To increase climbing speed a Do C 2a was fitted
with an additional smaller wing, becoming a sesqui-plane. First flown
on September 18, 1931 from the Bodensee (a large lake at the
borderline of Germany and Switzerland) the conversion was not
generating the foreseen improvement and it was not put into
production. The three-seat Do 3 was the direct predecessor to the Do
22 used in Finland and Yugoslavia.
