Designed by Alberto Morelli, the M-300 is a high performance single-seater intended not only for club use but for competition and record flying, and to this end particular attention has been paid to structural design and techniques both to reduce the time taken forcontruction and to ensure the necessary accuracy and quality of surface finish.
Only two prototypes of the M-300 were in the end built and flown at the CVT (Centro di Volo a Vela del Politecnico di Torino) at Turin, the first making its maiden flight in April 1968. The shoulder wings are of composite construction, the tapered wing spar being a machined aluminiumzinc alloy section beam with lightening holes in the web, and the ribs are milled out of a wooden sandwich, the wing skin being of thick pre-formed plywood panels. The fuselage is a semi-monocoque wooden structure with four main frames and nine stringers, and with a glassfibre nose cone; wing/fuselage attachment is by means of Redux-bonded dural fittings. The rudder is double-slotted and the all-moving tailplane on top of the fin is a narrow chord one-piece aluminium alloy structure. A retractable monowheel is provided.
