Product details
Gemfan Flash 5152S Tri-Blade Propeller
Blade Count: 3
Diameter: ~127 mm (5.1 inch)
Pitch: 5.2 inch
Weight: ~5 g (per propeller)
Material: PC (Polycarbonate)
Hub Thickness: 8 mm
Mounting Interface: 5 mm shaft hole (M5)
Compatible Motor Size: 2205 to 2306
Packaging: 2 CW + 2 CCW per pack
Engineered for high-speed racing environments, the Gemfan Flash 5152S focuses on optimized aerodynamic efficiency and responsive performance. It utilizes a thin, lightweight structure combined with a downward-deflected blade tip design to reduce induced drag and rotational inertia, thereby enhancing throttle response and flight speed. Developed through a systematic engineering process involving 3D modeling and fluid dynamics simulation, this tri-blade propeller iteratively refines airfoil curvature, thickness distribution, and surface airflow to achieve a coordinated balance between lift-drag characteristics and motor output. Overall, the Flash series is tailored for racing with targeted aerodynamic and structural optimizations, seeking harmony between efficiency, responsiveness, and flight stability for pilots with high demands for speed performance.
