Well, since I can imagine that the sound is a very expensive thing to implement, and considering I have recorded many planes in video with sound, I feel in the debt to freely offer (giver the right to use) all the engine sounds I've recorded, and this public ofer goes to:
- 1C Dev Team
- Daidalos Team
- Modders
I mean you can use sounds I've recorded, like this one:
Or this one:
You can dig into lots of videos I have in my Youtube non-music aviation channel:

If you are interested in using a sound, you don't have to ask me. You can download the video at the highter resolution (so Youtube lowers the quality of the sound in low res), and the only thing I request in exchange are credits if my recorded sounds are used.
Hope this will help...
