when I’m flying aircraft swing too much, they get too upright and hard to control
Make sure you’re using the Modern flight model in Settings. If you’re still having trouble controlling the planes, check your controller sensitivities. If you’ve never flown a desktop simulator before, I highly recommend the flying lessons to help get you started. Once that’s complete, work your way up. Do some flights with the 172 and get used to that, then something like the Baron. Keep working your way up. That’s how real pilots do it, and that’s how I did it nearly 20 years ago when I started out in simulators.
