Gemfan 40mm 2-Blade Propellers – Lightweight and Efficient Two-Blade Propellers for Tiny Whoop FPV Drones

The Gemfan 40mm 2-Blade Propellers are premium-quality two-blade propellers designed for Tiny Whoop and other micro FPV drones, where low weight, rapid throttle response, and maximum efficiency are essential. Thanks to GemFan’s precisely optimised aerodynamic design, these propellers provide smooth handling, stable flight characteristics, and an excellent balance between thrust and flight time.

With a 40 mm diameter, these propellers are an ideal choice for lightweight 1S micro FPV drones, including Air75-class models and other compatible platforms. Their transparent finish gives your drone a clean, modern appearance while complementing a wide variety of frames and electronic components.

Two-Blade Design for Maximum Efficiency

The Gemfan 40mm 2-Blade Propellers feature a two-blade design that reduces aerodynamic drag and rotational mass compared to three-blade propellers. As a result, motors require less power to spin the propellers, improving energy efficiency and extending flight time.

The lightweight construction also allows motors to reach their target RPM more quickly, delivering precise throttle response and a smooth flying experience. These characteristics make the propellers especially popular for Tiny Whoop racing, technical indoor courses, and everyday FPV flying.

Optimised for Micro FPV Motors

The propellers are equipped with a 1.0 mm shaft hole, ensuring compatibility with a wide range of popular brushless micro FPV motors. The standard mounting system allows for quick installation and easy replacement whenever needed.

Their 40 mm diameter offers an excellent balance between thrust, flight speed, and power efficiency. This enables the drone to maintain excellent manoeuvrability while providing longer flight times without sacrificing performance.

Durable and Precisely Balanced Construction

The Gemfan 40mm 2-Blade Propellers are manufactured from high-quality, impact-resistant material that withstands everyday flying, minor crashes, and hard landings. Their lightweight construction reduces rotational mass, allowing motors to respond more quickly to throttle inputs while improving the drone’s overall agility.

Each propeller is precisely balanced to minimise vibration, resulting in improved flight stability and smoother FPV video footage. Reduced vibration also lowers the load on motors and drivetrain components, helping to extend the lifespan of your drone’s power system.

Perfect for Tiny Whoop and Air75 Platforms

Thanks to their lightweight design and excellent efficiency, the Gemfan 40mm 2-Blade Propellers are ideal for Tiny Whoop racing, freestyle flying, and everyday FPV practice. They provide fast directional changes, precise handling, and a smooth flying experience in both indoor and outdoor environments.

The package includes four transparent propellers, consisting of two clockwise (CW) and two counter-clockwise (CCW) propellers, ensuring correct installation and compatibility with most micro FPV drones. They are an excellent choice as replacement propellers or for building a new Air75 or other compatible 1S micro FPV drone.
