Hi,
As much as I like CS707 work, something in the sound doesnt seem right. Specially inside the cockpit, accelerating full power, climbing, idle power, etc.

I flew 707s in my childhood many times a year but my ear is not precise to recall just from memory so I watched several 707 cockpit videos in youtube and compared to CS707. I invite anyone to do the same and check. The Captainsim sound seems more grave, bass tuned...while the real has more sharp whistling loud tunes. In cruise the main sound is wind. But on apporaches, climbing, take off taxiing I can spot big differences between the sim and real.

Im downloading a freeware sound set and will try it to see if it improves, or at least tweak and rename wav files changing those apropriate.
