The Kolb Flyer is an American single seat, high wing, strut-braced, twin-engine, pusher configuration, conventional landing gear-equipped ultralight aircraft that was produced in kit form by Kolb Aircraft of Phoenixville, Pennsylvania, and intended for amateur construction.
The first aircraft designed by Homer Kolb, it was ahead of its time and was not produced commercially until 1980, when the ultralight boom hit North America.
[1] When the Flyer was designed there were no suitable lightweight engines available, so the prototype aircraft first fitted Chrysler powerplants.
The horizontal stabilizer, tail fin and wings are also constructed of riveted aluminum tubing with all flying surfaces covered in doped aircraft fabric.
[1] The Flyer was later improved and developed into a single engine aircraft, the Kolb Ultrastar, which succeeded it in production in 1982.
