Yeah. It turns out that this problem is the same as the sound problem for the CS 727. So being familiar with the 727 problem made it was easy (for me anyway) to simply "give it a try", and I found that it worked.

If you do the same thing that I do when I first start it a lengthy time time not having flown it, then you will forget that you must push the joystick throttle fully forward or the "air brakes" deploy. This always causes me to crash on the first few flights. ::) ;)
