This happened today. I'm flying the H. About 100 feet up and not far out at all, maybe 75 - 100 feet away. The screen on the ST-16 goes black and at the top of the screen is "Flight Control Lost" That's it! I look up and the H is still steady and in a couple of seconds (that seemed a lot longer) the screen reappears and all is well. ANY ONE have this happen? It changed the color of my underwear.
