That is what has been used in the construction of my KR2, for both the
tail feathers and the wings leading edge. Although I could not tell which
density was used And so far so good.

Objet : KR> Expanded polystyrene foam
I am contemplating the use of white EPS for tail feather construction.
A KRnet search revealed no entries related to expanded polystyrene foam
for use
in KR construction. I found several entries on extruded polystyrene foam
colored
blue, pink or green in 2lb density. Has anyone used the 1lb white foam?
This
is the stuff commonly used for concrete displacement blocks in house
foundation
walls to block out window openings and brick ledges. This stuff is very
light,
cuts great with a hot wire and bonds well with epoxy. I have used it in
the
construction of large scale RC aircraft wings with excellent results when
covered with .75oz bid glass and epoxy. Hot wire cutting requires only
light
sanding with 220grit to remove the hairs and requires no micro filler.
