Using a flying simulator over a regular flying video game is very beneficial. First, let me tell you that using the keypads on your computer is fine and works great but if you are in a position to be able to use a joystick while flying, set one up.
The sensation is awesome. You have much more realism. There are many companies available that provide the best joystick online. You can easily buy joysticks from various online sources.
You have to be sensitive as you correct yourself as you would in real life. If you get too excited and try to correct yourself too fast you will pay the consequences just like you would in real life. Do this once and you'll learn. As they say, practice makes perfect.
Most joysticks will come with a set of peddles. Practice using these also. After you fly a little bit using the joystick along with the peddles you will be a pro in no time. You will also have a lot of fun along the way.
There are many different types of the joystick on the market today so picking the right one for you is important. Kind of like picking out a car to buy. You have to find the one that is comfortable for you. You'll have a better experience also and you will do better. Those are just a couple of reasons why a joystick is much, much nicer to use.
