It looks like you have a Jet Hangar/Violett A-4. They have one-piece wings. The Yellow kits have foam wings that join the fuselage in butt joints at the wing root. The old Yellow version had wings that glued permanently to the fuse and I believe the new ones are detachable at the wing root via aluminum blade spars.
I fly an older Yellow A-4 with scale wings on OS 77/Dynamax. It flys great!
Good luck with it!
