Flight Model Exploit? Wing Sweep Manual Override in BFM.

Aye, 30-31 compared to 35-36 IIRC

 

And that's including the large-a$$ lifting-body of the fuselage that's not changing at all.

If you're looking at the wing only, the difference between 22° sweep and 68° sweep would be more pronounced.

 

IIRC the wings of the F-14 are relatively thick, so once they're going into Mach critical areas ( =/= critical Mach) of the flight-envelope, there will be performance-losses.

The higher you go, the more this effect matters (lower IAS for given Mach).

Yep, right on all accounts!

LOL! 
Seriously though, no point going that fast. I mean, i can see it making sense in the A, as your energy is hard to recover once you bleed it all off, especially bellow 360 knots, so you want have some spare, just in case bugging out becomes a good idea or something. But if you dedicate yourself to a one circle, don't enter a merge above 400-420. Even less if you are willing to risk it. Your bandit is an AI, right?

Wing rate slows the more you load it....e.g add G..the less the G the faster the wing sweep.

Wings forward..low induced drag per alpha..from acceleration pov, more parasitic drag... this is a high ASPECT RATIO (7.28) think A10 or glider .. low thrust requirements for STR..why? Low drag vs alpha

Aero lift center slight forward..really gets off loaded with gloves at sweep less than 35

Wings aft, high induced drag...think Delta wing..Mirage , F15..lower parasitic drag for acceleration..this is low aspect ratio. Thrust requirements High for PS=0 for STR...high induced vs alpha.. f14 aspect ratio..2.58.

Aero center moves aft stability increases as wings move aft. The gloves offset this for transonic and supersonic turn performance...

As a general rule? Yes. 

In this case, not quite. Cd for 11 degrees alpha (true) at 22 degree sweep 0.2 at low mach (bellow 0.5). Cd for 12.5 degrees alpha (true) at 68 degree sweep, 0.2. Exactly the same. In this case the alpha induced drag for high wing sweep lags behind the low sweep, fairly proportionally, until very high angles of attack (close to stall). It's the Cl that's rather higher at low mach,  1.02 for 11deg, 22^ VS 0.89 for 12.5deg 68^, that gives a better Cl/Cd with wings forward then wings aft. 

However, as you mentioned, the increase in mach will add to the drag component (parasitic in this case) which will nullify any lift advantages for the purposes of excess power (Ps), so worst sustained turns. The advantages of increased lift remain though, so higher available g's (but not sustainable).

Late to the party on this one. Locking sweep is about the stupidest thing you could do. Limits your options. Energy management is exactly that. Rapidly changing your energy state to your advantage, not staying in the state for STR. These guns only fights are giving people a false sense of what ACM is about. Try starting with a bandit at your 7 o’clock 3 miles out. Something lighter and more maneuverable with heaters. You will quickly see that all of this crap goes right out the window.
