Were you able to get the Aerolite 103 sound sorted out? I agree 100% it sounds like sh–. like a home generator. I asked the dev about it and they just gave me a snarky reply that they pretty much don’t care how it sounds. It should be easy to alias to any of the rotax powered light sport aircraft in the game, but reading the thread here it looks like its a somewhat difficult process. they say its easy, but it doesn’t seem so. If you have a better sound set, or file tree, could you post it up on Flightsim.to?
