I want to test the "return home" feature on the Phantom 2. Am I correct to just flip the remote control switch off while it's flying and that's it? To regain control, do I just flip the S1 down??? Do you leave the S1 switch down for the rest of the flight or flip it right back up? Does the Phantom make a nice soft landing on its own, or are we risking a rough landing and possible damage in the return home mode?
