Schönleber makes wings for other manufacturers as well as Schönleber trikes.
This big, strange ornithopter was designed by architect Bruno Scholz of Schulzendorf near Berlin after 12 years of studies of birds. It was “modelled after real birds” and the frame was made of bamboo sticks with multiple-slatted wings covered canvas. The apparatus measured from head to tail 17 meters, the wing span was 14 meters and the height 6 meters. The bird’s body held a cockpit for two passengers, two engines, each of 8 hp, and a centrifuge (fan?) which would help to lift it. It was built at great expense in 1909/10, but after it had been found to be complete failure it was reportedly smashed by hand by its builder.
In 1923, the British magazine Flight reported what it termed the first successful flight of an aircraft constructed in China. This conventional biplane was designed by a German engineer, Leopold Carl Ferdinand Friedrich Schoettler. Its engine, instruments, wheels and dope for fabric covering were imported from Europe. All else was locally sourced. Work on it began in the summer of 1922.
The Schoettler I was a conventional European style two seat tractor biplane, with equal span two bay wings. These were mounted with 2° of dihedral and 597 mm, almost 2 ft, of stagger. The gap between the upper and lower planes was 1,676 mm (66 in), maintained by parallel pairs of aerofoil section struts and wire bracing. The unswept wings had a constant chord of 1,600 mm (63 in) with blunt wing tips and ailerons on both upper and lower planes. The Schoettler’s empennage was also conventional.
The fuselage was likewise a standard rectangular section wooden girder structure, fabric covered except around the engine and a wood upper decking around the open, tandem cockpits for pilot and for the observer, who sat under the wing trailing edge. It tapered to a knife-edge at the tail. At the front the 160 hp (119 kW) Mercedes water-cooled upright inline engine was enclosed in a rectangular cross-section metal cowling which tapered vertically, exposing the upper cylinders, to a two-blade propeller. At the rear of the housing an external radiator, with shutters for engine temperature control, projected on each side. The Schoettler had a conventional fixed undercarriage, with the mainwheels on a rigid axle mounted on V-struts.
A first flight date was not reported, but this was on or before 23 July 1923 when the Schoettler was test flown by an ex-RAF pilot, W.E. Holland. The latter reported good handling and an excellent, 360°, field of view for the observer noting the aircraft’s potential for development. More recent articles claim the first flight by a Chinese built aircraft was that of the indigenously-designed Xianyi Rosamonde (or Dashatou Rosamonde) on 12 July 1923, though without mention of the Schoettler; the two aircraft were evidently close contemporaries.

In late 1923 Flight reported on what was claimed to be the first successful aircraft constructed in China. It was designed by the German engineer Leopold Carl Ferdinand Friedrich Schoettler (born April 7, 1881, in Bruchhausen-Vilsen, Germany; died September 27, 1948) but the only major components imported from Europe were the engine, instruments, wheels and dope for the fabric covering; everything else was locally produced from local materials by workers without aviation experience or modern machinery.
In 1928 K O Schneider of Long Beach CA., built a two-place cabin biplane, registered N6947 c/n 1.
It was powered by a 100hp Hall-Scott engine and noted in a magazine ad selling new for $450. It was purchased by Garland Lincoln
Long Beach CA.

Built a two-place cabin biplane in 1928.
The Frederick Schneider No.1 Biplane was shown at an exhibition at Morris Park called by the Aeronautic Society of New York at the end of 1908, where Schneider tested the biplane of 30 ft. span. Among the most notable of its features was a low total weight of only 450 lbs and the use of three aluminium propellers of variable pitch. The engine, an air-cooled rotary, caused the failure of these flights.
