Gemfan 8040-3 High-Altitude 3-Blade Propeller for Cinelifter and Macro Quad Builds - 8.0-Inch PC
The Gemfan 8040-3 is an 8.0-inch, 3-blade propeller with a 4.0-inch pitch, built for cinelifters, macro quads and heavy-lift drones. It is made from either Polycarbonate (PC) giving a good balance of strength, impact resistance and low weight at 10.5 g per propeller. The 5 mm (M5) shaft hole fits motors in the 2808 to 3118 range.
The blade design is tuned for stable, efficient thrust in demanding conditions such as high altitude and cold, low-density air. It is well-suited to X8 (coaxial) configurations, where the extra thrust and redundancy help with professional aerial filming, industrial inspection and payload delivery. Each pack contains 1 CW and 1 CCW propeller.
