Superhansa
During my research for the He 8 (H.M.II) I took a look at the Swedish He 5, the succes of which made the danish navy choose the He 8. 57 of these served as S 5 in the swedish air force (Flygvapnet) from 1927 til 1945. One even managed to shot down af Heinkel He 111 in april 1940.
In 1931 Svenska Aero AB proposed an improved version known as S 8 Superhansa. It had the same layout but a stronger engine and some aerodynamic improvements. As the performance would only be slightly better than that of the S 5, the project were abandoned in 1933.
But what if!
The only illustration I have found is a picture of a windtunnel model. But comparing it to a picture of the S 5 shows a remarkable likeness. And as I do known the dimensions of the S 8 Superhansa a model should be possible.
And as the Frog Vickers Vimy, that I have used for the H.M.II, is a bi-plane, I do have some wings as starting point. My private scrapyard delivered some other items, that might be usefull.
So let the work begin.
