I thought I'd start assembline my Parkzone Spitfire today, when I get to put the wings on, the screws go through fine, but they don't seem to go through anything else, the wing dosen't stay on! The screws go through the wing OK, I see the holes they are meant to go in, but it won't stay on! I'm not sure if they are connected properly or what, the instructions are clear, but do not explain as much as I'd like it to.

Anyone else with experience on this?

I had the same problem. The wing looks aligned okay, but it isn't and you're missing the holes. Try using a flashlight to look through the hole, line it up, and insert the screw. Once you have one in securely, the others are easier to find.
