I have the wing gun ends to make and add and the Perspex wrapping to remove and then I shall add the r2d2 head for the finished look.i will later sometime have to purchase an r2 head from somewhere to sit permanently on the X wing though.i don't have the machinery or knowledge to make my own r2 head yet I've not got a vacuum machine or a 3D printer I'm more old school all done by hand with day to day materials .saying that I could probably find some domed shaped item some place and add the paint job myself if I could find something suitable!
It's definitely getting there,but I sincerely hope you won't leave the back of the plane like this though; if you look at any x wing model,you'll see that even the back has details
