Description

The Pro-Range D2.5 Ducted Propeller utilizes a precision-molded polycarbonate airfoil to achieve an optimal balance between structural rigidity and minimal mass. This 3-blade configuration is specifically tuned for the constrained airflow within ducted cinewhoop frames, generating consistent thrust with enhanced low-speed stability and control authority.

Engineered with enhanced dynamic balancing from the factory, these propellers significantly reduce high-frequency vibrations that can interfere with sensitive flight controllers and digital HD video feeds, such as the DJI O4 system. The 1.5mm T-mount interface ensures a secure, non-slip connection to compatible micro brushless motors, maintaining precise alignment throughout aggressive flight maneuvers.

Key Features

Ducted 3-Blade Airfoil: Optimized profile for efficient thrust generation within protective ducts, reducing prop wash and turbulence.
Polycarbonate Durability: High-impact PC material resorts to cracking and deformation under stress, offering a high strength-to-weight ratio.
Precision Dynamic Balance: Factory-balanced blades minimize harmonic vibrations for smoother flight and cleaner video footage.
DJI O4 HD Compatibility: Low-vibration design helps eliminate jello and interference in high-definition digital FPV systems.
Secure T-Mount Interface: 1.5mm center hole with T-slot provides positive locking against motor shafts to prevent slippage.
Lightweight Construction: At 1.2g per propeller, it minimizes rotational mass for quicker motor response and longer flight times.

Applications

2.5-inch ducted cinewhoop builds for indoor/outdoor cinematic FPV filming.
Sub-250g (Tiny Whoop) drones utilizing 1404 or similar sized micro brushless motors.
HD digital FPV platforms (DJI O4, Walksnail Avatar) requiring low-vibration propellers for jello-free video.
Lightweight freestyle and proximity flying where duct protection is essential.

Frequently Asked Questions

What motor size and KV are these D2.5 propellers designed for?

These propellers are optimized for 1404-size brushless motors with a KV rating around 4600. This combination is standard for 2.5-inch ducted cinewhoops running on 3S or 4S LiPo batteries, providing the ideal torque and RPM for efficient thrust and responsive control within the sub-250g weight class.

Are these propellers compatible with DJI O4 HD FPV systems?

Yes. The propellers are factory dynamically balanced to minimize vibration, which is critical for preventing 'jello' effect and RF interference in high-definition digital video systems like DJI O4. Their low-vibration design helps ensure clean, stable video transmission from your air unit.

What is the difference between a standard mount and the 1.5mm T-mount on these props?

A 1.5mm T-mount features a small horizontal slot (the 'T') in the center hole that mates with a corresponding tab on the motor shaft. This provides a positive locking mechanism, preventing the propeller from slipping or rotating independently on the shaft during rapid throttle changes, which is crucial for maintaining timing and control in ducted whoop applications.
