It's true. All the high performance sailplanes do it. In fact, if you look
at an accurate Europa profile you will see that the flaps should be
reflexed very slightly. Walter Binder, (doesn't speak English much) did it
many years ago on his much modified Classic with good results. The used to
tow gliders with that particular Europa I'm told. Not with water ballast in
I trust!
