TT,
Sorry bud, wish I knew how. I had some great "power-dive" samples but the way AH is written the diff throttle settings are merely frequencies of the base engine sound. So thats down in the code not in the samples.
Maybe if they added a new sound for overspeed like they have for the stress groan. Blend it in and out.
overspeed.wav....hmmmmm.
Regards,
Wab
