It does, but you have to change the animation as well. You will notice when you
suddenly have to step into the other pedal to stop the jaw...
So it is more an animation issue.

So much as I know this is more a nasal thing, as the YASim-heli-fdm don't have
support for engines, and this is faked by a nasal script. This "position-deg"
is more for animation. (The bo105 uses this, the s76 make use of rotor-rpm for
that as an example)

Yep!
The YASim-heli-fdm simulates all things very accurat except engines and
vortex-ring-state!

I hope I could help, maybe Maiks reads here and can answer further details.
