KR2S Wings under construction. I
used the standard RAF 48 airfoil and
used the washout and wing incident per
the plans. These are scratch built using
Styrofoam. I do not plan to put any
fuel in the wings.

Top right wing,
the wing is
already glassed
from the forward
spar back. The
foam is microed
in place forward
of the main spar.
I then used an 8'
long 2"x2"
aluminum angle
with 80 grit sand
paper as my
sanding device.

Wing tips are just 3
layers of 2" Styrofoam
for a total of 6 inches
extension of each wing.
I didn't get too
elaborate with the tip,
just sanding the edges
to a get a round
aerodynamic structure.
