DFS Weihe

The Weihe 50 is a classic glider with it's own unique charme. Accidentally we got a construction manual of the Weihe 50 by Graupner, with a wingspan of 1,80 metres. The small model was quickly copied – and we liked it!
So it was clear that this would be our next glider model! Therefore only the question of the suitable scale had to be clarified. We decided to build on scale 1 : 5,5, corresponding to a wingspan of 3,27 metres

Based on the image of a original drawing from internet, all CAD-drawings have been created. A special challenge was the wing connection which, unlike the original, does not allow the wings to collide in the middle. At this point there should be an easier to build construction. The appropriate fuselage formers have been widened horizontally, so they extend beyond the width of the fuselage. They got pins, which fit exactly in the root ribs of the wings. With this the exactly position ist fixed.

Especially gratifying was the weight of the prototype after completion. It weighs only 2850 grams including built-in RC-system! It's also very pleasant that the Weihe can be assembled in short time. The wing attachment with rubber bands used by us (see picture gallery) keeps together very good!

Since it didn' t work with the slope winds for the maiden flight, we soon embeded an additional tow release. On 7th April 2012 it finally happened - the maiden flight could take place.


History

The Weihe of Hans Jacobs was probably one of the most successful glider models with high performance. The prototype was developed in 1938. Hans Jacobs learned gliding construction from Alexander Lippisch, who built many models in the 1920s, such as the Fafnir and Fafnir 2. The development of the DSF Weihe started in 1938 and finally ended in 1959.
The fuselage of this glider was built in half-shell construction and planked with birch plywood. The Weihe 50 of Fokker-Wulf was created after the war years of 1951, after the prohibition for the construction of German gliders has been lifted. As the construction of the consecration was very expensive, production was discontinued in 1958. Until then the Weihe had received an improved wing surface, changes in the front fuselage part and a beautiful blown canopye.
