A few days ago I accomplished my first totally autonomous flight with my DJI Phantom 2 Vision+ quadcopter.
Everything work as advertised, but it was scary to watch my $1300 drone sail off into the distance and becoming a little more than a speck in the sky.
The Phantom has a mode where you enter a series of waypoints on the map, and specify what altitude you want to be at over each point. Once you press Go on your iPhone/iPad app, the motors start and Phantom takes off on the defined mission.
For my first flight I entered only two waypoints. The altitude was set at 98 ft automatically. Regardless of the number you put in, the last one is the takeoff location.
Please Note: I just discovered that to ply the video properly, you must click on the YouTube button, rather than the large Play arrow/
There were several lessons learned from this first flight that I will heed in the future.
