Description

The Pro-Range D51 2020 ducted propellers are engineered for micro FPV drones operating within protective ducts, such as 2-inch CineWhoops. The five-blade configuration generates substantial thrust and smooth airflow, enhancing low-speed stability and control precision for indoor or proximity flying. The 1.9-inch pitch is tuned to provide a balance of quick acceleration and efficient cruise performance.

Made from injection-molded Polycarbonate, these blades offer excellent impact resistance and durability against minor collisions, a common occurrence in ducted flight. The precise molding ensures consistent weight and balance across the set, reducing vibrations for cleaner video footage and reliable motor operation.

Key Features

Five-Blade Ducted Design: Optimized for maximum thrust within the confined space of a drone duct, improving control authority.
Polycarbonate Construction: Delivers high rigidity and impact strength for a durable, long-lasting propeller.
Precision 1.9-Inch Pitch: Engineered for a responsive throttle feel and efficient power conversion from motor RPM to thrust.
Balanced Manufacturing: Each propeller is manufactured to tight tolerances for minimal vibration straight out of the package.
1.5mm 3-Hole Mounting: Standard mounting pattern ensures secure attachment to a wide range of micro brushless motor shafts.

Applications

2-inch (51mm) CineWhoop drones for cinematic indoor and proximity FPV flying.
Micro ducted FPV freestyle and racing quads requiring durable, high-thrust propellers.
TinyWhoop-style builds using 1103 to 1204 brushless motors with 1.5mm shafts.
FPV drone builds where propeller guards or ducts are integral to the frame design.

Frequently Asked Questions

What size drone frame are these D51 2020 propellers designed for?

The D51 2020 propellers are designed for 51mm ducted frames, commonly used in 2-inch CineWhoop and micro FPV drones. The '51' in the model number refers to the propeller disk diameter in millimeters, making them ideal for builds where the propellers are fully enclosed within a protective duct.

Are these propellers compatible with my micro brushless motors?

Yes, these propellers feature a standard 1.5mm 3-hole mounting pattern, which is common on many micro brushless motors in the 1103 to 1204 size range. Always verify your motor's shaft diameter and hole pattern before installation to ensure a secure fit.

What is the advantage of a 5-blade design for ducted drones?

A 5-blade design increases the total blade area within the same diameter, generating more thrust at lower RPMs compared to 3-blade props. This is particularly beneficial for ducted drones, as it improves low-speed stability, control responsiveness, and torque, which helps counteract the aerodynamic drag introduced by the duct.
