Product Details
Gemfan D51 Blue Cinewhoop Props – High-Stability 4-Blade Ducted Propellers
Capture ultra-smooth, cinematic footage with the Gemfan D51 (2020) Ducted Propellers. Specifically engineered for 2-inch Cinewhoops and sub-250g micro drones, these 4-blade propellers are designed to provide maximum "grip" in the air. The high blade count offers the superior thrust and stability required for carrying heavy micro-HD cameras through tight indoor spaces or complex outdoor obstacles.
Molded from premium Polycarbonate (PC), the D51 series is built to be both lightweight and resilient. The 2-inch pitch is optimized for smooth, linear throttle management, giving you the precision control needed for professional-grade aerial videography.
Key Highlights:
Cinewhoop Optimized: The 50.3mm diameter is a perfect fit for standard 2-inch ducts, minimizing "tip loss" and maximizing ducted fan efficiency.
4-Blade Power: The quad-blade configuration provides a high lift-to-surface-area ratio, offering a smoother and quieter flight profile compared to tri-blade props.
Micro-Motor Precision: Features a 1.5mm center mount with a 3-hole pattern, making them the ideal choice for high-performance 1103 to 1105 series brushless motors.
Rugged PC Material: High-tensile polycarbonate ensures the blades can withstand high-RPM stress and minor impacts without deforming or snapping.
Ultralight Agility: At only 0.91g per prop, these blades keep your rotational mass low, allowing for faster motor corrections and a more responsive "locked-in" feel.

Pro-Pilot Tip:
The D51 4-blade design is specifically tailored for "push out" power. If you are building a 75mm or 85mm Cinewhoop, these props help eliminate the "wash-out" effect during sharp turns, keeping your horizon steady for the camera!
