If u have any other flying simulators...that youd think has better sounding engines or what not?...you can actually take that wave file and put into your AH sound file...i did that along time ago when game 1st came out...cause alot of the engines sounded the same...before all the updates and new wave files, but i had a game Total Sim on disc, and some of the aircraft and guns on that game sounded more realistic then Aces High did..at that time.
