The Akaflieg Stuttgart FS-24 "Phönix" ("Phoenix"dn) was the first glider to use fibreglass in its construction.

The design was started at the Akademische Fliegergruppe Stuttgart by R. Eppler and H. Näglele in 1951. Originally it was constructed of balsa wood with a strengthened outer layer of paper and glue layers. The project was abandoned until a grant was received for further research. By then glass fibre reinforced polyester resin was available and so it was redesigned using a balsa wood/glass fibre 'sandwich'. The load-bearing points and the edge of the cockpit canopy were strengthened with plywood. It made its first flight on 27 November 1957.

For its first flights it had a conventional tail unit but later a T-tail was added. The landing gear was retractable. Eight Phönixes were built.
