<DIV>Carbon Fiber mat or veil, in substantial weight rating, will absorb a great
deal of glue. The only reasonable way to do a carbon veiled wing is as Jerry
suggests, to roll out practically all the glue and vacuum bag it. </DIV>
<DIV> </DIV>
<DIV>Be that as it may, in my experience it is an unecessary weight addition.
Sure it adds stiffness but for what purpose? These models are not jets or racers
that need to be strong at 200+mph. A little more flexibility in the wing is
not a bad thing for pattern models. The trick is knowing when the nice
balance in properties has been reached. </DIV>

<DIV><FONT face=Arial size=2>Sounds good to me. There are a lot of ways that
work well.</FONT></DIV>
<DIV><FONT face=Arial size=2>BTW, some of the drywall mesh is made with very
short fibers: if you can tear it easily, don't use it.</FONT></DIV>

<DIV><FONT face=Arial size=2>John, we put 0.5 oz carbon mat between the
foam and sheeting, same amount of slow epoxy ( really thin rolled on to
the mat ), with a little brushed around the edges of the
foam, and bag them. Gives an incredibly strong wing,almost
monocaque, with little added weight. Also add a small piece at fuse
end TE to prevent the "pick up bends" .</FONT></DIV>
