This machine was tested in October 1904, pulled by an automobile, but when the car reached a moderate speed the plane lifted, but a gust of wind tipped a wing so that the wheels on the opposite side were crushed. As a substitute, ordinary boards like skis were used, but then the car stalled without getting the plane off the ground, so horses had to be used. A team of draft horses pulled the rope and caused the plane to soar as high as the tree tops. Its builder Albert Rupel of Indianapolis, Indiana died of lockjaw less than a year later after stepping on a nail, before he could test it with a proper engine.

In 1910 Rumpler built monoplanes for several designers, which included the Eggers, Pegelow and Haefelin Eindeckers. All were powered by the Rumpler 50 hp Aeolus engine and all did not fly.

Designed by Swiss Emile Ruchonnet in 1911, this monoplane has a fuselage made up of long strips of citron wood which formed a monocoque shell. Ruchonnet founded a flying school at the “Aérodrome de la Vidamée” at Curteuil, north of Paris. He was killed in this machine, in January 1912, when attempting a cross-country flight.

Shortly before the outbreak of the Great War, student Jerzy Rudlicki (who later become known aircraft designer), after building several successful gliders 1912-1913 designed an aircraft named R-I. Its construction commenced with support of the Aero Club of Odessa (where Rudlicki resided at that time), which supplied Anzani engine. When the war erupted the plane was nearing completion and was therefore requisitioned by the Russian military which finalized the construction and made several (3 or 4) flights on it (before the plane crashed due to engine failure).

Designed by the Czech engineers Rozum and Bechyne and built by Emil Rudawski and Co. in Krakow. The construction of the aircraft was completed in April 1910. It was equipped a 40 hp air-cooled radial engine of their own design, one of the first Polish aircraft engines. It was presented at the factory on 4 April and the first flight was announced on 5 May.

In 1910 Pole Rozum and Czech Bechiny built in Kraków, Poland, an aircraft broadly modelled after Bleriot XI and with engine of their own design. Static tests of the engine and airplane were apparently successful, but it’s unclear if there were any flights made on it.
