Thank you for saying that it's possible to get rid of but I don't know where to even start looking for the .wav files and once I'm in the air it doesn't stop and sometimes on replays it makes that sound. The closest sound to it is the flaps up sound, which I kinda don't want to get rid of.
Location: FSX>SimObjects>Airplanes>Carenado hawker>sound>Carenadoflaps.wav I'm going to test it out
