BetaFPV Gemfan 2020 4-Blade Propellers – High-Performance Four-Blade Propellers for Micro FPV Drones

The BetaFPV Gemfan 2020 4-Blade Propellers are premium-quality four-blade propellers designed for FPV pilots who demand maximum thrust, precise handling, and stable flight performance. GemFan’s aerodynamic design, combined with durable polycarbonate construction, provides an excellent balance of power, efficiency, and reliability, making these propellers an ideal choice for freestyle flying, racing, and technical flight manoeuvres.

With a 50.3 mm propeller diameter, these propellers are perfectly suited for modern micro FPV drones where rapid throttle response and stable control are essential. Their transparent black finish gives your drone a sleek, professional appearance while complementing a wide variety of frames and electronic components.

Four-Blade Design for Maximum Control

The BetaFPV Gemfan 2020 4-Blade Propellers feature an aerodynamic four-blade design that increases airflow and produces more thrust than traditional two- or three-blade propellers. The additional blades provide faster throttle response, improved grip in the air, and greater control during demanding flight manoeuvres.

This design is particularly well suited for freestyle flying, navigating tight spaces, and technical racing courses where stability and precise control are critical. The four-blade configuration also delivers smoother flight characteristics while maintaining excellent control during rapid acceleration and aggressive braking.

Optimised for 1103–1105 Series Brushless Motors

The BetaFPV Gemfan 2020 4-Blade Propellers feature a 1.5 mm shaft hole, ensuring broad compatibility with many popular micro FPV brushless motors. They are specifically recommended for use with the 1103 8000KV motor as well as other 1103–1105 series brushless motors to achieve optimal performance.

Their 50.3 mm propeller diameter, 4.5 mm hub thickness, and precisely engineered blade profile provide a secure fit on the motor shaft while ensuring efficient power transfer even at high RPM. This combination allows the drone to achieve an excellent balance between thrust, handling, and power efficiency.

Durable and Lightweight Polycarbonate Construction

The BetaFPV Gemfan 2020 4-Blade Propellers are manufactured from high-quality polycarbonate (PC), combining low weight with exceptional impact resistance. Each propeller weighs just 0.93 grams, reducing rotational mass and allowing the motors to respond more quickly to throttle inputs.

Their precisely balanced construction helps minimise vibration, resulting in improved flight stability and smoother FPV video footage. Reduced vibration also decreases stress on the motors and drivetrain components, helping to extend the lifespan of your drone’s entire power system.

Perfect for Freestyle and Racing Drones

Thanks to their high thrust and precise handling, the BetaFPV Gemfan 2020 4-Blade Propellers are an excellent choice for micro freestyle drones, cinewhoops, and racing drones. They deliver rapid acceleration, stable flight characteristics, and confident control in both indoor and outdoor flying environments.

The package includes four transparent black propellers, consisting of two clockwise (CW) and two counter-clockwise (CCW) propellers. This complete set allows for immediate installation and makes an excellent choice as replacement propellers or for building or upgrading a micro FPV drone.
