IMHO, Vacuum bagging would be the way to go.
You can cut and prep the cores one day and bag the second day. There is
probably as much work in a foam wing as there is in a built up wing, but it
should come out more accurately (accurately is said with some trepidation, see
UICU results on airfoil testing). You don’t need to paint the mylar,
just wax them and they are ready to bag. Color if desired can be handled
with colored cloth.

Wing Building Techniques: Foam Laminated vs Built up Pro's and Cons?
Gang,
I know the usual answer is "it depends" but which is the better build
method?
Here are the considerations...
1. Time (I want to build as quick as possible)
2. Accuracy of the build. I can cut foam wings and I can cut ribs
by hand. I can also outsource these functions to have the performed by
computers.
3. Durability. Which will generally take longer to wear out?
4. Easy of building. I have the bags, pumps, epoxy, ca, balsa
etc... to build either.
5. Prototype? Which is the prefered method to prototype
ships. This would mean really quick, almost disposeable building so that
a basic feel of the plane can be gained. I can see covering a foam wing
with tape or building a ribbed wing with fewer ribs and full balsa sheeting.
6. Any other considerations you may have.
This will be my first official building season, and I plan on building several
60 inch planes from DLG, to mini hotliners. I purposely didn't ask about
spars as I think the same spar can be used in either construction method.
Thanks.
Jay
