HQProp Duct-4x4x6 4" 6-Blade Ducted Fan Propeller (M5 Mount) for FPV Drone
Or FAST delivery Sun, Jul 26
HQProp Duct-4x4x6 is a purpose-built 4-inch, 6-blade ducted fan propeller designed for FPV drones. With an M5 mounting option, it integrates cleanly into compact, high-precision rigs where ducted propulsion matters as much as raw thrust.
The ducted design channels air for cleaner, more predictable thrust in tight builds, while the 6-blade configuration adds load-bearing surface to deliver responsive throttle and stable hover without sacrificing agility. This propeller is optimized for FPV applications where protection, efficiency, and controlled performance are essential.
Key features
- Diameter and length: 4 inches, compact for small frame quads
- Blades: 6-blade configuration for improved thrust response
- Ducted design: protects blades and helps manage airflow in enclosed spaces
- Mount: M5 mounting compatible with common ducted-fan motors
- Application: ideal for FPV drones requiring compact, efficient ducted propulsion
Recommended use: pair with the appropriate motor and flight controller settings for predictable throttle curves, crisp climbs, and smooth dives. Regular inspection of duct alignment and blade tips will help maintain peak performance and safety during rapid maneuvers.
