Product overview
The Gemfan 5129 YUKI PC 3 Blade is a three-blade propeller for 5-inch FPV racing drones, with additional applications in freestyle flying and throttle-response training. Its PC construction combines a 129.7 mm diameter with a 2.9-inch pitch and a weight of 4.5 g per propeller. The pitch was revised in response to pilot feedback to improve its fit with racing powertrains and support finer throttle control during technical maneuvers, including operation at high throttle positions.
Integration centers on a 5 mm mounting hole, a 6.1 mm center thickness, and a maximum propeller width of 14.7 mm. Recommended motor sizes are 2306 and 2207, paired with an ideal aircraft takeoff weight of 500–600 g. These recommendations define the intended installation context for the propeller. The product is a propulsion component for an existing aircraft, with pink, yellow, clear gray, purple, and blue color options supporting visual orientation and customization.
