the zero is a very nice plane. they do come from the same manufacturer that GSP carries and i happen to have one of these models. I am a distributor of these planes in my country in the Philippines. The fuselage is fiberglass with panel lines molded on to it. the wings if i'm not mistaken are built up and are covered with solartex. the regular green scheme is airbrushed on to the wings, tail feathers, and the fuselage. the fixed landing gear also has a plaStic fairing replicating the scale landing gear. a very nice plane if you ask me. I also happen to carry the EZ arfs from japan and i don't think the EZ Zeros even come close as to the scale qualities. I guess the only thing lacking with this kit is weathering but i guess that would be easy fix anyone could patch up.
here are some snaps i took of the fuselage
