Helio Aicraft Corporation was founded as Koppen-Bollinger Aircraft Corporation by Otto Koppen and Lynn Bollinger in 1948 with headquarters in Massachusetts. Its expertise is in manufacturing short takeoff and landing (STOL) utility aircraft. The Koppen-Bollinger Aircraft was renamed to Helio Aircraft Corporation when Helio Courier was put into production in Pittsburg, Kansas.

In 1969, Helio was acquired by the General Aviation Corporation and was renamed as Helio Aircraft Company. It was then bought by the Helio Aircraft LTD, then finally, by the Helio Aircraft LLC situated in Prescott, Arizona.

Here is one of Helio’s Aircrafts:


The Helio Courier is a utility aircraft designed in 1949 and comes in two versions: the conventional takeoff and landing (CTOL) or the short takeoff and landing (STOL).

Around 500 of the Courier had been produced by the original Helio Aircraft from 1954 to 1974. Helio Aicraft LTD has returned the production of the Courier in the early 1980s but only 18 were produced. When the Helio Aircraft LLC took over, it ensured the return of the Courier.

The Helio Courier had been used for civilian transport by American Air, JAARS, North-Wright Airways, and for military purposes as well by Bophuthatswana, Italy, Thailand, Peru, and the United States.

Numerous variants of the Helio Courier were produced. Some of these are:

  • 1. H-392 Strato Courier – high-altitide version

  • 2. H-500 Twin Courier – twin-engined variant used by the CIA
