Product overview
The Gemfan 8040-3 is a propulsion component for cinematic and heavy-lift drones, including professional aerial filming, industrial inspection and payload delivery platforms. Its physical architecture combines three blades, an 8.0 inch (~203.2 mm) diameter and a 4.0 inch pitch, with each propeller weighing 10.5 g. The airfoil and pitch are tuned for low-density air at high altitude, while the intended operating environments also include cold conditions. It supports X8 coaxial drone configurations.
Integration centers on a 5 mm shaft hole (M5) and the specified 2808 to 3118 motor range. Each pack contains one clockwise and one counterclockwise propeller, making the supplied configuration a propeller pair. Material choices are PC (Polycarbonate) and Glass Fiber Nylon: PC serves general use, while Glass Fiber Nylon offers greater stiffness, vibration damping and durability for demanding applications. The component is intended to provide stable power delivery for filming and heavy-lift work.
