A-20 is a new generation ultralight airplane designed on the basis of rationality-and-efficiency approach. As a result it became a award winner at several European and World Microlight Championships thanking to its characteristics.

A-20 features mixed structure (metal wing and tail, fuselage pod of composites) each component designed to serve best to its purpose at minimum weight and required strength and durability. The general design of A-20 was such a success that it served as a good prototype for several modified versions.

A-20 "Sky Cruiser" - modification of the basic version with a shorter span of the wing and tailplane, more powerful (80 hp) engine enclosed in a cowling, variable pitch propeller, fully balanced control surfaces, more streamlined landing gear and wing braces. Its design goal was to obtain an ultralight with good cross-country performance at the same time preserving the safe low-speed flying capabilities of the basic version.
