Product overview
The Gemfan GEMFAN1309-3 glass fiber nylon prop is an electric propeller for 13-inch-class heavy-lift aerial platforms. Its three-blade architecture combines a 13 inch diameter with a 9 inch pitch and fiberglass-reinforced nylon construction. The blade structure is shaped around motor mounting configurations, with reduced weight and rotational inertia as design objectives. Intended applications include heavy-lift drones requiring balanced thrust and dynamic response, professional aerial photography and industrial inspection platforms, and long-endurance flight systems prioritizing efficiency and control.
The mounting interface is a 6 mm / 0.236 inch shaft bore. Recommended pairings use 4115 motors at approximately 600 KV, with the propeller intended for platforms at approximately 8.3 kg takeoff weight. That weight describes the aircraft configuration rather than a payload capacity. Each pack supplies two black propellers: one clockwise and one counterclockwise unit. This paired configuration supports installation in dual-motor and multirotor arrangements, while the bore dimension defines the physical mounting interface for compatible motors.
