I can't help but notice that only a couple of people have complained about the sound QUALITY. The glow engines all seem to use the same sound file, and it's like a sound you would expect from a fischer price toy plane. I for one am quite pi$$%d. You would think that buying the most expensive SIM, it would sound at least as good as G3. Yes, I am using the sound blaster audigy 2 zs gamer. I am also using the latest drivers and tried changing acceleration. Thats not the issue, its just plain crappy sound quality. The sim itself is awesome, but would be nice to not have to hit the mute button, or get mad and go back to G3 to get the good ole sound of a 4 stroke.
