Adding to the bug list....
1st Person perspective in a Hummingbird or Pawnee has no sound. Has the startup sequence sound but then phases out to no sound. 3rd person sound works perfectly.
Amazing mod just falling short for me as I am a pilot. Running stock ARMA with CBA and shacktac no other mods.
Hope you can enable the sound for the 1st person hummingbird and Pawnee soon... everyone else on my squad is having a "blast" ;)
Keep up the great work!
