This machine was the brainchild of a Frenchman, Henri Robart. Completed and tested at Amiens in December 1907, it apparently even supported itself in the air on December 21.
This machine has an upward curving main lower wing, an upper wing and 50hp Antoinette engine on the fuselage which drove two tractor props via chain transmission.
It was never heard of again.
The configuration of the Bateleur brings numerous advantages compared to the conventional high or low winged aircraft. Its flight and handling characteristics remaining standard allows any pilot instant conversion.
The tandem seating for 2 people gives both pilot and passenger full view to both sides. The concept has proven to be stable in severe turbulence, comparable only to aircraft many times its weight making it very suitable as an aerial photographic or observation platform. The endurance and range in excess of 7 hours / 1000 km can be extended with auxiliary tanks by another 50%. As an Ultralight, the MTOW is 450 kg.

From 1943 the Air Force was gradually getting the Bf-109 advanced jet fighters (F and G versions), but it was not easy to get used to the tight and narrow track undercarriage. The Aero Technical Institute created the RMI-9 M/G specifically for the Messerschmitt pilots in training. The machine was designed with slats, so as to better mimic the Bf-109 flight characteristics.
Designed by Varga László, the RMI-9 M/G [or Me/G] Bf-109 pilot trainer was built but destroyed by US bombing in 1944 in the Ferihegy experimental hangar.

The RMI-8 X/V twin-boom, twin DB605 fighter was designed by Vilmos and Dezso Marton (assisted by László Varga), was also called the Marton X/V after the designers.
The two wings joined to the tail section, which is designed to incorporate the connection points of the high-powered MK-108 (30mm) deck gun.
The prototype (X/V-01) was said to have been destroyed by bombing while the airframe was still incomplete in April 1944.

The RMI-7 V/G was a side-by-side trainer powered by an Argus As.410, and equipped with retractable undercarriage. The mixed wood-built machine with torsion wings and hydraulic main landing gear had the same structure as the RMI Z / G.
The V / G was designed from the start serial production. Designed by Varga László and Rácz Elemér, a prototype was built in 1944. In 1944 the prototype was shipped to the Budaörs airport in order to fly but possibly never flew.

Designed and constructed by Charles Roloff, Carl Unger, and Bob Liposky, the Breezy was first introduced in 1965, and hailed as one of the most distinctive and unusual homebuilt designs to ever attend an EAA Fly-in.
The original Breezy was designed and built to accept a set of PA-12 wings. For that reason, there are no wing drawings with the plans. It is possible to substitute Champ, Taylorcraft, PA-14, PA-18, or J-3,4, or 5 wings. It’s also possible to order wing kits that replicate a J-3 wing. Breezy’s fuselage is an open framework steel tube truss. It is a three-place airplane with two seated abreast on the second seat, but it could easily be adapted as a single-seater or tandem two-seater.
Power for the prototype, which now hangs in the EAA Aviation Museum in Oshkosh, WI, is a Continental C-90. The original design utilizes a Piper Super Cruiser wing.
