Design and development

The Flyer was a very early ultralight design that first flew in 1970. 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. The Flyer is a very light and simple aircraft with a standard empty weight of only . It features a completely open cockpit with the pilot exposed to the slipstream. Unusually for this period in aircraft history when most ultralights had two-axis control, the Flyer has standard three-axis controls, including half span
