Development
The first model had an all-flying tailplane, with anti-balance tabs along the entire trailing edges, and a two-piece canopy (movable and fixed parts), built of GFRP (glass-reinforced fibreglass plastic)/foam sandwich materials and resin impregnated rovings for high strength parts. Successive developments included the DG-100G, DG-101 and DG-101G. Most models are available with water ballast bags in the wings.
The DG-101 and DG-101G had improvements such as a single-piece front-hinged canopy, improved crash resistant cockpit and a conventional tailplane (with fixed horizontal stabilizer and articulated elevator). There was also a club version of this sailplane with fixed landing gear. All models featured top-surface-only air brakes.
Some later models were also manufactured by the Elan company in Slovenia and can be identified by the word "ELAN" on the fuselage and rudder. The serial number of these gliders is prefixed with "E".
Although these gliders were designed in the 1970s, they are still popular in the Club class and remain competitive in Sports class contests (which are handicapped).
The wing's control surface hookups are non-automatic and utilize L'Hotellier fittings, which must be secured by a secondary means such as a safety pin, safety wire, Uerling Sleeve or Wedekind Sleeve (See this web page for more details on this subject).
The Glaser-Dirks Company declared bankruptcy, after which the newly-organized company DG Flugzeugbau GmbH assumed responsibility for servicing the gliders.

Famous quotes containing the word development:
“There are two things which cannot be attacked in front: ignorance and narrow-mindedness. They can only be shaken by the simple development of the contrary qualities. They will not bear discussion.”
—John Emerich Edward Dalberg, 1st Baron Acton (1834–1902)
“I do seriously believe that if we can measure among the States the benefits resulting from the preservation of the Union, the rebellious States have the larger share. It destroyed an institution that was their destruction. It opened the way for a commercial life that, if they will only embrace it and face the light, means to them a development that shall rival the best attainments of the greatest of our States.”
—Benjamin Harrison (1833–1901)
“The young women, what can they not learn, what can they not achieve, with Columbia University annex thrown open to them? In this great outlook for women’s broader intellectual development I see the great sunburst of the future.”
—M. E. W. Sherwood (1826–1903)
