It all depends on which material you are comfortable with; foam or balsa. I’ve been comfortable with balsa. I’m now experimenting with cutting foam wings and building with foam.
As Appowner stated, a balsa wing is not hard to build. Here is a picture of what he states. My plan is just drawn lines on freezer paper. Shaped wing ribs and rib spacing. Tapered wings are best built in a jig, IMO. Even the jig is not hard to make. You just need to give it a try. The sooner you start the sooner you finish; balsa or foam.
