This Argentine single-seater motor glider was designed and is being built by Senor Augusto Lanzalone of Rosario in Santa Fe province, who has also formed the Asociacion Argentina de Constructores de Aviones Experimentales – Avex for aircraft like the Aulanz. Not only has Senor Lanzalone designed and built the engine for it – a 30hp Lanzalone two-cylinder two-stroke inverted inline motor of 700cc – he has evolved his own special alloy for the construction of the airframe. This is known as Alcusing, and consists of aluminium with portions of copper, nickel, magnesium, silicon and chrome; the two-blade variable pitch propeller is also made of this material.

The Aulanz is a conventional low-wing monoplane of semi-monocoque Alcusing structure, with the engine in the nose and a retractable rubber-sprung monowheel under the wing leading edge, plus a tailskid. The total fuel capacity is 20 litres (4.4 Imp gallons). By the spring of 1973 the prototype’s fuselage and tail unit were completed, and construction of the remainder had been proceeding slowly.
