Ho Vc: Rebuild And Distrust
The official verdict of the Gottingen tests were not flattering. Professor A. W. Quick from the Aircraft Testing Department in Berlin stated that "maximum lift decreases with increased sweepback, which also causes pitch instability, stall danger and difficult steering"! The H V c had proven all this wrong during its test program, but the results were unfortunately never published.
Previous wind tunnel tests of a flying wing model in Gottingen, were probably the reason for its reluctant acceptance. The swept wing tested was quite different from ours, with the wrong aspect ratio, wrong taper, wrong washout and different control surfaces. The data obtained from this model was correct, but had little to do with our design.
The end of the H V c came in the spring of 1943, during a takeoff. The aircraft failed to gain altitude, and hit the roof of a hangar. The pilot was not hurt. It appeared that he had attempted to take off with the flaps in the full down landing position!
