Excellent iteration of an excellent mod.
I noticed one thing though and I'm not sure if it's intentional.
The head roll inertia, that is, movement of head relative to the forward vector while the plane is in the roll, is reversed in respect to previous versions of the mod and the default game behavior.
For example: Before, when you initiated right roll while looking forward, the whole picture would roll slightly clockwise, as the head roll is lagging somewhat behind the motion of the plane. The position of head would also be move slightly to the left, as the head is somewhat above the roll vector and the whole body has some inertia that makes it lag behind the plane roll.
That seemed intuitive and correct to me.
Now in this version, the opposite happens, as if the head roll precedes motion of the plane, thus a right roll makes the picture rotate counter-clockwise. The position of the head still behaves like before, making it look as the body has it's usual roll inertia, but the head is rolling *into* the plane roll, perhaps as if pilot is anticipating a roll and leaning his head into it to compensate.
I find this new behavior disorienting, so I'm not sure if it's intended that way or not, maybe a bug involving a wrong sign somewhere in roll inertia calculations.
I hope I'm clear enough in my explanation, if not, I can post some screenshots tomorrow when I'm on my rig.
