Gemfan 90mm 3.5" 5-Blade Ducted Cinewhoop Propeller High-Efficiency Low-Noise Cinematic Props (Set of 4)

Capture ultra-smooth, cinematic aerial footage seamlessly with the premium Gemfan D90 90mm 3.5″ 5-Blade Ducted Cinewhoop Propeller (Set of 4). Specifically engineered to thrive within tight protective ducts, this high-efficiency propeller layout maximizes air intake velocity while minimizing tip vortex turbulences. Whether you are navigating tight indoor real estate layouts on commercial shoots or chasing outdoor athletes over obstacles, the Gemfan D90 90mm 3.5″ 5-Blade Ducted Cinewhoop Propeller (Set of 4) delivers the lifting capacity required to steady heavy action cameras and high-definition digital video transmitters without sacrificing flight dynamics.

Acoustic dampening meets robust structural balance. The intentional 5-blade distribution of the Gemfan D90 90mm 3.5″ 5-Blade Ducted Cinewhoop Propeller (Set of 4) shifts the aircraft's sound frequency upwards, dampening standard low-frequency multi-rotor noise into a quiet hiss. This makes the Gemfan D90 90mm 3.5″ 5-Blade Ducted Cinewhoop Propeller (Set of 4) perfect for capturing audio on film sets or flying near people without causing a distraction. Forged from high-grade polycarbonate, these propellers hold their aerodynamic curvature under heavy throttle loads, completely neutralizing structural flex and eliminating unsightly video "jello" artifacts right off the workbench. 

Key Technical Features

• Propeller Diameter: 90mm (3.5-inch) sizing perfectly tailored for modern high-performance cinewhoop ducts.
• Blade Geometry: Specialized 5-blade configuration delivering maximum low-end thrust and stability for heavy camera payloads.
• Pitch Profile: 2.4-inch pitch optimized for smooth linear throttle tracking, precise altitude control, and rapid cornering recovery.
• Hub Configuration: Standard 5mm center mount paired with integrated 1.5mm/2mm t-mount adapter holes for universal motor compatibility.
• Material Integrity: Forged from high-impact polycarbonate plastic ensuring structural rigidity and durability against duct scraping.
• Package Quantities: Ships as a complete matching set of 4 propellers (2 Clockwise - CW, 2 Counter-Clockwise - CCW).

The 5-blade configuration dramatically increases the aggregate surface area of the propeller array, allowing the drone to generate substantial thrust at lower motor RPMs. Within a ducted profile, this denser blade placement builds up high-pressure columns efficiently, reducing prop-wash oscillations during descending maneuvers and providing a locked-in, stable hover. This translates directly into highly linear throttle control and predictable handling curves when executing smooth panning shots with heavy cinema rigs.

The 90mm outer radius is precision-cut to maintain an ultra-tight tip clearance when installed inside standard 3.5-inch cinewhoop ducts, optimizing thrust efficiency by keeping air from slipping over the blade edges. Because of the high rotational resistance of 5 distinct blades, these propellers pair best with high-torque brushless motors ranging from 2004 to 2203.5 sizes. Ensuring proper motor pairings prevents excessive electrical current draws, protects your electronic speed controllers from overloading, and keeps your entire power management grid running cool.
