Development
The S.I was designed by
parasol wing with two side-by side seats for instructor and pupil in a wide cockpit. It first flew in early 1919 at Schwerin. Although the prototype performed well, the unusual cantilever parasol wing was not liked[citation needed
] and only three production aircraft were built.
Two production aircraft were powered by 60 kW (80 hp)

engine and was designated the TW-4 (Trainer Water-cooled).
