Input signal control adjustment circuit

Input signal control adjustment circuit

I am using a RoboteQ controller and I would like to make my input control circuit more robust without changing any of the feedback setting. The input is a joystick with a 5volt power source and the signal is set at 0-2.5 and 2.5-5. This works fine but I would like to reduce the input so there is some adjustability in the control.

In ideal solution would be a box or circuit that would de-amplify or amplify the input signal by adjusting a pot or flipping a switch.

Any suggestions would be very helpful.

Did you try the circuits that were supplied in your first thread?

I tried the first design but I would also like to limit the output signal as well as increase the gain of the signal. Well the first design limit the output?
