BetaFPV GemFan 1614 3-Blade Propellers 1.0mm Shaft (4pcs) Clear – Maximum Performance for Air75 II Micro FPV Drones

BetaFPV GemFan 1614 3-Blade Propellers are specifically developed for modern micro FPV drones, delivering an ideal balance of thrust, flight stability, and energy efficiency. These premium 40 mm propellers are the factory-recommended choice for the BetaFPV Air75 II, where every gram and every aerodynamic detail contributes to flight performance and the overall flying experience.

Thanks to their optimised three-blade design, BetaFPV GemFan 1614 propellers generate greater airflow and thrust than conventional two-blade alternatives. The result is faster response to control inputs, smoother flight characteristics, and improved stability both indoors and outdoors. This makes them an excellent choice for pilots looking to achieve maximum performance from compact whoop-style FPV drones.

Engineered for Maximum Efficiency

BetaFPV GemFan 1614 propellers feature a 40 mm (1.6-inch) diameter and are manufactured from durable, flexible polycarbonate (PC). The material offers excellent impact resistance while maintaining the propeller’s shape and aerodynamic efficiency through everyday use. Weighing only 0.24 g per propeller, they help minimise the overall aircraft weight, improving flight time while reducing the workload on the motors.

The 1.0 mm shaft hole provides a precise and secure fit for popular 0802-series brushless motors. This helps minimise vibration while improving power transfer efficiency, which is especially important during aggressive manoeuvres and precise flight control.

Smooth Handling and Precise Flight Control

On micro FPV drones, propellers play a critical role in determining flight characteristics. BetaFPV GemFan 1614 propellers are designed to deliver consistent thrust throughout the entire throttle range, providing predictable handling and allowing the drone to respond quickly and accurately to pilot inputs.

The three-blade configuration improves airflow efficiency, producing higher thrust without a significant increase in power consumption. This translates into faster acceleration, more confident cornering, and greater stability even in demanding flight conditions.

Optimised for Air75 II

BetaFPV GemFan 1614 propellers are optimised for use with the Air75 II platform but are equally suitable for other micro FPV drones using 1.6-inch propellers and 1.0 mm motor shafts. Their transparent finish gives the drone a clean, modern appearance while complementing a wide range of frames and LED lighting setups.

The package includes four propellers—two clockwise (CW) and two counter-clockwise (CCW)—allowing for quick installation and convenient replacement.

Technical Specifications

BetaFPV GemFan 1614 propellers feature a 40 mm (1.6-inch) diameter, a 1.4-inch pitch, and a three-blade design. The shaft mounting hole measures 1.0 mm, while each propeller weighs approximately 0.24 g. They are manufactured from durable polycarbonate (PC), offering excellent impact resistance and a long service life. The package includes 4 transparent propellers (2× CW and 2× CCW).
