To not get nervous about losing your drone?? Lol... I just got my Phantom 2 NV last week, and took it on my first "real" flight yesterday. As it was ascending, I was getting nervous about how high I should go and all that... worrying about losing signal, fly-away, all that stuff. I bet I didn't get it half as high as I could have, but I'm not use to guesstimating altitude yet. I am REALLY loving this thing! Onward and upward!
