There are several European builders who use both a molded skin AND a foam core. They are NOT mutually exclusive. I believe Fiberglassfluegel may have pioneered the technique with their ASW 20 in 1985. The skins are molded as usual, but left in the molds. A layer of epoxy is applied on the inner surface of the skins, a slightly oversize cut core is placed between the skins and the two halves of the mold joined with vacuum inside the mold to suck the epoxy into the foam and pressure on the outside to compress the foam to size. This makes for a very tough wing, although sometimes more difficult to repair than the standard 'molded' wing. The French builder Aeromod and at least one Russian builder currently use this method as I have a plane from both that have this style of wing construction. As Mike Lachowski noted, it is also possible to have the skins separate from the 'filler' of a molded skin, requiring you to glue it back into position.

When asking the best way to fix it, Martin Doney passed on a tip he had learned. It's a small thing but it really works great. He said to take a tee pin and bend the tip 90 degrees about 1/8 inch from the end. Poke a hole to drip in some CA. After the CA wicks in, just rotate the pin and use it like a hook to lift up the foam to the skin while the CA cures. RCSE-List facilities provided by Model Airplane News.
