Propellers for FPV Quadcopter Gemfan Hurricane 51466 V2 MCK, 3-Blade, 5-Inch, Set of 4 pcs (Original)

High-performance general-purpose propellers for multirotor systems, recognized as the standard in high-speed FPV flying. The second revision of the Hurricane 51466 series features a reinforced blade root and a refined wing leading edge. This reduced drag, increased overall thrust at high RPM, and eliminated air slip during sharp pull-outs from dives. The high-quality polycarbonate lets the propellers bend rather than break in minor crashes and contact with branches, so the pilot can straighten the blade in the field and continue flying. The propellers are factory-balanced, minimizing parasitic mechanical vibrations (jello in the camera).
