Good evening everyone,
Since I am working on a big collection of different MiG-15s and MiG-17s for different nations. I found MiG-17 realistic flight model tweak which limits the maneuverability of the MiG-17s at high subsonic speeds, especially above .8M. According to them, I have to look at CLa= and Cmq= tables for the stabs at values .8M and above.
This part still confuses me. So I am asking for someone to point me at where to look at. That way, I can understand which codes to tweak for another MiG-15 and 17 that still doesn't have the maneuverability limitation at subsonic speeds.
I opened MiG-17's data file and went to [AircraftData]:

May I ask, which codes limit the Elevator responses at certain airspeed (Mach 0.8 and above)?
