I have two separate questions and I don't know if they're bugs or not.
First, as far as I can tell, you can't command full stabilator deflection, either forward or aft, with a centered trim position. I figured if I was dogfighting the jet and wanted to have full control over the stabs, then it was best to be at a centered trim position. But when I tested it in the ground (because SAS makes it harder to test in the air), the stabs don't max out unless I also trim. If you want to command full stab up, you need full aft stick plus ~15% aft trim and for full stab down, you need full forward stick plus ~10% forward trim, even though in the cockpit, the stick shows you maxing out the controls with a centered trim position. It gets weirder yet, because when I'm pulling full back and I reach the aft trim position required to command full stab up and then I look inside the cockpit to the horizontal stabilizer position needles and trim a little more, the needles move another couple degrees. So to recap, because I feel like I'm not explaining this succinctly, I have my trim centered and my joystick full aft. I see the ingame stick full aft, so adding aft trim does not move the ingame stick anymore, but it does move the stabs. I then keep trimming aft until the stabs stop moving (happens at about 15% aft trim) and I'm now commanding full stab up, but then I look at the control surface indicator gauge in the cockpit and put in a little more aft trim and the needles move, even though the stabs don't. And the same things are true pushing forward.
The second thing is that the stabs move up when the combat/maneuver flaps/slats deploy. This might be how the real jet was, but it seems backwards to me. I feel like they should move down to compensate for the nose rise from the additional lift generated from the flaps being extended. Because right now what happens is, if you get a little slow in a dogfight and the maneuver flaps come out, then the stabs move up. So it's as if you're pulling an extra 20% back on your stick, even though you haven't moved the stick at all. You're still exactly at the same stick position you've always had in that turn. It's akin to your trim suddently changing and I find it really awkward, because it happens multiple times in a dogfight (any time your maneuver flaps come out or go in, the stabs are going to move up or down respectively). I couldn't understand why it was so hard to maintain corner speed in this jet, because finding myself a little too slow, turned into finding myself way too slow more often than not. And it's because when the maneuver flaps pop out, the jet commands more stab up, which tries to turn so much tighter that it just dumps all of its speed and it's all without you commanding it. So I find I have to catch it and and quickly cut my pull in half when the flaps come out and the stab moves up and then once I'm back on speed and the flaps go back in and the stab moves back down, I have to resume my previous hand position to prevent getting too fast. It feels clumsy.
I don't know if these two stab behaviors are bugs or not, but I can make a video demonstrating them more clearly if my explanations aren't good enough.
Thanks
