The aircraft was originally conceived as a retractable engine motor glider, to be a competitor to the Albastar Apis, but instead it was put into production as a conventional unpowered glider.[1][2]

Design and development

The company states the design goal of the AC-6 as a glider for the competition and training roles, even though it does not have provisions for water ballast.[2]

The AC-6 is a 15 m (49.2 ft) wing span development of the 12.6 m (41.3 ft) span AC-5M, with longer, higher aspect ratio wings terminating in winglets. Like the AC-5, the AC-6 wing employs a Wortmann FX 60-157 airfoil. Assembly of the wing to the fuselage uses a cam pin and incorporates automatic hookups for the ailerons and air brakes. The landing gear is a retractable 360 mm (14.2 in) tire monowheel gear suspended with a pneumatic-hydraulic shock absorber. The wheel has a lever and cable operated drum brake. The cockpit can accommodate pilots up to 190 cm (74.8 in) in height. The canopy provides 300° field of view and is jettisonable.[1][2]

A two-seat version was also proposed.[1]
