Very, very, very nice!
Why are you not making and selling these?
Actually I`m thinking about this, but the price gonna be about $880.
Also the system is going to be a little simplified.

how do you map all those switches? arduino magic? or something like that?
It`s got VKB controller inside. Same as Black Mamba joysticks do.

The throttle mounted on a plate, and the use of smaller boxes rather than one enormous box; genius.
How's the setup powered?
Yep, and the boxes are modular, so I can replace any of it within 2-3 minutes, when SC will be released - I`ll make one or two replacements. Pretty easy.
Also got 2 external ports to connect smth like rudder pedals and few more button boxes. )
The whole system is powered by 1 usb host.
