A large, rounded, startlingly modern fuselage for its day, using what appears to be almost geodesic construction, with chain-driven twin tractor propellers.
During 1910 and 1911 this aircraft was built in a shop adjacent to Mineola Field NJ. The design was basically sound and the plane performed well beyond expectations. In Jan 1912, US Patent #596448 was granted to the aeroplane per notification from Munn & Co, Patent Attorneys, NYC.
This machine was tested in spring or summer 1911 at the flying ground Plauen-Reisig in Sachsen, Germany. It had a Taube-like top wing, a forward elevator, a chain driven pusher propeller and a small stabilizing plane on top the original tail-boom construction. According to Lange it was powered by a 65hp Hilz inline-4. There are thoughts that Schmelzenbach and Hollmann wanted to open a flying school and this plane was intended as a trainer, therefore being equipped with dual controls.
Ernst Schmalz, born 1879 in Nidau, Switzerland, in 1908 built with the help of Failloubaz, a pusher monoplane, powered by a 12 hp Anzani motor, with large ailerons he himself named “Stabiloklappen”. In flight tests at Thun he made jumps of up to a height of 6 meters. In 1909, Schmalz retired from flying. He sold his apparatus to a chauffeur, who collided with a tree top in flight tests on the Beundenfeld in Bern. Although the pilot remained intact, the aeroplane itself was a total loss.
Designed by Martin Heide, the tandem two seat Schleicher ASH25 featured the longest wingspan of any production glider (25 metres). First flown in 1986, the ASH25 first went into production in that year. Construction is all carbon fibre and the sailplane can sustain a glide angle of 1:58. The design was specifically aimed at producing a two seat glider with single seat perform¬ance and utilises the wing of the ASW22B married to a new fuselage of carbon/ aramid fiber reinforced plastic.
Within a couple of years the ASH25 had set five world speed records for triangular courses varying from 330 km / 205.1 miles to 1,380 km / 857.0 miles. Hans Werner Grosse of Germany has set 12 world records in all flying an ASH-25.
The ASH-25 is the production version of the one-off two-place ASW-22-2 using a fuselage adapted from the Akaflieg Stuttgart FS-31.
The ASH-25E is powered by a retractable 19 kW/ 25 bhp Rotax 275 sustainer engine.
A flight test evaluation by Dick Johnson measured a best L/D of 54.3 : 1 without turbulator tape or special sealing. An ASH-25 flown by G. Herbaud and J-N. Herbaud of France both won the world multiplace straight distance and goal distance records of 1,383 km./ 859.3 miles in the same flight in 1992.

The AS-K 16 is a side-by-side two-seater motor glider, with dual controls. The type is of mixed construction with a welded steel tube fuselage covered in fabric, plywood and glassfibre. The cantilever single-spar low-set wooden wings are fabric-covered with glassfibre tips and spoilers in the upper surfaces. The tail unit is of wooden construction with fabric covering, with combined trim and anti-balance tabs in the port elevator. The AS-K 16 has main wheels retracting inwards into the bottom of the fuselage, and a fixed tailwheel; the main wheels have rubber shock absorbers and Tost drum brakes. The pilots sit under a one-piece blown canopy that hinges sideways to open. Powerplant is a 72hp Limbach SL 1700EB1 modified Volkswagen ‘flat four’ engine driving a Hoffman HO-V 62 two blade variable-pitch propeller.
It first flew in prototype form on 2 February 1971 and first appeared in public at the second German Motor Glider Competition at Burg Feuerstein in June that year, but it did not compete.
An AS-K 16 flown by Hans Werner Grosse and Ing R. Kaiser took third place in the First International Motor Glider Competition in 1974.
By January 1976 38 AS-K 16s had been built, but it is now out of production.

This single-seater motor glider was originally known as the Ka 12 and was designed by Ing Rudolf Kaiser but, to avoid confusion with the AS-W 12 high performance sailplane which was also built by Schleicher, it was redesignated AS-K 14.
Of conventional wooden construction, it has what is basically a Ka 6E’s semimonocoque fuselage with plywood covering married to low-set cantilever wood and fabric wings with 5° dihedral, similar to the Ka 6E’s and with the same aerofoil section; the single-spar wings have spoilers in the upper surfaces and plywood-covered ailerons. The pilot sits under a large one-piece blown Plexiglas canopy that hinges sideways to starboard, and the landing gear consists of a manually retracted monowheel on a leg tall enough to give adequate ground clearance for the propeller, plus a tailskid. Powerplant is a 26hp Hirth F10 K19 ‘flat four’ two-stroke engine in a conventional tractor installation driving a two-blade Hoffman feathering propeller; starting is manually. The tail unit is of wood/plywood/fabric construction, with a low-set all-moving tailplane.
The prototype made its first flight on 25 April 1967, and the type took second, third and fourth palces in the first at Burg Feuerstein in the German Motor Glider Competition, which was held in 1970; in the sixth of these competitions, in 1976, the AS-K 14 was still good enough to take second and third places.

Robert Schlageter of Luzer, Switzerland, was born in 1887. He quit his technical studies in Burgdorf to devote himself to aviation. After first tests with gliders, he began to build, with the help of two friends, his first monoplane, with a triangular-section fuselage and an Anzani engine, in 1909. Then he built in four months, for a company in Mainz, another monoplane of the same type. His planes flew only in good wind conditions, but he won a prize at a fair in Chemnitz in 1911. He had to quit aviation for economic reasons, was forced to sell his planes and spare parts.
In 1917 Schiefer & Sons Aeroplane Co built the RS, designed by N B Robbins. A Pursuit trainer based somewhat on French V-strutted Nieuport design, it first flew on 9 December 1917.
The sole example was bought for a reported $11,000 and tested by the Army, but rejected as not being as good as Orenco or Thomas-Morse.
