I just flew with a squadmate online and found some bugs, at least I didn't see anything about that in the manual:
- The EOS works
- target designator moves left-right
- HUD range is selectable same as for other russian planes from 5 to 500km
- G-limiter doesn't work. I can pull like crazy, g-load goes extremely high, AOA goes in the red sector, a/c looses speed extremely fast (like 100km/h per sec). I was able to do some sort of a cobra.
All is OK in single player - no EOS, no left-right slew of the TDC, only 25km HUD range, g-limiter works normally.
