BetaFPV GemFan 45mm 3-Blade Propellers 1.5mm Shaft (4pcs) Blue

Precise Control and Maximum Performance for Micro FPV Drones

BetaFPV GemFan 45mm 3-Blade Propellers are designed for pilots who want to get the most out of their micro and whoop-class FPV drones in terms of performance, stability, and flight precision. Thanks to their carefully optimised aerodynamic profile, these propellers deliver an excellent balance of thrust, responsiveness, and energy efficiency, making them ideal for FPV racing, freestyle flying, and everyday recreational use.

GemFan is well known in the FPV community for producing high-quality, durable propellers, and the BetaFPV GemFan 45mm continues that tradition. The three-blade design generates greater airflow and thrust than conventional two-blade propellers, providing faster acceleration, more precise throttle control, and improved flight stability even during demanding manoeuvres.

Optimised 45 mm Size for Modern Whoop Drones

The 45 mm diameter makes these propellers an excellent choice for many popular micro FPV platforms, including the BetaFPV Meteor75 Pro and other drones of a similar size. They feature a 1.5 mm shaft mounting hole, ensuring a secure connection between the motor and the propeller while helping to minimise vibration at high RPM.

Their aerodynamic blade profile moves air efficiently while maintaining a smooth flight feel and rapid response to pilot inputs. This results in more precise control and greater confidence whether flying through tight indoor spaces or in open outdoor environments.

Durable Construction for Everyday Flying

The propellers are manufactured from high-quality polycarbonate (PC), combining flexibility with excellent durability. This allows them to better withstand minor crashes, hard landings, and the everyday wear that is inevitable in FPV flying. The material’s flexibility helps reduce the risk of breakage while extending the service life of the propellers compared to more rigid alternatives.

The blue finish gives your drone a distinctive appearance while also making it easier to track during fast manoeuvres.
