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.

[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.
