This is a tractor (not a pusher ) airplane propeller.
APC model aircraft propellers have been designed and manufactured in the USA since 1989. APC's blade designs are the most efficient and silent injection molded propellers on the market. Computer-optimized design gives these props a thinner profile and more bite with less noise. Lightweight molded nylon construction reduces rotating mass for higher output and longer life.
