Meant to be Seen

I have an old Saitek Aviator joystick. I'd like to press a keyboard button in order to set the X axis (or Y or Z) to a certain position. Is this even possible? I've been looking at new/old UCR, UJR, Ahk, etc., nothing so far.

**I want to do this WITHOUT vJoy if possible**

If you have the physical joystick, then the values reported will be determined by hardware (although they can be somewhat manipulated with calibration). To provide joystick values programmatically, you need a virtual controller, such as VJoy.
