As a complete guess I would imagine your issues, which you might want to elaborate on, could be cleared up with a lot of practise, as well as reviewing your flight controls. If you don’t have a high spec yoke/joystick/rudder pedals you may improve your experience with tweaking the response curves.
Another tip that may help others to help you is to add something to your profile that shows what hardware you are using. if you click on my name, it will give you a portion of my setup. This would help others so they don’t have to ask what CPU you have, or which joystick you are using, that sort of thing.
