That's the Captain Sim X-Load model. The only "problem" with the pack is that it uses the Accel F/A-18A's VC in both the -18D and the F-117. I never fly the F-117, so that doesn't bother me. I love the twin-seat Hornet.
Unfortunately, there is, as you suggest, ColoKent, no loaded single-seat F/A-18 currently available. There is another one in development for FS9, which will supposedly be remodelled to FSX when complete, but I learned a long time ago never to believe something will happen until I actually see it! :d
