<DIV><FONT face=Arial size=2>Whether it's worth it or not totally depends on the
amount of weight you're looking for. Actually cutting the honeycomb isn't too
difficult or time consuming, but making the templates can be a little
painstaking. However once you have them, you have them for a few
planes.</FONT></DIV>

<DIV><FONT face=Arial size=2>I am currently running a fairly thick tip section,
and performed honeycombing on the outer half of the wing panel past the spars.
It saved about an ounce per panel compared to the first set I made. So, you save
a couple of ounces, and remove some mass from your wingtips. Does it help? I'm
sure it doesn't hurt, and theoretically (being the operative word) it can help
in dampening snaps and spins...but not a lot, unless your tips are really heavy
to begin with. </FONT></DIV>

<DIV><FONT face=Arial size=2>If you're building an electric or a plane that
historically comes out close to the limit, it could be worth the effort. I'm not
sure it's worth it on a 10 lb or less plane.</FONT></DIV>

<DIV><FONT face=Arial size=2>Just my 2 cents.</FONT></DIV>

face=sans-serif size=2>Does anyone happen to have some experience in weight
reductions from foam honey-combing? Wing cores, stab cores, vertical fin
