It can show knots or km/h. In your track IAS was 230km/h and i got same speed when i tryed with emergency AB, but you was right DCS Mig21 can maintain level flight at about 40 AoA.

Do we know is this realistic or not. I made same test with SU-27 (default fuel and ASC direct control enabled. I was able to hold level flight 40 AoA and IAS 107km/h even without afterburner. With afterburner i started to climb. I think this is not AoA subject more likely thrust to weight ratio.

Ok now i see how you did it. Second stage AB gives extra thrust, i did not use it. I tryed also and i was able to get same performance. IAS is not 400km/h, with tacview it gives 230km/h. I dont know is this realistic or not but it seems that DCS Mig-21 can do level flight 40 deg. AoA with second stage burner.

I would like to see track.

No afterburner dont give enough thrust to maintain 0 VS. Go ahead and try. Maintain 0 VS and slow speed and AoA start to increase. At some point you need to add throttle to keep 0 VS. When you reach critical AoA and wing stall even full AB is not enough to go out of stall. You need to lower you AoA.

Pls show how to perform endless Cobra. i can't. I can maintain very high AoA but i will loose altitude, more than 10000ft/min.

No you can't maintain zero vertical speed after critical AoA. Not possible even with full afterburner. deepstall.trk

I quote from book. Author Jyrki Laukkanen Finnish test pilot, 732hours in Mig-21bis."The aircraft is very spin resistant and it is hardly possible to get into any post stall gyrations without positively applying full rudder and full aft stick at high angle of attack; this makes no sense anyway. We never spun the aircraft accidentally or intentionally either. There is no need for this kind of maneuver and so no need to practice it."

Wingman makes strange and dangerous movements after takeoff and sometimes crash. takeoff.trk

Hmm, i could not reproduce behavior again. Maybe it is working well

Ai wingemen(A-10c) try to refuel all same time and collide behind tanker.

After latest (1.2.16.42215) beta update UH-1 module stopped to work. Game dont launch and it gives error dcs stopped working. Does others have same problem?

Yes too weak wing, or pilot have too much muscles, so wing can be ripped off.
