Landing Products of Knights Landing, California, USA is the maker of APC (Advanced Precision Composites) model airplane propellers, so named because they are made from a composite of nylon fibers and carbon fibers.
Founded in 1989, Landing Products' propellers are among the most popular not only for pattern and racing, but for casual flying as well. They work closely with competition flyers in order to constantly improve their product.
More than 300 APC propeller sizes are currently available, both slow flyer and direct drive with sizes added on a regular basis. Current two-blade sizes range from 5.5x2 to 26x14. Their recently expanded manufacturing capability now permits injection molding of even larger single piece propellers, including two- and three-blade versions.
