Actually, you can make the Cyborg Evo a lot better for flight simulators by removing the springs, both from the twist handle mechanism and the main gimbal spring. You'll be surprised at what a difference it makes for flying. Basically it removes the need for trim, at the cost of requiring a good button layout that lets you keep your right hand at the stick at all times - but that's where it should be anyway, right?
I myself would prefer a friction lock joystick rather than one that returns into more or less (usually less) clearly defined center position. And what I mean by friction lock is the same kind of mechanism that is on Cyborg Evo's throttle; you can move the handle smoothly around the range of motion and when you leave it, it stays where you put it. That would be rather awesome.
...Also, the trigger can be fixed with some effort; you need to open the handle and fix the plastic piece that holds the trigger switch in place, and then reinforce it with some padding. It tends to cave in after prolonged heavy-handed use. Duct tape seemed to do the trick for me. I also made sort of packers with layers of duct tape on each other that would prevent the trigger from being pressed too deep, and it seemed to work fine.
