Product overview
The Gemfan Flash 5149 is a propulsion component for FPV racing and freestyle drones. Its three-blade architecture uses polycarbonate (PC), with a diameter of 5.1 inch (~129.5 mm), a pitch of 3.5 inch and an approximate weight of 4.59 g per propeller. The design targets responsive thrust and predictable aircraft control during racing and freestyle maneuvers. Its material construction is intended to combine low weight with durability and impact resistance for these dynamic flight applications.
Integration centers on a 5 mm shaft hole (M5), with compatible motor sizes specified as 2205 to 2306. Intended applications include 5-inch class platforms seeking a balance between power and control; the actual propeller diameter remains 5.1 inch. Each pack supplies two clockwise and two counterclockwise propellers. The supplied configuration is a propeller pack, and its stated integration scope is defined by the mounting interface, motor-size range and intended platform class.
