foam core question

[Mark Hunt]

Sirs:

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....?

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.

Thanks in advance for the help...
