Design and development A manufacturer of rigid wing hang gliders, Aerola decided to produce an ultralight sailplane along similar concept lines. The resulting aircraft is offered with and without a retractable engine. The prototype glider was known as the AL-12, with the motorized prototype designated as the AL-12M. The production versions are the Alatus and Alatus-M, respectively.
The aircraft is made from composites. Its span, slightly forward-swept wing has an area of . The landing gear is of a bicycle design, with a main wheel and a nose wheel, plus wing tip skids. The bubble canopy is in one piece and is removable. The light wing loading and low stall speed mean that the aircraft can be flown in the smallest thermals. The wings can be removed for ground transport on top of an automobile, while the fuselage is small enough to fit inside a van or to be secured to a small trailer.
