A Flybaby would be the perfect plane to try to cut yourself. The fuse and tail are mostly sticks, and the wing it is straight, ie no taper, right? Many of the ribs will be similar. Cut a few plywood parts for the load bearing fuse structures, and you will have a kit. A scroll saw is all you need really. Cut the part oversize, and sand to the line. If you have many holes to drill, especially lightening holes in the balsa, buy a forstner type bit as they make really nice holes in balsa.
Mr. Crump is correct in saying that is satisfying to do it all yourself. When you are done, you will want to punch the first guy that asks "Which ARF is this?"
