Barry, 23.05.2016 16:22 The Lippisch Delta IVb was a follow on of earlier Lippisch designed deltas. The original IV was ordered by Gerhard Fiesler for an aircraft that he could enter in the 1932 "Europarundflug" rally. Lippisch supplied the plans and Fiesler built it as the F-3 "Wespe" (Wasp). It proved very unstable and Fiesler crashed it on it's first flight. Lippisch was undetered by this development and found an ally in Walter Georgii of D.F.S. Georgii got funding from the RLM and the IV was purchased back. Lippish moved the engine to the front altered the wing design and at last had something quite worthy. Then in 1936 the final design changes were made an the Delta IVb was taken to Rechlin where it was flown by Heini Dittmar and was awarded its C of A and was given it's official name DFS 39. Later it was used as the basis for the Me163 rocket fighter. Power plant 1 x 75 h.p.
