Lightweight 5.1-Inch 3-Blade Racing Propeller with 2.92-Inch Pitch for Fast FPV Response
The Gemfan MinJae 5129.2 is a lightweight 3-blade FPV racing propeller co-developed with Korean FPV pilot Minjae for fast steering response and precise control during high-speed flight. With a diameter of 130.3 mm, equivalent to approximately 5.1 inches, and a 2.92-inch pitch, the propeller is designed for racing and agile freestyle builds where rapid throttle changes and quick directional corrections are important. Each propeller weighs approximately 4.12 g, reducing rotational inertia for faster motor response.
Manufactured from durable PC material, the MinJae 5129.2 combines low weight with impact-resistant construction for repeated FPV use. It features a standard 5 mm centre mounting hole, 6.2 mm centre thickness and 14.9 mm maximum blade width, making it well-suited for compatible 2207 motors and approximately 500 g take-off-weight racing builds. CW and CCW rotation options support quadcopter installation, while translucent Clear Grey, Clear Blue, Clear Purple, Clear Yellow and Clear Pink colour variants provide visual customisation.
