So far I have a rough body with the nose complete, a rough placement of the cockpit and the undercarriage complete. I'm using the Jedi starfighter for parts so that's the canopy I have gone for and although I don't have the newest x-wing I have peeked at the instructions for some help on the nose.
Due to the way the wings are (3 levels on each side and 3 on top, 1 in the middle and 3 on the bottom) the body has been dictated by where I need to place hinges.
Here's the top set of wings so far with the back one still a WIP.
