High Quality Content by WIKIPEDIA articles! The Schweizer 300 (formerly Hughes 300) family of light utility helicopters was originally produced by Hughes Helicopters, as a development of the Hughes 269. Now manufactured by Schweizer Aircraft, a recent subsidiary of Sikorsky Aircraft, the basic design has been in production for almost 50 years. The single, three-bladed main rotor and piston-powered Schweizer 300 is mostly used as a cost-effective platform for training and agriculture. In February 2009, the 300C was rebranded as the Sikorsky S-300C.
