Military joysticks will vary in the exact degree of movement. Set the F18 to whatever fits your cockpit and feels right. If you use stops with setscrew adjustment, you can change it in the future if you must be precise. No pilot really cares as long as the plane flies correctly. I built the first civilian F16C simulator in 1992. It was a real mess making the compression joystick work on a pc. You won't have any trouble with the F18. It has about 16-20 degrees of total movement. Unfortunately, I had to stop flying because I went blind in one eye. You won't have that trouble, either. Good Luck!!
