Graham,
Thanks for your response, I certainly agree that the Europa concept "seems to
work" as you put it. With all the lay-ups and required filling and sanding of
a
"Rutan Wing" it seems to be a valid question if a premolded wing might become an
option (super fast kit?) for the future. Many potential builders - I for sure
-
would be happy to consider it.
As you well know, all the recent successful American glass kits are offering
wings made in molds.
