Description

The Pro-Range D51 2020 ducted propellers are engineered for the specific aerodynamic demands of 51mm-class micro drones and CineWhoops. The 4-blade configuration and 2-inch pitch work in tandem to generate substantial thrust at lower RPMs, improving flight efficiency and providing smoother control in confined environments typical of indoor or proximity flying.

Manufactured from high-grade Polycarbonate, these blades offer a critical balance between rigidity and impact resistance. This material choice ensures the propellers maintain their precise shape under load for consistent performance, while also being able to withstand minor collisions without catastrophic failure, a common requirement for ducted-frame applications.

Key Features

Ducted Propeller Design: Specifically shaped for optimal airflow within protective ducts, maximizing thrust efficiency for CineWhoop and micro FPV frames.
Polycarbonate Construction: High-grade PC material delivers excellent durability and impact resistance while maintaining a low weight for responsive flight characteristics.
Optimized 4-Blade Geometry: The multi-blade design increases disc area loading, providing greater low-speed thrust and improved stability compared to 2 or 3-blade counterparts.
Precision 1.5mm Mounting: Features a 1.5mm center hole with a 3-hole bolt pattern for a secure and vibration-free connection to compatible 1.5mm-shaft brushless motors.
Whisky Color Finish: Distinctive translucent amber color provides both a unique aesthetic and easy visual identification of rotation direction during pre-flight checks.

Applications

51mm (2-inch) CineWhoop drones for indoor filming and smooth, stabilized flight.
Micro FPV racing drones built on 2-inch ducted frames requiring precise throttle control.
TinyWhoop and brushless micro drone upgrades seeking enhanced thrust and durability.
Lightweight freestyle micro drones where ducted propellers offer crash protection.

Frequently Asked Questions

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

The Pro-Range D51 2020 propellers are specifically designed for 51mm (2-inch) class drone frames, most commonly used in CineWhoop and micro FPV builds. Their ducted blade shape is optimized to work efficiently within the protective ducts of these compact frames.

What motors are compatible with the 1.5mm center hole on these propellers?

These propellers are compatible with brushless motors featuring a 1.5mm motor shaft diameter. They utilize a 3-hole bolt pattern for secure mounting. Always ensure your motor's bolt pattern matches and use appropriate M1.4 or M1.6 nuts for a tight, vibration-free fit.

How does the 4-blade design affect flight performance compared to 2-blade props?

The 4-blade design increases the total disc area, generating more thrust at lower RPMs. This results in smoother, more stable flight with better low-speed control, which is ideal for precise filming and indoor flying. The trade-off is typically a slight increase in current draw and acoustic noise.
