I found this originally on Facebook, but after I did a little searching I found a page in Russian. I link to the Google Translate Version of it below.
"In 1976 OSKB MAI-C was designed national economic light multipurpose aircraft "Elf" with a four-stroke air-cooled engine "Nelson" with capacity of 48 hp The device was made on a "nizkoplan" with a pusher propeller. I had a wingspan of 5.86 meters, takeoff weight of 330 kg. All-metal construction with longitudinal ribbed trim on the wing, tail and fuselage tail boom. "Elf" was a non-retractable trehstochnoe chassis with nose wheel and main stand spring type made of profiled titanium strip. The airframe was a lot of interesting discoveries and successful engineering solutions. several inventor's certificates obtained on the structural elements.
The main modification of the aircraft "Elf" - its manned version - had a streamlined cockpit with a large glass area and the right-side door. Behind the cockpit hood was installed in the engine "Nelson" with a two-bladed wooden propeller.
The first flight of the manned version took place in early August 1985, the DOSAAF airport in Borki. Experienced "Elf" Candidate of Technical Sciences Test Pilot E. Frolov. "
I think this would be a perfect little training plane if it could be made as a small 2 seater. If done right it could fall in the "Ultralight" class for the USA. Or even a Light Sport aircraft.
I know I would be very interested in one myself.
