16pcs HQProp Ethix S5 5x4x3 Smooth FPV Tri-Blade Propellers RC Drone Quad 5mm Shaft

HQProp Ethix S5 5x4x3 Smooth FPV Tri-Blade Propellers – 16‑Piece Set

The HQProp Ethix S5 propellers are engineered for use with remote‑controlled quadcopter drones that require a 5 mm shaft. Each propeller in the set measures 5 inches in diameter, 4 inches in height, and 3 inches in depth. The design incorporates a smooth blade surface to provide consistent airflow.

Key Features of the S5 Series

• Tri‑Blade Configuration – Three blades per propeller offer a balanced geometry for quadcopter flight.
• 5 mm Shaft Compatibility – Designed for drones equipped with a 5 mm motor shaft.
• 5×4×3 Dimension Profile – Each propeller measures 5 inches in diameter, 4 inches in height, and 3 inches in depth.
• Smooth Blade Finish – A streamlined surface that promotes efficient airflow.
• FPV Friendly – Suitable for first‑person view drone systems that require precise motor performance.
• Quadcopter Focus – Optimized for four‑motor drone setups.

Package Contents

The 16‑piece set contains four complete propeller pairs (two left‑hand and two right‑hand). Each pair is matched by side and rotation direction to ensure correct installation on a quadcopter.

Application and Compatibility

These propellers are intended for use with RC drones that use a 5 mm shaft motor. Their tri‑blade construction is suitable for quadcopter configurations and can be mounted on drone frames that support the specified shaft diameter.

Installation Guidance

When mounting, align each propeller with the correct motor shaft and secure it in place. Ensure that left‑hand and right‑hand propellers are paired appropriately to maintain balance during flight. Because the set includes multiple propellers, it is possible to replace worn or damaged blades without replacing an entire set.

Design Considerations

The S5 series is part of the HQProp Ethix line, which emphasizes smooth aerodynamic surfaces for consistent airflow. The tri‑blade design offers a middle ground between single‑blade and quad‑blade options, providing a stable thrust profile for quadcopter drones. The 5 mm shaft compatibility aligns with many modern RC drone motors, allowing for straightforward installation.

Maintenance Tips

After each flight session, inspect the propellers for signs of wear or damage. Clean debris from the smooth blade surface to preserve airflow efficiency. Store the propellers in a dry environment to prevent corrosion or warping.

Conclusion

With 16 pieces available, the HQProp Ethix S5 set offers ample options for maintenance, replacement, or experimentation with different propeller configurations on a 5 mm shaft quadcopter. The smooth, tri‑blade design is tailored to FPV drone use, ensuring that each propeller is ready for integration into a compatible RC drone system.
