Pfenninger Elfe

The Elfe series started from a 9 m sailplane designed by W.Pfenninger before World War II. A new design was introduced by him in 1947 to become the Elfe 2, probably the first sailplane with a laminar flow airfoil. Subsequently the series was further developed by Markwalder to become the Elfe PM-3 (brought to the US in the sixties), then by Albert Neukom the Elfe M, Elfe MN and AN66 before the Standard Elfe S-1
