Not the same wing contruction Jack. This is the old mold less
construction invented
by Burt Rutan. Glass over hot wire cut solid foam cores. As anybody that
has built a LongEZ can tell you there are hundreds of not thousands
of hours of sanding needed. Here is a screen capture from their web site.
Another draw back is it is heavier as it is hard to control the
resin content when glassing the foam. Also the wing is solid foam
so anything, such as wing tanks or landing gear, placed inside needs
extra work to hollow out the solid foam core.

Paul, Ken Rand did mold less construction BEFORE Burt Rutan, Virg


I did that before Ken Rand did it in 1972 :) I did mold less styrofoam
and epoxy antenna mast in the early 1960's while working
for Melpar.

Rutan made it famous.
