Design and development

The RF7 was a conventional motorglider design derived from Fournier's RF 4D,[1] a low-wing cantilever monoplane with an engine mounted in tractor configuration in the nose.[2] The sailplane-style undercarriage consisted of a retractable mainwheel, a fixed tailwheel, and small outriggers under each wing.[1] Compared to the RF 4. the wings were shorter and the tailplane surfaces larger.[1][2] The ailerons were also larger,[3] and the RF7 was fully stressed for aerobatics.[3][4]

Construction of the prototype (registered F-WPXV[3]) began in July 1969,[1] and the aircraft first flew on 5 March 1970.[1] It was displayed at the Hanover Air Show the following month, where the journal Flight International praised it for the quality of its finish "[i]n spite of its prototype status."[3] By 1971, Sportavia-Pützer abandoned its plans of series production of the type and hoped to market the RF7 in kit form instead.[4] By 1978, all development had been abandoned and the prototype was offered for sale.[5]
