Description
The Gemfan 5129.2 is a lightweight racing propeller co-developed with renowned Korean pilot Minjae, engineered for sharp, responsive handling in high-speed flight. Weighing only 4.12 g per prop—10% lighter than conventional racing propellers—its reduced rotational inertia delivers noticeably quicker steering and precise control. Made from durable PC material, it features a 130.3 mm diameter, 2.92-inch pitch, and a standard 5 mm center hub, with a center thickness of 6.2 mm and max blade width of 14.9 mm. Optimized for 2207 motors and an ideal takeoff weight of 500 g, it offers pilots greater confidence and control when every millisecond counts. Available in multiple translucent colors—Clear Grey, Clear Blue, Clear Purple, Clear Yellow, and Clear Pink—for personalization and visual tracking.
