The DFS Rhönsperber, known as the Schweyer Rhönsperber or Jacobs Rhönsperber (in English Rhön Sparrowhawk), was a single-seat glider designed in Germany by Hans Jacobs. It was first flown in 1935. For several years it was regarded as the best German glider, with about one hundred being built. The Rhönsperber glider plan is 1/5-scale size. It is designed after a single-place full-scale glider. The model has a wingspan of 120 inches when built. It employs built-up balsa, plywood and spruce construction, with miscellaneous hardware required.
