FK 54 с подкосным крылом типа парасоль, трехместной кабиной и мотором Gipsy Major мощностью 140 л. с. предназначался для частных заказчиков, однако таковых не нашлось.
The Koolhoven F.K.54 Three-seat Cabin Monoplane (130 h.p. D.H. "Gipsy-Major" Series II engine).
A REFINED KOOLHOVEN: The high-wing monoplane is notoriously bad for purposes of wheel retraction, but Mr. Koolhoven, in an effort to produce a three-seater tourer with good vision and a high performance, has resorted in the FK54, to the arrangement illustrated here, the wheels of course being tucked into the fuselage. With a Gipsy Major Series II the top speed is 155 m.p.h.
