Product overview
The Gemfan Flash 5144 (5144-3) is a polycarbonate propeller for 5-inch class FPV racing and high-performance freestyle drones. Its three-blade architecture combines an approximate 129.31 mm (5.1 inch) diameter with a 4.4 inch pitch, and each propeller weighs approximately 4.68 g. The blade-tip and root-airfoil refinements target greater impact resistance. Its handling emphasis is on tracking through turns, stability during complex maneuvers and responsive acceleration, supporting racing and dynamic flight applications.
Integration centers on a 7 mm thick hub with a 5 mm shaft hole, an M5 mounting interface and POPO system compatibility. The specified motor-size range is 2205 to 2306, with 2306 recommended. High-speed optimization is specifically associated with 6S power systems. Each pack contains two clockwise and two counterclockwise propellers, making this a propulsion-component pack rather than a flight platform or airframe kit. Color choices comprise transparent, translucent blue, translucent red, translucent gray and fluorescent yellow.
