gopp-go-3

 

In 1938 the company moved to Kirchheim/Teck and employed more than 300 people during the war time.
 
The first serial gliders were the aerobatic single seat trainer GÖ-1 'Wolf' from Wolf Hirth and the renown GÖ-3 'Minimoa' as well as the two seat GÖ-4 from Wolfgang Hütter.
 
One of Germany's leading high performance single seaters before the war, this gull-winged glider was designed by two of Germany's leading sailplane pilots, Martin Schempp and Wolf Hirth. They designed and developed the Minimoa from the 20m span Moazagotl, and the name Minimoa is a contraction of miniature Moazagotl, although the design was also known as the Goppingen 3.
 
In its original form it had cantilever shoulder-mounted gull wings, and it was built by Wolf Hirth and Dipl-lng Wolfgang Mutter. Of conventional wood and fabric construction, the Minimoa is characterised by swept back wing outer panel leading edges and large ailerons with trailing edges projecting beyond those of the wing itself; air brakes of the same basic Schempp-Hirth type later to be featured on many other sailplanes are fitted. The tailplane is mounted ahead of the fin and is raised above the fuselage top line. The pilot sits under a one-piece hinged cockpit canopy that opens to starboard, and by prewar standards the cockpit was roomy. Landing gear consists of a non-retractable monowheel and a skid under the nose, plus a small tailskid. By 1938 the Minimoa 3B was introduced with the gull wings now in the mid position with a modified aerofoil section, and reduced weight. From July 1935 to 1939 a total of 110 Minimoas were built, of which 13 were sold abroad to Britain, France, the USA, Argentina, South Africa and Japan; a few survived the war and are still flying.
 
First flown in 1935, the Minimoa made its mark in contest flying, taking third place at the 1937 International Competition at the Wasserkuppe in Germany flown by Wolfgang Spate. Richard du Pont and Chet Decker flew Minimoas to win the U.S. Championships in 1937 and 1939.The Minimoa established a number of records, including the world altitude record in 1938 (using lift in cumulo nimbus cloud) of 6,687 m/ 21,939 ft. The name was an abbreviation of its original nickname, Mini- Moazagotl, as it was a smaller successor of Hirth’s earlier 20 m. Moazagotl.
 
Distinctive in many respects, the Minimoa was stable, but with poor roll control by later standards. It was the first sailplane to carry water ballast, in a tank behind the cockpit. Structure: wood/ fabric wings and tail, wood fuselage.
