instruments are setup differently,
As in scripted so if a user wishes they can export MFD displays or radar scopes easily to external screen.
Collision boxes are setup in max,
Textures are different.
Cockpit and external meshes are actually ONE complete scene,
Exporting to edm exporter is stricter than TWexporter.
Materials and Textures are setup differently in Max for DCS.
Data Files are similar to TWs inis, but the strings are different, and use different syntax.
So the models are done, but he'd prolly most likely have to re-configure every material after Merging the Pit and external model.
then go through the plugin data files and write them all (filenames and links to model files etc etc),
then re-write his flight models to DCS's format.

However, ED has a viewer Application that lets us see the model in the game engine without having to load up the game .. ahhahahaha
