It's quite easy to use the mini-stick on the throttle to control GVs. Just use a basic script that allows you to bind keys and that's all there is to it.
Here is the script that will allow you to program the WASD keys to your mini-stick.
In Control Manager, click on the CMS Control tab and program the WASD commands in B1 through B8, tailoring to suite.
ack-ack
That looks like a script to make it an eightway hat (you only need 4 for GV), great for views
You don't even need to write a scipt file for 4 way!
Just uncheck the dx mode for the axis. Set increment to 1 and on inc / dec set S and W
Thats it!
You can do the same to the with A D or keep the axis for finer control.
It seems that not everyone is aware of the special function of 1 increment which makes the axis a keypress until released. And on a centred axis like the mini-stick that means you can set a key for increased axis value and a key for decreased axis value. Why sciprt when the boxes are already there in CH Manager?
