The SF-36 two-seater motor glider was developed from the SF-H34 and uses the letter's wings and tail unit married to a new fuselage, seating two side by side instead of the SF-H34's tandem seating. The wings are low-mounted with Schempp-Hirth air brakes, and are detachable for hangarage; folding wings were planned for the SF-36.
Engine is an 80hp Limbach SL2000 driving a fixed-pitch or a three-position variable-pitch airscrew. Construction is of glassfibre-reinforced plastic, and a two mainwheel undercarriage similar to that of the C-Falke '80 is featured, although a single monowheel with small outrigger wheels under the wings was also offered to customers. The latter was featured on the prototype, which first flew in the summer of 1980, and a retractable single-wheel undercarriage was planned for a later version; in all cases the tailwheel is steerable. The forward-sliding canopy allows entry to be made over the wings.
First SF-36 deliveries were due to start in the spring of 1981. The SF-36 R two-seat motorglider was expected to go into production in France.
