Grob G103c Twin III
The G103C Twin III is a high performance tandem two-seat sailplane made by Grob Aircraft. It replaced the Twin II in production and features a new triple-trapezoidal wing, automatic elevator connection, lower control forces and higher airspeed limitations.
Most Twin IIIs were Twin III Acro models, with G-Limits of +6/-4g. However, aerobatic maneuvers were limited in 2003 by an airworthiness directive and could only be reinstated with fuselage reinforcements.
