TLDR: Fixed engines for closer to real values. Flight performance was tweaked for more stable, "cruise style" flying. Removed the all-time cobra possibility.
This mod is not meant to be realistic or study-level performance; MSFS is still focused on subsonic airplanes.
Engines were tweaked to have closer to real output values and be more responsible for throttle.
Afterburner uses a lot of gas, so don't expect 1000 NM on full AB.
The flight model is tweaked to have more "USAF-style" flight performance. Actually, plane behave like it has eneabled AoA limiter all the time.
It can achieve 30 degrees of AoA at a slow rate, but the bleed speed is significant.
I recommend not exceeding 16.5 AoA on slow flight and 5 AoA at 0.8 Mach +.
Of course, you can break 12G or more, but without FCS implementation, the plane is still piloted in a direct way.
FBW is not enabled; West systems are different from Su-27 family FCS.
Known bugs:
1. RPM indicator shows 20% at idle. Should show 70%. But this is Deimos .xml business to fix that (I don't have access to files).
2. Speed parachute can be enabled in flight - it should have something like weight on the wheels to work properly (moan to Deimos fix).
3. Sluggish near 1 Mach - added 10% of power in 1.01
4. Sluggish near 2 Mach - added 10% of power in 1.01
5. Fuel system, geometry and CG could be wrong - plane is encrypted and developer mode not showing basics...
6. Afterburner cocpit lights, sound and nozzle animation start at 95%. Sometimes you can fly at MIL and have AB effects on. (locked xml's ...)
