fuselage, or much the same fuselage, had been used on most of his gliders, the only change being to the wings." He also noted that the wings were built professionally. An accompanying, undated photograph shows the glider with a further modified, rounded rudder. Operational history Towed trials were begun in the late Spring of 1932 but encountered lateral instability problems. An increase in rudder area was not the answer but it seems a cure was found, perhaps by completing the cockpit enclosure, as a particular flight was noted on 13 August 1932. The early tests were made from the London Gliding Club's Totternhoe field on Dunstable Downs. By 1938 it was flying at Duxford. Its final flights were made near Worcester, Nyborg's home town, in the late 1950s. Despite the long flying life of the T.G.N., no careful assessment of its performance seems to have been made to decide between the predictions made by the designer, his contemporary critics and later analysis. The Nyborg T.G.N.III survived in store at Warwick in the early 1990s, number 25 on the British Aviation Preservation Council register.
