ok i gave it try. I copy/pasted from the mig sound script to the ah64.js and I downloaded Jskoker sound files.
So far the sound works but i only have the outside sound working and the blades animation is frozen. It's probably just a small detail that i failed to comprehend. But again, i'm sure Pyton or Levi could fix it easaly.
If you want to try just drop the attached ah64.js (make a backup of your original) and download Jskoker files.
