Mine will beep constantly when I launch, if I have OA on, until I get far enough away and high enough away from me. 5' away and 6' up would still be in close when the beep starts.It's about 6' off the ground, Nearest obstacles in front and sides are at least 50 yards away, Nearest object behind is me and I'm about 5' away and the wooden house behind me is about 20' behind me.
I would take it out to an open area... was away 15 ft or so... and launch it up to 10 ft. If it still beeps, then there is a problem. But I'd almost bet its because you are standing to close with it hovering to low.
