The original was made by Tiger_33 for the IL-2 Sturmovik flight simulator, with the exception of a few samples. Thanks to him for giving permission to use his sounds!
Here is a list of "soundbanks" used for each aircraft:
Bank_047 -> Rustler, Stuntplane Bank_048 -> Light aircrafts flying AI Bank_114 -> Dodo, Skimmer, Cropduster Bank_128 -> Nevada, Beagle Bank_129 -> Heavy aircrafts flown by AI Bank_132 -> Hydra, Shamal, Andromada, AT-400 (sound_011 and sound_012 only)
However, you can use some unused banks and then set up the bank associated with each aircraft using the VehicleAudiodata program.
