GEMFAN D51 2020 DUCTED PC 4 BLADE 1.5mm – 8PCS

Gemfan D51 4-Blade Ducted Cinewhoop Propeller

The Gemfan D51 (2020-4) is specifically developed to meet the demands of 2-inch ducted cinewhoop platforms. Featuring a quad-blade layout and a 2-inch pitch, it maximizes static thrust and blade surface area within duct tunnels, resulting in smoother low-end handling, reduced acoustic noise, and rock-solid stability when capturing professional close-proximity video.

Key Features

• Duct-Optimized Aerodynamics: Designed to interact efficiently with ducted frames, providing superior thrust and vertical authority.
• 4-Blade Stability: Quad-blade configuration increases air bite for smoother cinematic cruising and precise control through tight gaps.
• Low-Noise Profile: Engineered to minimize acoustic signature, making it ideal for discreet indoor and urban filming.
• Durable Polycarbonate: Built to withstand minor bumps against duct walls while maintaining structural balance.
• Secure Hub Mount: Precision-molded 1.5 mm center hole ensures a tight, reliable fit on standard cinewhoop motors.
