This machine was built for the inventor, Erhard Brunsmann of Berlin-Eichwalde, Germany, by Edmund Rumpler in Berlin-Johannisthal. The tandem wings were driven by a complex patented crank mechanism and it was intended that control would be achieved by differential flapping of the wings, rather than by separate control surfaces. Lange dismisses it in little more than two lines as a “Fehlkonstruktion”.

Built by the “Fabbrica Italiana di Aeroplani” of Turin, Italy, in 1910. Claimed to be well designed but too heavy.

The “Brumah I” was the first machine built by the two seventeen-year-old Harry A. Bruno and Bernard H. Mahon (hence the name) of Montclair, New Jersey, crashed on its first flight from the barn. The Brumah II, with a span of only 16 feet, was called the world’s smallest monoplane. It was flown on sled runners down an ice-coated hill on Christmas Eve 1910. It crashed then too but might have been re-built, but there is no indication that it was ever actually fitted with a motor.

The 1909 BRT biplane was built in France.

Carl Dryden Browne, formerly one of the “generals” in the famous Coxey Army of unemployed men who marched on Washington in 1894, built what he called an octoplane. It was equipped with a stationary elliptic plane, running lengthwise of the machine, measuring 4 feet at its widest part and tapering to a point at each end, designed to act as a stabilizer. The motive power was furnished by a 30-horsepower motor, operating a tractor propeller and two large four-bladed revolving planes on each side, similar to the paddles of a sidewheel steamer. The span of the machine was 26 feet and the length 28 feet. The elevating and vertical control surfaces were similar in shape and operation to those of a standard Curtiss.
