Aeronautics was also among Stefan Drzewiecki's interests. His works regarding aircraft stability led to building in 1911-1912 a "self-stable" aircraft in canard layout. Interesting feature of the plane was lack of typical steering areas - altitude was adjusted by changing engine power while turning was done by adjusting AoA of either half of the nose wing. First flight was made in 1913, but because of this unusual steering features pilots were reluctant to fly. Eventually Drzewiecki designed improved version, but outbreak of World War I stopped further development.
