Here is an idea I found in the kit building thread. Check Post # 39 and on:

That foam construction is pretty slick! Years ago I built a 1/2A wing and made the ribs from egg carton foam. Worked out great!
As mentioned previously, one way to cut back on balsa use would be to go with glass fuses and foam flying surfaces. The foam could be covered with 1/64" plywood skins instead of balsa and would only be slightly more expensive than contest balsa. Obeche would also be an option.
The lost foam method could be use for wing and stab tips. Carve the tips, glass them and remove the foam. A simple process that doesn't require making any complex molds.
Just my $.02!
I guess the ARF guys will never have to worry about this situation!
