Dear Stealth,

I agree. Steve's strut-braced wing is a wonderful example of
engineering, worthy of study by anyone having an interest in the
practical side of aeronautics. But the same can be said for Ken
Rand's wing or the geodesic wing of Bert Sisler (indeed, the wngs of
the 'Cygnet' and the 'Tailwind' are sisters under the skin).

But not for a Primary Glider :-)
