<DIV><FONT face=Arial size=2> Hi Jim I have a friend in NY, Scott Miller no
longer flying pattern but in his time he, "weight freak", built a set of wings
for the "Omen", George Asteris design, with retracts and servo at 12oz. a panel.
I'm not 100% sure but I know he used .070 or 3/32 4-6oz. balsa weighed and
picked the 20 lighter sheets out of bundle of 50 matched weights for the Lt
and Rt panels, honey comb the foam cores then transferred the out lines to the
prepared skins and like Ron said only applied glue where required to bond with
the foam. Sounds like a lot of work to me and don't know how strong or how long
will it last but take the retracts, wheels, retract plate and false rib and that
will be a hell of a light weight wing panel.</FONT></DIV>

<BLOCKQUOTE><?fontfamily><?param Arial><?smaller>My last set of wings I
cored out around the fat part of the wing between leading edge and wing tube
and behind the wing tube and saved .5 oz per core. Some of the
guys that honeycomb the whole wing are saving about 1 to 1.25 oz per
panel. But they generally glass the wing and paint it
too. I hollow out the wing tips then cap them with 1/8 lt balsa
wood and lighten the root rib also. Overall this way I save about 1.25
per wing panel from the regular
way. <?/smaller><?/fontfamily><BR></BLOCKQUOTE><BR>I wonder how
much adhesive weight is also saved, because the skin adheres to less foam. I
guess it depends on whether you put the adhesive on the foam or the
skin.<BR><BR>Ron Van Putte<BR><BR>

RE: Foam Honey-Coming Weight savings<?/x-tad-bigger><?/fontfamily><BR><BR><?fontfamily><?param Arial><?color><?param 0000,0000,8080><?x-tad-bigger>Well…I
can’t speak for the current wing plan forms, but we did a bunch of tests
on the older Arch Nemesis wings and at the time…it was a waste of time.
Granted…we weren’t quite as close to the weight limit then… but all
in all we saved on average less than 1oz per panel in the finished
product…about 1.75oz TOTAL in the plane. Not bad if it was
quicker to do, but at the time it was a lot of work for very little gain.<?/x-tad-bigger><?/color><?/fontfamily><BR><?fontfamily><?param Arial><?color><?param 0000,0000,8080><?x-tad-bigger> <?/x-tad-bigger><?/color><?/fontfamily><BR><?fontfamily><?param Arial><?color><?param 0000,0000,8080><?x-tad-bigger>Now
