I installed such a mike in my aerobatic glider and the gz don't move it around at all, even flying unlimited level stuff. Of course, I don't have a high background noise level to worry about ;-) but this does do the job of holding the mike where you want it. It's easy to position the mike so it's close enough but not in the way. Interesting idea on the Panthers. I'll have to look into that.
