Sorry, Knoche, your posted A1 still does not work in BAT. If this is what you were running, it worked by chance because of other mods you may have?
It appears as if the java is from a completely different source than that 3d, it does not fit together.
The path to hier.him is not correct and the flight model path should point to the buttons directly (an A1.fmd is in there).
Also, the gear animation is bugged, the small struts animation needs rework, probably a mesh naming thing, and no external loadout is showing.
Edit: I just saw you pulled the post while I was typing
Edit2: I also found out that there is an ancient Fw-190A1 cod file hidden in BAT. So unless you use a a cod-proof class file or your own cod, no loadout change against this cod will be possible. It has nothing to do with any previous issue though.
