Mark, I think you would be hard pressed to even break even selling a built plane. It costs too much, and most people are not willing to fork out what it would cost just to cover the expense of the parts you put into a plane. I have sold a couple really nice kit-built planes in great condition when I no longer enjoyed the models, and maybe recooped 1/2 to 3/4 of my investment, and that's not taking into consideration the time spent on the assembly. That's why ARFs are so popular now. Add to that the cost of shipping, and it makes it impracticle to sell a built plane for profit. Most people looking at an assembled kit-built plane question the workmanship of an unknown builder as well.
