Histoire résumée | Après la construction des deux prototypes du Moore Gypsy par Birmingham Guild Ltd. (BG-100/12 en 1970 et BG-100/13.5 en 1971), cette même firme mis le Gypsy en production sous le nom de BG-135. Birmingham a construit 4 exemplaires du Gypsy BG-135 [7 selon d'autres sources] The first pre-production Gypsy, the BG 135, flew in March 1972. It differed from the earlier versions chiefly in its wing construction, having the foam-stabilised thin skin of the BG 100s replaced by an aluminium alloy skinned D-box leading edge, based on the main spar, and with fabric covering between main and rear spars. The best glide angle of the BG 135 is 33:1. It gained a Certificate of Airworthiness in July 1972. After demonstrations at the British National Gliding Championships, held from 27 May to 4 June 1972, the BG 135 was loaned to several Clubs for evaluation. Following some minor modifications, production of a batch of seven was prepared. However, the sailplanes flying qualities were not well received and in 1973 Yorkshire Sailplanes bought the rights to the BG-135. Renamed the YS-55 Consort, production began in September 1973, the company at first completing four of the original Birmingham Guild aircraft. Some changes were carried out to the original design, notably in the fuselage profile, and the flying controls operated by rods instead of cables. | ||||||||
