History
The Koolhoven Fk46 was a two seat trainer and sports plane. The first prototype, a wooden biplane with open cockpits was built in 1933 and made the first flight in the autumn 1933. It was designed so that it can not be exaggerated, a convenient feature for training aircraft.
The aircraft was extensively tested by the NLS (National Aviation School) and eventually purchased, followed by an order for five aircraft. These had a fuselage of steel tube with linen and a different engine, a DeHavilland Gipsy Major I. The bonnet was a different shape. Further, a plexi glass was cockpit hood is placed over both cockpits, whereby also the rear end of the hull was increased.
