Propeller 45mm two-blade for micro drone, BETAFPV RD45MM2BL, pack of 8

BETAFPV two-blade 45 mm propellers (pack of 8) are lightweight replacement props designed for micro FPV drones, cinewhoops and micro quads. The RD45MM2BL model features a compact 45 mm diameter and a two-blade layout optimized for small brushless or brushed motors. These propellers are intended as spare or replacement parts to restore lift, maintain stable hover characteristics and preserve responsiveness during indoor and close-quarters flying.

Advantages

The two-blade design provides efficient thrust and predictable airflow for precise control in tight spaces. Made from lightweight durable plastic, the propellers offer a balance between stiffness and flexibility to resist minor impacts while keeping overall weight low. Supplied as a pack of eight, they allow multiple replacements or spares for multi-rotor builds and routine maintenance.

Suitable for

• Micro FPV drones and micro quads with 45 mm class prop mounts
• Cinewhoops used for indoor or close-proximity filming
• Brushless or brushed micro motors where two-blade 45 mm props are specified
• Replacement or spare parts for repair and routine maintenance

Key specifications

• Diameter: 45 mm
• Blade count: 2 blades per propeller
• Material: lightweight durable plastic
• Pack quantity: 8 propellers
• Compatibility: designed for micro-class motors and frames

How to use

Fit the correct propeller orientation to each motor according to your drone's motor rotation (clockwise or counterclockwise). Ensure propellers are seated securely on the motor shaft or adapter and tighten any locking hardware to manufacturer torque specifications. Inspect propellers for damage or deformation before each flight and replace any chipped or bent props to maintain predictable handling and reduce vibration.

Recommendations

For best performance, use these 45 mm two-blade propellers on micro quads and cinewhoops with matching motor shaft fittings and recommended RPM ranges. Regularly check for wear after minor impacts and keep several spares from the pack available to minimize downtime during repairs.
