If one were to build something like a simple sweept flying wing like the Silence from Hartmut Siegmann (https://aerodesign.de/modelle/HS/hs29.htm) today, would you copy+paste og do it differently?
it's a HS 3,0/8,0 as written at the 3D-View upon, -3 degree washout, also to be seen at the picture above.Nice.
Which airfoil??
