Got home last night and decided it was a perfect evening for flying. Got the bird up to about 250' and commenced to survey the neighborhood. In my haste, I neglected to pay attention to my signal. Was flying along enjoying everything when the screen on my iPad went black and the red signal warning appeared. It flickered in and out and the bird was spinning furiously counterclockwise. By this time my heart was dropping. Then I realized, I'm standing BEHIND my house and the drone can't find the signal. So here I was, in my lounge pants no less, running through my neighborhood trying to regain the signal. Finally, got her back home but a scary experience nonetheless. Just thought I'd share how dumb some people can be. LOL Three words... Line Of Sight!
