I have this kit on the bench right now but it's an older kit I bought at auction. The wing is built in two pieces and joined together. Unless it's something new, and that can happen, then it's still A one piece wing. CG does make changes but it isn't very often. It's one very well made kit but the cowl and landing gear leaves something left to be desired, wheel pants too. I got the replacements from Fiberglass specialties, more bucks but worth it in the long run.
