That is a good looking Harrier you built, Tosh.
I saw one at a Confederate Air Force air show in Harlingen, Texas (very near the border with Mexico) back in about 1976. Maybe 1978, who knows, the memory is not as good as it once was. I do remember thinking it was like something out of a science fiction movie, taking off and landing vertically as it does. And it was so very loud!
As to the Academy P-38, I recently built that kit as the F-5 Lightning, the photo recon version. It is a really good kit with decent details. Your Eduard set will really spice up that bird. Look out for the wing to boom connections, and the booms can actually twist out of alignment to where the rudders are not properly vertical.
