The Jantar 2 sailplane, has elastic camber changing flaps, which spreads the
hinge-point over a longer aria of the cord , of the upper skin ; does anyone know
what composite materials were used for that ? I'd think fiberglass would be
too brittle for that job , and who made a flexible epoxy, back then ; or was
that hinge , made of a rubber type substance ?

I believe another sailplane , did the same type flex-skin for it's ailerons ; can't
remember what glider though ? I bet the stick pressure, was kinda high, on it.
