Description

The HQProp Duct-T90MMX3 propeller is engineered for the unique demands of 3-inch Cinewhoop drones, where protected ducts require a specific blade profile to generate efficient thrust. The 90mm diameter and 3-inch pitch are calibrated to work within the physical constraints of ducted frames, providing the lift and control necessary for precise, cinematic flying while minimizing turbulence.

Made from high-grade polycarbonate, these blades offer a critical balance of rigidity and slight flexibility. This material choice ensures consistent performance under load from high-KV motors while providing a degree of durability against minor impacts, a common occurrence in proximity flying. The tri-blade configuration delivers a favorable mix of thrust authority and prop wash handling, contributing to stable video footage.

Key Features

Duct-Optimized Aerodynamics: Blade shape and pitch are specifically designed to perform efficiently within the confined airflow of Cinewhoop ducts, maximizing thrust output.
Polycarbonate Construction: Provides excellent dimensional stability and strength, resisting deformation at high RPMs for predictable flight characteristics.
Multi-Shaft Hub Compatibility: The 11mm hub is engineered to press-fit securely onto 1.5mm, 1.9mm, and 2.0mm motor shafts without the need for adapter rings.
Balanced Performance: Each propeller is manufactured to tight tolerances, reducing the need for manual balancing and ensuring smooth motor operation.
Cinewhoop-Specific Tuning: The thrust and pitch profile prioritize smooth, controllable power over raw top speed, ideal for stabilized cinematic flight.

Applications

3-inch protected duct Cinewhoop builds for smooth cinematic FPV footage.
Indoor or tight-space FPV flying where propeller guards or ducts are mandatory.
Freestyle Cinewhoop platforms requiring a balance of agility and prop-wash handling.
Long-range 3-inch micro drones utilizing ducted frames for added efficiency and prop protection.

Frequently Asked Questions

What motor shaft sizes are these HQProp Duct-T90MMX3 propellers compatible with?

The propellers feature an 11mm press-fit hub designed to be compatible with 1.5mm, 1.9mm, and 2.0mm motor shafts. No adapter rings are required or included; the hub is engineered to securely fit these standard sizes through a friction press-fit installation.

Are these propellers suitable for high-KV motors on 3-inch Cinewhoops?

Yes, the Duct-T90MMX3 is specifically designed for the performance profile of 3-inch Cinewhoops, which often use high-KV motors (e.g., 3000KV+ on 3S or 4S). The polycarbonate construction provides the necessary rigidity to handle high RPMs without flexing, while the 3-inch pitch offers controllable thrust ideal for cinematic flying rather than raw speed.

Why is this propeller design specific to 'ducted' or 'Cinewhoop' applications?

Ducted frames significantly alter airflow around the propeller. The Duct-T90MMX3's blade geometry and 3-inch pitch are optimized to work efficiently within this confined environment, reducing turbulence and cavitation that standard propellers experience. This results in more consistent thrust, better low-speed control, and quieter operation—key factors for capturing stable FPV video.
