Design and development

The Donald is a conventionally laid-out single engine, braced high wing monoplane. Its low aspect ratio (5.1) wings are unswept and of constant chord, with blunt, rounded tips; they carry short, broad ailerons but no flaps. There are V-form struts between the wing and lower fuselage on each side. At the rear the vertical surfaces are rounded and the balanced rudder extends down to the keel. The horizontal tail is tapered with rounded tips and the elevators have a cut-out for rudder movement. [1]

Behind the engine the fuselage is flat sided. The pilot's windscreen is just ahead of the wing leading edge but the side glazing of the single-seat cabin extends back to about two-thirds chord. The cabin roof extends into raised rear fuselage decking, which drops away slowly to the tail. The Donald has a tailskid undercarriage with main wheels mounted on split axles, hinged on a shallow V-strut attached to the fuselage underside. Faired, tapered legs are mounted on the lower fuselage longerons.

The first prototype, with only 19 kW (25 hp) from its Volkswagen 1.1-litre air-cooled flat-four engine, first flew on 16 June 1953. Two other Donalds were homebuilt from plans by different amateurs. These were chiefly distinguished by the choice of air-cooled flat-four engine, most of which were Volkswagen based. Engine details, dates and type numbers are given below. [1] The last built, the CP-402 no.9 F-PRAK, was still on the French civil register in 2014, [2] having moved to Angers in 2005. [3]
