Eric, you know I disagree that these are huge expenses. I continue to

I disagree. IMHO, sailplane development is an extremely complex task
far out of reach of anybody without some very sound aeronautical
engineering education. And not only that, it also requires a good deal
of experience---read: your first design will not necessarily be the best
one. :-)

That said, I'm open to be proven wrong by counter-examples. Anybody
knows any?
