I have had serious problems with SU3 that didn't exist in SU2. The most recent one was throttle shutdown when I raise the landing gear on a King Air or bonanza. I'm on a Windows 11 platform. Also, warnings about VFR flight plans not being loaded in avionics -- "just advisory". The plane goes into a stall, and crashes unless I recover by lowering the gear and exiting autopilot. But when you raise the gear at 100 - 200 AGL, it's like the impossible return, there's not enough time. Everything seems to work on a 172. I'd really appreciate and advice or guidance about. I have returned all the controls to "default" configs. I'm using HOTAS i controls. Thanks in advance.
