Design and development

The AC-5M is derived from the motorized version of the Aviastroitel AC-4 Russia. Its design goals were to produce a simple and inexpensive self-launching sailplane. It had its first flight in December 1999 and production commenced in 2000 with a total of 35 completed. [1] [2]

The AC-5M features a 12.6 m (41.3 ft) span wing that employs a Wortmann FX60-157 airfoil. The wings are mounted on the fuselage with a single cam-pin and the ailerons and air brakes hook-up automatically. Assembly can be accomplished by one person in five minutes. The engine is a 19 kW (25 hp) Zanzottera MZ-35R, which is a special narrow engine design developed specifically for retractable engine motor gliders. The engine retracts rearwards into a bay behind the cockpit and is closed by two doors for drag reduction. The propeller is a two bladed wooden design of 1.18 m (46 in) diameter. The landing gear is a retractable 310 mm (12.2 in) monowheel gear with a lever-actuated drum brake, but without suspension. 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] [3]

In 2003 the aircraft sold for US$33,000. [1]

Operational history

In October 2011 there were 22 AC-5Ms registered with the US Federal Aviation Administration and one registered with Transport Canada. Because the aircraft was never type certified all American examples are in the Experimental - Racing/Exhibition category, while Canadian are in the Limited Category. [4] [5]
