Gemfan 51477 3-blade Hurricane Propellers are optimally designed for high-speed racing and long-range rigs, providing both efficiency and extended flight times. The inverse tip design minimizes blade tip vortex, while the lightweight construction ensures a low moment of inertia and quick response.

The format of Gemfan’s numbering scheme 51477 normally would mean 5.1″ Diameter x 4.77″ Pitch, but in this case, and the case of 51466, it’s merely a model number. As the actual pitch is 3.7″ and 3.6″ respectively (in the case of 51466)
