STT, I agree with ollie. You absolutely nailed everything but the sound. I love having a Huey that doesn't turn into a Black Hawk at long range. Great stuff, especially with the M60s in the doors.
I seriously think, and I know I've told you this before, that Martin's Huey sounds are far better than the one you shipped with the original Nam pack (and this one is pretty close to the one you used before). It does sound cheap and grainy. I remember that you justified it last time as being "more realistic", but I live about 10 miles from a National Guard base, and they fly Hueys. I can personally say, as they've been flying over my head for almost 2 decades, that Martin's sounds are much, much closer to RL Hueys.
So do you think you could just use Martin's sound? If you did that, this would be the best Huey, ever (at least until you release the rest of yours).
