Has anyone has taken the plunge and tried to "extend" the functions of their CH USB Yoke by adding new buttons/levers/switches?It seems that it would be possible to access the built-in USB interface of the yoke and that this interface likely has room for additional input devices. Anyone already played around with the guts of this system?

Yes, I did. I added an outside throttle that I built and operate it through the CH Products yoke. Here are some pictures of the CH Products open and one of the throttle assembly I built that is connected via the serial connection on the side of the yoke.The switch on the side allows me to choose the CH Products throttles or the external throttles.Johnhttp://forums.avsim.net/user_files/80496.jpghttp://forums.avsim.net/user_files/80499.jpghttp://forums.avsim.net/user_files/80500.jpghttp://forums.avsim.net/user_files/80501.jpg
