Twinboom has a great Flap and gear sound in his well prepared sounds packages but it is cut short when used in the game. Note that if you go to "Game Sounds" then "Advanced" and play the gear and flap sounds using the "Test" button it is indeed the full length sound. At the end of the P38 gear sound is a subtle thumb and that is what is missing.
I thought about making this a wish but was not sure If I was doing something wrong or just poor hearing. If someone else could verify the problem that would help.
Any thoughts?
