High-wing pusher monoplane powered by an opposed 4-cylinder Oerlikon engine rated to 45 hp. Henri Kunkler, born in St.Gallen 1886, was one of the young aviators in Switzerland. He flew since 1911 (Blériot) and in 1912 he completed his own monoplane that he built with his mechanic Rossier. Rossier obviously played an important role in the design but was neither financier, owner or pilot. The first noteworthy adventure with that machine was the cross-coutry flight from St-Gallen to Dübendorf on 4. September 1912 (ca. 60km in 12:30h with two emergency landings). Kunkler flew this craft until he gave the controls to Ernst Rech in May 1913, who would take part at the Meeting in Olten. He decided to move the plane by a cross-country flight but lost control in strong winds and crashed to his death.
