Finally a sim where the sound pitch correctly changes with RPM and not with MP like FSX/P3D
Unfortunately the governing range is way too small and RPM starts to drop already at medium to low power settings, even with the prop at high RPM/low pitch settings.
It's worst with the C90 where this happens at rather high power settings.
Flap pitch moment on all planes except the C172 reversed, up instead of down.
On the 172 there's also a pitch up moment, but in that case this is correct.
