Default RE: Foam Core Wings. Light, or heavy?
you don't need to fully sheet a foam wing. You can just sheet the LE and TE and then add cap strips
Well it is not quite that simple, unless I missed something. With the cap strips in place the bays between them will have to be cut out or recessed about 1/4" deep both sides of the wing. If they are to be cut out completely the top and bottom cap strips will have to line up.

Why do the bays have to be removed you ask? If the foam is not removed, when the covering is applied it will sag between the cap strips and stick to the foam. The result will be one awful looking wing with sort of flattish patches in every bay and a truly wierd airfoil. It will be a mess.
