I put together a rough fuselage just to see what could be done
with the 1.5mm foam. I started out with two balsa sticks and then
glued the formers to them. Then I cut the body panels to shape
and scored them heavily with an x-acto on the outside. The
panels where then shaped around a steel rod to bust them into
the concave shape and then glued.
The scoring looks like aluminum sheet metal so I first gave the fuse
a black wash and then dry brushed over that with acrylic silver.
From start to finish about an hour and a half- the same thing done
in s&t would have taken me 10 times as long just to save maybe a
half gram.
The finished fuse weighs 3.6 grams.

micro, you could probably build a channel wing with this stuff, trouble is,
where would you begin?
