Hmmm....

I was wondering if metal gliders have an L/D disadvantage
due to the metal, or because of the lousy rivets and
poor wing airfoil and draggy struts (of the SGS gliders,
for example).

Is it possible to make a retract gear metal glider with
flush rivets and a carry-through spar which would give
40:1 ratio, or is metal just a substance that won't
allow the shapes or fine tolerances needed to make such
a wing?

Vans seems to do an excellent job selling very high
quality kits with very nice wings (metal). I wonder
if they'd consider selling a Quickbuild glider kit?
