Product overview
The Gemfan 9150-3 uses three glass fiber nylon blades in a nominal 9-inch format, with a specified diameter of 231.14mm and a 5in pitch. Its intended applications include high-altitude racing, plateau operation, professional aerial cinematography and heavy-lift FPV drones. The black propeller combines matte and glossy surfaces, a treatment intended to improve aerodynamic efficiency and reduce stalling risk at high speeds. The configuration described is a propulsion component for integration into a drone.
Mechanical integration centers on a 5mm hub bore and an 8mm center thickness. Maximum propeller width is 29.3mm, and weight is 23.4g. Gemfan recommends a 3115 1000kv motor, providing a specific motor reference for propulsion selection. The stated aircraft application covers quads with takeoff weight up to 1.5 kg; this figure describes total aircraft takeoff weight rather than a payload allowance. The supplied product description identifies the black three-blade propeller, without specifying package quantity or additional included mounting equipment.
