like every flight sim I've ever used, the elevator sensitivity seems way off. Adjusting it in game doesn't help.

It's a god awful path this time to the aircraft config files, however. For steam it's - users, user name, app data, roaming, microsoft flight simulator, packages, official, steam, asobo aircraft, sim objects, airplanes
