Ruschmeyer Luftfahrttechnik initially designed the Ruschmeyer MF-85, intended to be powered by Porsche PFM 3200 derivatives, which was debuted at the 1987 Hannover Air Show. The MF-85 was a composite four seat aircraft, planned to be offered with 134 to 183 kW (180 to 245 hp) engines, priced at DM245,000 to DM325,000 (excluding avionics), with optional fixed or retractable undercarriage. The prototype (V001 D-EEHE) first flew with a 212 hp (158 kW) Porsche PFM 3200N, driving a 3-bladed Mühlbauer MTV.9 constant speed propeller, on 8 August 1988, piloted by Horst Ruschmeyer. The second and third aircraft, V002 (D-EERO) and V003 (D-EERH), on flew on 23 September 1990 and 12 February 1992 respectively. Despite promising flight test results, the unavailability of Porche engines led to the development of the Textron Lycoming powered R 90.

Powered by a Lycoming IO-540-C4D5 driving a Mühlbauer MTV.14-B constant speed propeller, the production R 90-230RG was built from 1988 to the mid-1990s in Germany. The engine is de-rated to 172 kW (231 hp) to reduce noise, but still enables the R 90 to reach a maximum cruising speed of 324 km/h (175 kn; 201 mph). German certification was awarded in June 1992. After a short production period Ruschmeyer Luftfahrttechnik filed for bankruptcy in 1996, however in 1999 Solaris Aviation was founded, and purchased the assets of Ruschmeyer, marketing the R90 as the Solaris Sigma.
