This is one of my favourite aircraft and was very happy to find that I could use it in P3Dv4. I substituted Doug Dawson's dsd_p3d_xml_sound_x64 which enabled switch sounds.
The only thing that doesn't work is the throttle lever animation which does work in P3Dv3. The throttle function itself is ok so it's flyable.
Just wondering if anyone has any idea what could be causing this please?
