite using controlled tolerances and materials selected to match your aircraft's design requirements. Generic propellers may have different weight distribution, aerodynamic profiles, or material properties that can introduce vibration, reduce efficiency, and potentially compromise flight safety. For precision aircraft like the UMX Eratix 450mm, genuine parts are the best choice.
- Can I use this as a field spare to keep flying between sessions? — Yes, absolutely. This propeller is specifically recommended as a handy field spare for quick repairs and minimal downtime. Many UK pilots keep one in their flying kit for emergencies. If your propeller sustains damage during a flight, simply swap it out and continue flying whilst you repair or replace the damaged prop at home.
- Why is using the correct propeller important for my UMX Eratix 450mm? — Micro aerobatic models are precisely engineered aircraft where every component contributes to balanced, efficient performance. The correct propeller maintains the thrust characteristics your airframe was designed for, prevents vibration that can stress bearings and joints, and ensures predictable control response during 3D manoeuvres. Using an incorrect or damaged propeller significantly degrades flight quality.
- How do I know if my propeller needs replacement? — Inspect your propeller before each flying session. Look for cracks, bends, splintering, or visible damage to the blade surfaces. During flight, listen for unusual buzzing or vibration that wasn't present before. If you notice performance degradation, increased vibration, or any visible damage, replacement is recommended. Damaged propellers can fail suddenly during flight, so don't ignore warning signs.
