The Aviatika-MAI-890А autogyro is a further development of the Aviatika-MAI-890 serially produced aircraft family. The high continuity of an aircraft structure allows the owner of the aircraft to install the «autogyro set», instead of wings himself. That is to replace wings with the main lift rotor. Thus, it receives a autogyro having a usual stereotype of the aircraft control. Besides, the opportunity of convertible transition back to the aircraft is preserved. The possibility of fast folding the main lift rotor frame and blades allows to minimize aircraft dimensions considerably, simplifying its storage and transportation.
