Description

The Pro-Range D75 ducted propellers are engineered for 3-inch drone platforms requiring efficient, protected propulsion. The polycarbonate construction provides the necessary rigidity to maintain pitch accuracy at high RPMs while resisting deformation, ensuring consistent thrust delivery throughout the flight envelope. The 3.4-inch pitch is optimized to generate ample lift without overloading smaller 1105-1303 class brushless motors commonly used in ducted configurations.

These props are specifically designed for ducted frames, where the blade tips operate within a protective shroud. This design minimizes prop wash interference and enhances safety for indoor or proximity flying. The inclusion of both 1.5mm and M5 mounting holes ensures broad compatibility with a wide range of micro motor shafts, simplifying the build process for pilots.

Key Features

Ducted Propeller Design: Optimized for 75mm (3-inch) ducted frames, reducing tip turbulence and enhancing safety for indoor and proximity flight.
Polycarbonate (PC) Material: Offers high impact resistance and dimensional stability, maintaining precise blade geometry under load for predictable flight characteristics.
Dual Mounting Hole Pattern: Features both 1.5mm and M5 center holes, providing direct compatibility with a wide range of micro brushless motor shafts without adapters.
Balanced 3-Blade Aerodynamics: The three-blade configuration and 3.4-inch pitch provide a favorable balance of thrust, efficiency, and acoustic performance for freestyle and cinematic flying.
Precision-Molded Construction: Ensures excellent hub balance and consistent blade weight, reducing vibration for smoother video footage and longer motor bearing life.

Applications

3-inch CineWhoop builds for smooth, protected indoor and outdoor cinematic footage.
Compact FPV freestyle drones utilizing 75mm ducted frames for agile, proximity flying.
Micro long-range builds based on lightweight 3-inch ducted platforms.
Tiny Trainer and beginner-friendly drones where propeller guards are essential for safety.
Lightweight payload carriers requiring efficient, shrouded propulsion on a small scale.

Frequently Asked Questions

What motor shaft sizes are these D75 propellers compatible with?

These propellers feature a dual mounting hole pattern, making them directly compatible with motors using either a 1.5mm threaded shaft or an M5 threaded shaft. This covers a wide range of popular 1105, 1106, 1204, and 1303 brushless motors commonly used in 3-inch ducted builds without the need for adapters.

Are these props suitable for high-RPM 4S or 6S setups on a 3-inch drone?

While the polycarbonate construction is durable, the 75mm size and 3.4-inch pitch are primarily optimized for 3S and 4S power systems on lightweight builds. For aggressive 6S setups, ensure your motor KV is appropriately low (e.g., under 3000KV) to avoid overloading the motors and exceeding the propeller's recommended RPM limits, which could lead to flex or imbalance.

Do I need to balance these Pro-Range D75 propellers before use?

Precision molding generally provides good hub balance straight from the package. However, for the smoothest flight performance and highest quality video footage, especially in cinematic applications, it is always recommended to perform a dynamic balance check. Minor balancing with tape or light sanding can further reduce high-frequency vibrations.
