BetaFPV HQ 31mm Ultralight 3-Blade Props – Ultra-Lightweight Three-Blade Propellers for Micro FPV Drones

The BetaFPV HQ 31mm Ultralight 3-Blade Props are premium ultra-lightweight propellers designed for micro FPV drones, where every gram has an impact on flight performance and handling. Thanks to their carefully optimised three-blade design, these propellers provide an excellent balance of thrust, flight efficiency, and precise control. They are an ideal choice for Tiny Whoop drones as well as other 1S micro FPV platforms, where fast throttle response and smooth flight characteristics are essential.

With a 31 mm diameter, these propellers are manufactured from high-quality polycarbonate (PC), offering excellent durability for everyday flying while helping maintain their shape even after minor impacts. The translucent finish gives your drone a clean, modern appearance and pairs perfectly with a wide range of frames and electronic components.

Ultra-Lightweight Construction for Improved Flight Performance

The BetaFPV HQ 31mm Ultralight 3-Blade Props are engineered to achieve the lowest possible rotating mass. The complete set of four propellers weighs just 0.67 grams, reducing motor load while providing faster throttle response and more precise handling.

The reduced rotating mass also improves flight efficiency by lowering power consumption and helping to extend flight time. This makes these propellers an excellent choice for pilots who want to maximise the performance of their micro FPV drone without sacrificing efficiency.

Three-Blade Design for Smooth and Stable Flight

The BetaFPV HQ 31mm Ultralight 3-Blade Props feature an aerodynamic three-blade design that delivers an excellent balance between thrust and efficiency. Compared to two-blade propellers, they offer improved grip in the air and smoother flight characteristics while maintaining excellent power efficiency.

The three-blade configuration enhances the drone’s responsiveness during rapid direction changes, enables more precise manoeuvres, and helps maintain stability in both indoor and outdoor environments. As a result, these propellers are an outstanding choice for freestyle flying, practice sessions, and everyday FPV flights.

Durable Polycarbonate Construction

These propellers are made from premium-quality polycarbonate (PC), combining lightweight construction with excellent impact resistance. The material withstands minor crashes well and helps reduce the risk of propeller damage during normal use.

The 31 mm propeller diameter and 1.0 mm shaft hole ensure compatibility with many popular micro FPV motors. The precision-moulded hub fits securely on the motor shaft, reducing vibration and contributing to smoother flight performance and cleaner FPV video footage.

Perfect for Tiny Whoop and 1S Micro FPV Drones

Thanks to their lightweight construction and efficient aerodynamic design, the BetaFPV HQ 31mm Ultralight 3-Blade Props are ideal for Tiny Whoop, brushless whoop, and other 1S micro FPV drones. They deliver rapid acceleration, precise handling, and stable flight performance for both beginners and experienced pilots.

The package includes four translucent propellers, consisting of two clockwise (CW) and two counter-clockwise (CCW) propellers. This allows for quick installation and makes the set an excellent choice for replacement parts, new drone builds, or upgrading the performance of an existing micro FPV drone.
