[1] The M.218 was of plastic and metal construction; the wing spar box and the rear lower fuselage were made from aluminium alloy which formed a T-shaped load bearing structure which carried the metal tailplane and all the plastic components.
[3] It was powered by two 145 hp (108 kW) Rolls-Royce Continental O-300 piston engines and had a retractable tricycle landing gear.
[1] Registered G-ASCK[4] it was displayed at the 1962 Farnborough Air Show priced at £9,800, it did create interest from customers although they had a preference for metal built aircraft rather than the plastic M.218.
[1][3] The majority of the glass fibre components were replaced in light alloy, which incorporated the original T-frame structure, with more powerful 195 hp (145 kW) IO-360 engines fitted.
[1] The aircraft was issued with a certificate of airworthiness on 18 June 1965 but the company was focussed on the production of the twin-engined Beagle B.206 and the design of the single-engined Beagle Pup and could not afford to further develop the type or put it into production, although a second airframe was commenced.
