<DIV><FONT face=Arial size=2>As a newbie to cutting foam cores, I have a
question regarding how to strengthen the wing panel. Does the preferred
method include attaching some c.f. strips to the inside of the skins?
Should they extend from the root all the way to the tip? I know some
guys feel it is a must to also use a false rib near the end of the tube sleeve
also? I hear that some guys (r u out there Nat?) are confident without
any false rib or c.f. under the skin....?</FONT></DIV>

<DIV><FONT face=Arial size=2>I cut the cores earlier tonight (to rebuild my 2M
after a mid-air) with the help of a friend, and they turned out just
beautiful. I have a nice plan to machine a drill jig for cutting the
spar tube hole...so that's seems to be solved.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks in advance for the
help...<BR></FONT></DIV>
