335th_grWotan built this device. Can be used for 4 axis,like Throttle,trim,Mix and four buttons (toggle) etc

You will need these components:

Four (4) buttons

Four (4) pots 100kΩ

An old CD/DVD case. You have to cut the case to open holes for the buttons and for the pots (black color shows where we have to cut, black box for the pots).

A cheep joystick converter can convert pot's movement and on/off state of the switches to simulator controls.

  You have to remove  PCB of joystick converter and fit to the case.
