Koolhoven F.K.30

__NOTOC__

The Koolhoven F.K.30 Toerist was a small sport aircraft built in the Netherlands in 1927, intended for use by aeroclubs. An unorthodox design, it carried the pilot and a single passenger in tandem a bathtub-like open cockpit. The wing was mounted parasol-fashion behind them, with the main units of the fixed undercarriage directly below it. The engine, driving a pusher propeller, was mounted among the wing struts, and the conventional empennage was carried on a boom extending below the propeller arc. The wing and engine installation was designed so that it could be pivoted 90° while on the ground, allowing the aircraft to be stored and transported easily.

Koolhoven had designed the F.K.30 for Nationale Vliegtuig Industrie, but when the company folded, he built it as the first product of his own company. The aircraft failed to attract the interest of buyers, however, and only the single prototype was ever constructed, with Koolhoven himself the only person ever to fly it. It was eventually sold to Clifford Harmon, president of the International League of Aviators, but when he never collected it, it was scrapped.
