Began modifying the 3D model for the latest variant a couple days ago:
Creating a more pronounced dorsal hump to extend to the modified vertical stabilizer.
Very little of the canopy had to be modified to make it appear correct for now. Still working on the dorsal hump and correcting some minor issues with the topography of the mesh. Lots of changes that look deceptively minor, but actually take time to do.
You can see there's a bit of a "ridge" near the base of the dorsal hump which was the result of moving things around while shaping the hump. That'll be corrected, possibly by welding verticies together or just moving them. Also have sort of a flat spot to take out of the fuselage. The intake will also have to be modified a bit. The pitot tube needs to be re-extruded on the starboard side of the intake, and a few of the bulges along the fuselage and stabilizers have to be modified. Much work for this weekend...
Cheers!
