hi, i use nothing but default. when i start, i start on parking place, and i always see that, from start walk around or when use default external camera in ms20 it's end in my ms24 profile all from ms20 + walk around map triggers.
for get that pitch axis autorotation in the velocity x, you just stall it at minimum power, then push throttle full forward. easy to get, and easy to avoid same as any aircraft that have that asobo disease after they kill dynamic in su10, in su9 we had opportunity to have a normal spin, and have flat spin in aircraft that can do that, after su10 most of aircraft lost that opportunity and get this knife-edge spin, usually inverted(negative g) in the velocity x just positive g direction autorotation around pitch axis. as you see in video. same as other asobo su10 "reform" victims, it's drop wing and start autorotation in this highly unnatural way.
thank you
