The first of Emil Jeannin’s monoplanes, the 1912 Eindecker Typ A design was the basis for all Jeannin’s Eindecker before the Stahltaube. It was sold with a 50/70 hp Argus, or a Gnôme engine.

JDM Roitelet (Wren)
A single-seat ultra-light monoplane. Poinsard-engined prototype flew successfully, but lack of suitable production engine prevented manufacture and by 1951 company had been dissolved.
Jay Souza Gyroplanes Super Bandit
A pilot of up to 250 pounds can comfortably jump aboard the Super Bandit. The single-seat, opened-frame can be equipped with a 94-hp EA-81 Subaru engine or it can morph into an ultralight with a 55-hp 503 Rotax engine. With the Subaru, it can reach 85 mph and with the Rotax, 63 mph. Useful load is 313 pounds with the Subaru or 348 pounds with the Rotax.
Kit prices in 2001 were:
Basic kit (without engine, instruments and propeller): $7500
Deluxe kit: $11,000
Jatho Stahltaube
The 1911 Jatho “Stahltaube” (“Steel Dove”) monoplane was designed and built by Karl Jatho in Germany.
Jatho V
This 1910 Jatho Eindecker was first fitted with a 35 hp Koerting engine. It is likely that this Blériot-inspired monoplane was later identified as the Jatho V, later fitted with an Argus engine.
Jatho VI Eindecker
Not much is known about this pusher, which was designed by pioneer Karl Jatho (1873-1933) of Germany. It had a 50 hp Argus engine, a wing span of 11.8 m and a maximum speed of 70 km/h. It was built by the Hannoversche Flugzeugwerke GmbH in 1910 and was reported to fly well.
Jatho Motordrachen / Doppeldecker / Zweidecker I
Rebuilt from Karl Jatho’s earlier Dreidecker, which had been damaged on August 21, 1903, the Jatho Doppeldecker “Motordrachen” of 1903 was powered by a 9-12 hp Buchet motor, belt-drive pusher propeller.
Two Germans, Gustav Weisskopf and Karl Jatho, made the first motorized flight on August 14, 1901 with a 21-horsepower monoplane with 12 horses, a flight of 850 meters. The second was a similar performance on August 18, 1903.
It is on the moor of Vahrenfelder, that Karl Jatho flew 18 meters, rising to 1 meter of height, with his biplane type “Zweidecker I”. The propulsion was from a two-bladed propeller and single-cylinder Buchet engine of 9 horses.
Engine: Buchet, 9-12 hp
Wingspan: 8 m
