There is other info spread around the DCS forums as well, but some of it's a bit buried
It seems they've changed the structure of some of the files at some point, so some info is now out of date which can get a bit confusing.
Apart from the actual model and texture files, every thing else is pretty much done with LUA scripts.
Added some more schemes. These are actually T8 Hunters, but the model is still a T7. Correct model will be added at a later date, once I get all the external issues sorted.
It's one of the hazards developing for an evolving sim. Same goes for P3d, you never know if the next update will mess things up. It's probably why some devs are reluctant to commit to it. FSX may have it's flaws, but at least you know where you stand.
I've mostly just been working on external graphics stuff, so hopefully any changes won't cause too many problems.
