What I do is reduce throttle to zero with the left stick, and hold it there until the motors stop. To do otherwise risks the Phantom toppling over, as others have said. In fact, I believe many individuals experience this flip over at landing because of their stick shut off routine.
I am not advocating this, but on relatively windless days I hover my Phantom and/or F450 in front of me, and, wearing a neck strap on my tx, reach out with my right hand, secure the leg of the craft in a good grip, and shut down the motors with my left thumb. Easy-peasy. Do NOT do this if you are not wearing a neck strap or transmitter tray.
On windier days, I land it on our picnic table to be safe. On REALLY windy days, I land it on the grass. I'm 60 years old and although I'm in great physical shape, I hate to bend down! :lol:
