To fly the other stock F-4 variants in WOI, you have to copy their plane folders from SF/WOV/WOE ( which hold the stock skins and a single "main" ini only) into WOI, then extract all their other files ( ini , lod and cockpit texture files) from the SF/WOV/WOI \Objects\Objectdata.cat archive ( using this tool - http://forum.combatace.com/index.php?autoc...mp;showfile=343 ) .
The aircraft files are all in the lower quarter of the cat archive.
Move the extracted files into their respective plane folder, you'll need to make a new "cockpit" folder where all the cockpit textures and the cockpit lod goes.
The plane lod files and all inis go into the planes main folder ( see attached snapshots which show file hierachy by example on the F-4J )
For testing, keep in mind that all other jet games except WOI are presently at the code level of v08.30.06 and the FMs are optimized for it, so flying with those old versions in WOI isnt representative of the new WOI code.
