Great! Glad you got 'er flyin!
Now, two things to think of: I don't have the D model, but I suspect the weight-n-balance section of it's aircraft.cfg is probably pretty inaccurate. I might well be mistaken, buuut...
Take a look at the equivalent loadout in the v16.1, and see what it's weight-n-balance section looks like. Not just the station entries, although they matter a great deal, but the 3 MOI's as well. I know the D Model is heavier, so the MOI's will be slightly higher, and you will need to add at least 1 Station to account for the GIB, if he's in there. Remember that, say, a wing hardpoint will have 2 Statioon entries, one for the pylon, and one for the missile(s), bomb(s), or whatever is mounted there-on.
Second, if it doesn't fly "right" you can adjust the numbers in the Hornet_FCS section, but if you do, be VERY cautious. The numbers are for the FCS PID controllers, and a small change can have very large effects. PID controllers are a real adventure. Look them up on Wiki. There's a great article about them. Just FYI, btw, the AP settings include PID controller numbers as well. Adjusting them can really throw things off, so if you're going to make a change, change only 1 number, and only change it a very small amount. Not just numerically, but percentage wise. Then test thoroughly. VERY thoroughly. Then and only then go on to change it more, or another number, or whatever.
If it flies like you like, though, leave it alone
