RMT Aviation Bateleur

TerryLeave a comment

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.

RMI RMI-9 M/G

TerryLeave a comment

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.

RMI RMI-7 V/G

TerryLeave a comment

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.

RLU RLU-1 Breezy / Breezy Aircraft RLU-1 Breezy

TerryLeave a comment

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.

RLU RLU-1 Breezy Article

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.
