RE: 4 Star 60 Two piece Wing Conversion
Unless you travel by bicycle, why would you want to go to all that trouble to make an inferior product? A friend built a Dynaflite PT-19 with a two-piece wing, for space problems, and he did it with an aluminum-tube joiner. This requires a carbon-fiber or aluminum tube in each wing half. After all that work, he bought a van.
Compared to the one-piece wing, it is a lot of work.
