Wings are huge, so they are split up into two parts. (Wingspan is about 14 inches long but it is split into two 7 inch parts so it should be fine) Body and stabilizers should be one part. Wings and stabilizers are pretty thin. (2 mm thickness) Wings are designed so they can just be glued together and then glued on top of the glider.
