I seem to be having issues with the BD-5J, when the plane takes off it stalls shortly after takeoff while flying perfectly horizontal to the ground. I am applying full throttle, rolling 5 degrees, reaching about 150k, then suddenly speed drops quickly and falls to the ground. This wasn’t happening …

I found the fix, go to general options and change the flight model from legacy to modern. That will fix the issue. Sometimes when the game updates it changes this setting. Let me know if it works.
