Two-seater Biplane (dual control)

B.A.T. F.K.24, Baboon
THE Baboon was a small two-seat training biplane, in the design of which Koolhoven had aimed at ease of production and interchangeability of components. The fuselage was a very simple box structure with a rounded top-decking which was the only concession to aesthetics or aerodynamics in the entire design. The fuselage was considerably strengthened by its plywood covering. The A.B.C. Wasp radial engine was mounted on the flat-nose bulkhead and was innocent of any pretence at fairing; the interplane and centre-section struts were plain steel tubes without fairings; and all flight surfaces were straight-edged and square-cut. The undercarriage was the same wide-track, split-axle type used on the Bantam.
Interchangeability of components was held to be a desirable feature of trainer aircraft, which could be expected to suffer more damage than other types. Koolhoven, with typical ingenuity, carried the idea almost to its extreme in the Baboon: not only were the upper and lower mainplanes interchangeable, but the ailerons, elevators and rudder were all identical surfaces.
The Baboon was not officially adopted, but survived the Armistice and went on the British Civil Register as G-EACO.

Although not pursued beyond the prototype phase, the 1918 BAT FK 24 Baboon two seat trainer, built to an Air Board requirement, is of interest in terms of its choice of engine, along with aspects of its structure. Its power came from the specified 170hp ABC Wasp I radial, an indication, albeit later shown to be ill-judged, of the faith officialdom placed in the ABC radials. The Baboon's structure was not just robust, it was deliberately designed to use as many interchangeable components as possible, including the ability to switch upper with lower wings, plus being able to swap port and starboard elevators with the rudder. The machine's extra wide wheel track is also notable. Top level speed of the Baboon was 90mph at sea level, while climb to 10.000 feet could be achieved in 12 minutes. Seen here is serial no D 9731, the first of six ordered and the only one believed to have been completed.
