While not a fully-adopted-for FSX, here's a model designed for FS9 that's been ported over to FSX: The venerable F-86 Sabre from SectionF8.com.
The Sabre has always been one of my favorite fighters and even today it still has gorgeous lines.
It's interesting that while the F-16 is known as having the worlds best near-360-degree view, the F-86 had a gorgeous bubble canopy, not unlike it's prop-driven predecessor the P-51 Mustang.
Not sure when SectionF8 will release a fully compatible FSX version, but this one flies just great as is - and damned if it doesn't look nearly real in the air.
Here's a few screenshots from a recent "flight". Enjoy.
