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 (102 of 115 built) were Twin III Acro models, with G-Limits of +6/-4g. However, aerobatic maneuvers were limited in 2003 by an airworthiness directive[1] and could only be reinstated with fuselage reinforcements.[2]
