The air-cooled Corvair engine has been widely used in homebuilt aircraft.
Some aircraft, such as the Pro-Composites Personal Cruiser have been specifically designed for them.
The defunct American company Hegy Propellers, which was based in Marfa, Texas, produced propellers specifically for Corvair engines.

A variation on the six-cylinder engine is an opposed-twin version based on the Corvair pancake six.
Some individuals have also experimented with inline-triple configurations based on half of a Turbo-Air six.
