They call it "auto-home". When you start it up, you calibrate the
compass, and it records the starting point. Then you're supposed to just
push the "Home" button, and it is supposed to fly back to that position
and hover.
When it started flying off into the distance, he pushed the home button,
and it cam back, but it was off by 20 feet or so, and it tried to land
in a tree. Not optimal. he was able to push the "up" control to prevent
it from actually landing in the tree. However, he was not able to
maneuver it to the appropriate landing spot.
As I and his other uncle were diving to avoid being hit by the thing, he
was able to land it on the roof of his house without damaging it.

Saw a thing on the interwebs yesterday about how to not crash your
drone the first time you use it.
Apparently they have something similar to an E Stop button that turns
on the autopilot and flies them back to the starting poitn.

FHSS maybe? Or possibly small channel size since it needs distance,
not throughput.

My nephew got a new DJI Phantom 3 Pro model drone, and in the
process of setting it up, I was trying to find the WiFi
frequencies/protocols it was using to communicate between the
controller and drone. Nothing showed up in my sniffer, so I wonder
if it's using 802.11 at all.
The specs
(http://wiki.dji.com/en/index.php/Phantom_3_Professional) say it's
using 2400-2483 MHz, but is only 100 mW EIRP. They claim 2 KM
range, but he lost control of it in his admittedly WiFi congested
neighborhood.
