Described by its manufacturer as an “experimental ‘Three Passenger Airplane’ to demonstrate the high lift capability of an aircraft equipped with ‘Turbo Wing Technology.'” The Rotor Wing Ultra-Stol N25RW was developed in California in the late-1970s. It was reported as the Ultra-Stol by a company named Rotor Wing System and reportedly the aircraft flew at least twice.
Note the second engine and propeller, vertically mounted behind the trailing edge of the wing.
It had a relatively small wing and engines were reported as two Continental C85s and the rear could be tilted.
A very similar aircraft (maybe a rebuilt of the first?) was photographed in 1984 at Brown Field (near San Diego Ca), but it did not show a registration and was almost certainly never really completed. It differed in having a new wings, possibly from a Cessna Ce.150 and small canards. A company named High Technology Aircraft System, Inc (also in California). may be connected with this aircraft.
