On all of the other kits in the 500 series of low wing warbirds the wing formers and the fuselage mate somewhat closely (nothing that sandpaper wont fix) however the wings on the Zero/Ruffe do not match at all.
How exactly do you manage to attach them?
I mean on most of these a thing bead of glue on the centerline and central wing rib and a little dab on the F2 ribs and the fuselage side formers and you can get somewhat of a good fit. The Zero/Ruffe just doesnt seem to work well.
