Master Airscrew MR Series 12x4.5 Prop Set, Black
by Master Airscrew

The Master Airscrew MR Series 12x4.5 Propeller Set is a premium propulsion solution engineered for the most demanding VTOL drones, professional multi-rotor platforms, and industrial sUAS. This matched set is specifically optimized to provide outstanding efficiency in both hover and forward flight, making it a top-tier choice for commercial drone operators, government agencies, and STEM educational programs that prioritize flight endurance and platform stability.

Manufactured from high-quality Glass Fiber Reinforced Composite (GFRC), these propellers offer superior strength and durability compared to standard plastic alternatives, ensuring they maintain their aerodynamic profile even under high load. Every propeller is factory-balanced to exceptionally tight tolerances (less than 0.01g), which is critical for reducing motor stress and eliminating high-frequency vibrations. This low-vibration profile is essential for capturing professional-grade, wobble-free aerial cinematography and protecting sensitive onboard electronics.
