calculation for the potentiometer

Towards the bottom is a good Labview example of slaving a Joystick to a potentiometer signal using PID. I think this is similar to what you want to do. Take a look and reply back with more questions.

It's a very nice web-page you have there.....
Anyway, the example is very similar to what i was asking.
For example: How do you calculate it so, 1.17 is 90 deg max down and 3.9 is 90 max deg up? and how can i change it to be for example, 40 deg max down and 60 deg max up?

Those are measured values. You drive your device to where you want the limit to be with a probe or indicator on the Analog Voltage and see what it reads.
