Dave, it's just the 1972 version of the F-4D - it has tape lights built in which are constantly illuminated, plus the Falcon or AIM-9 rails if they are selected. I never got around to make a decals and markings pack for it yet, and X RAY PMed me about a markings project for that version, so I said that he was welcome to release it with his project. It will have the same credits to you as all the other versions did of course. I found an error that required a separate decal on the stab top but eliminated it by rotating the mesh part so no "top" exists. Also noticed a problem with the underwing hinge area - fixed. I am updating all the previous versions and will pass along the source files to you of course if you'd like them. They could use the touch of someone who really knows what they are doing, and many would welcome a 2nd generation version I think. AND, some hi-rez textures of course...
