Grob is
a company well known for sailplanes and powered
gliders. It produced the G 110 in the early 1980s,
and the G 112 in prototype form only; from these
developed the G 115, whose prototype first flew in
November 1985.
The prototype entered production as the G 115,
constructed of glass fibre reinforced plastics. A
second prototype with relocated tailplane and a
taller fin and rudder became the G 115A. they
remained in production until 1990.
Production recommenced in 1992 with improved
models designated G 115 B to D, with further
sub-variants. These were powered by engines up to
180 hp (135 kW), with other changes such as fuel
in the wings, or variations to cabin glazing. A G
115TA Acro was also produced, with a 260 hp (195
kW) engine.
