I painted it with some cheap acrylic paints that Home Depot had in the paint section. I tried to spray paint it first but that was taking forever so I switched over to the acrylics and it worked great with a roller.
The Saitek panels work with FSX, P3D, and XP10. I have heard that there is a third party library that is attempting to make them look like joysticks but I don't know how far along that is. I think the goal is to get it to work with DCS.
The gauge app is called FlightGauge and I'm working hard to get it released. The 7 inch tablet version has been finished for a while but the 10 inch version has taken some time to get completed. You can find out more about both on my blog here: http://vineripesoftware.wordpress.com
