This plane, the first Swiss two-seater, was a 1911 development of the earlier Dufaux-4 and had a similar landing gear and triangular-section fuselage. It was equipped with either 70 hp Gnôme or with Oerlikon 4-cylinder horizontally-opposed engines. Several were built, it was used in the flying school of Ernest Failloubaz, was flown by many of the most famous early Swiss pilots and also made the first Swiss military flights.

The first of several gliders tested by designer/builder Albert Q. Dufour, “not yet 20 years old”, in Milwaukee, Wisconsin, USA. It was launched from a 40 feet inclined runway ending 15 feet off the ground in 1907 and made flights of up to 100 feet.
The 1909 Dufaux tractor biplane made many flights during 1909 and in 1910. Armand Dufaux flew almost 50 miles in 1 hr 18 mins over water the length of Lake Geneva (almost double the distance over water than Bleriot during his channel crossing)

Built in Switzerland in 1909 by the Dufaux brothers. An ambitious concept for the time, the Tiltrotor was not successful.
In Switzerland, on 28 August 1910, Armand Dufaux flew 80 km over the Lake of Geneva in the aircraft built by his brother Henri and himself.
The Dufaux brothers of Switzerland built an unmanned 23 kg “proof-of-concept” scale model, powered by 3.1 hp motorcycle engine. It was flown as a kite in 1905 and led to a full-scale tilt-rotor machine that was tested in 1909.
First airplane designed and constructed in Brazil – 100% made by Dimitri Sensaud de Lavaud; even the propellers and the engine were manufactured by him. It first flew on January 7, 1910 at Osasco: 6 seconds for 103 meters; also considered to be the first flight by an aircraft of complete South America design and construction.
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 feature pilots were reluctant to fly. Eventually Drzewiecki designed improved version, but outbreak of World War I stopped further development.
