New Scale DC-3
I am starting to build a scale DC-3. I want to build the wing with foam. I have used foam wings in the past on scale planes and it looks great and is strong. I have just never tried it with a 100+ inch wing. will it be too heavy? The longest I have ever gone is 60" on a foam wing.... Any input would help...

New Scale DC-3
They can be done in foam, on this type of wing however, you would have to cut them into two pieces, and after sheeting them they would be glued together (or bolted).
The advantage that a built up wing has on an airplane such as the DC 3, is that there is a whole lot of stuff that has to be inside the wing center sections, such as nacelles, fuel tanks, engine servos, retracts, plumbing, flaps, actuators, pushrods, etc. and all this is so much easier to install on a built up wing, I have done other twins with foam wings, but a lot of foam carving goes on, and the wing has to be strengthened by adding spars.
My suggestion is to go with the built up center section, and then the tips (from the nacelles outward) done in foam.
On an airplane like the DC 3 you'd probably be better off building the entire wings center section as one piece, right up to the nacelles, the outer sections can be done removable, it would make transportation so much easier.
