Just loaded this product up two days ago for X-Plane 11. Everything thing works fine with the exception of the Cessna Combo Panel (ignition, master switches fuel pump and lights). X-Plane setup shows that all buttons/switches on this device are programmed correctly. Finally, going back to the C172SP model the Cessna Combo peripheral works, as it always has. What am I missing here?

Hi, unfortunately we don't necessarily provide support for hardware like the Cessna Combo Panel you're talking about, but I would imagine there is a way to bind each button and position to an X-Plane command. The list of custom X-Plane commands can be found in the back of the manual, located in the manuals folder.
