Frustrated at not being able to find just what I want on the open market, I've started thinking about the possibilities of making something of my own.
I aim to create a unit that provides three rotary controls for trim (elevator, aileron and rudder) and a number of toggle switches for other functions (lights, gear, hook, etc)
I'm pretty sure I can build the box itself and even install the various controls, but I'm worried about the electronics as I have no background in this area at all.
Looking around at some of the options, X-keys Matrix Boards look as if they would be the way to go - apparently they are nice and easy to use (ease of use is something of a relative term, however...

Does anyone have any experience of this hardware, and if so do they have any suggestions on how to source appropriate switches, potentiometers, etc?
All the best,
Pads
