The Koolhoven F.K.30 Toerist was a small sport aircraft built in the Netherlands in 1927, intended for use by aeroclubs.

The fuselage carried the pilot and one passenger in tandem in a bathtub-like open cockpit.

The engine, driving a pusher propeller, was mounted on the aircraft centerline at the aft portion of the wing.

The wing, including engine, was designed so that it could be pivoted 90° while on the ground, allowing the aircraft to be stored and transported more easily.

The aircraft failed to attract the interest of buyers, however, and only the single prototype was constructed, with Koolhoven himself the only person to fly it.
