This two-seat aerobatic biplane is stressed to a +6G and -3G limit, and +9G to -4.5G ultimate. It was first flown in 1973, and its designer, Edwin Merkel, planned to produce the biplane in a two-seater trainer version and a single-place competition model. The Mark II is completely covered with a light alloy skin outside, and underneath the fuselage is welded steel tube while the wings feature a single-spar tor¬sional structure. Other extras include an antiservo tab, ground-adjustable trim tab and optional cockpit canopy.
