Often when I add an aircraft to FSX the gauges are either entirely missing, the gauges are there but they have nothing in them, or the whole panel field is black. Can anyone help please? The DX10 box has been unchecked and that generally solved the white textures problem.
Check out the read-me that came with the download.
Some aircraft need the gauge folder included with the aircraft in the aircraft folder and some need the contents of the downloaded gauge folder put into the main gauge folder.
You can do both (no harm) and see if they show up.
