Hi so ever since i got my dji phantom 2 i never tryed testing to see if the dji phantom 2 would return home on gps mode just in case i lose sight of my phantom or lose signal does this feature work right out of the box or do I have to set it up? So how does this work? and yes i know to always do the compass collaboration on my phantom so on my remote control phantom 2 stock remote i have the left side switch to off and the right side switch to gps so if i lose signal on my remote it will fly right back to its home position where it took off right? and if i ever lose sight of my phantom just turn off the remote till it flys back to my home position? and for all this to work correctly do i have to turn on failsafe mode from my dji assistant software for it to work? or can i just always fly and keep my remote with switch set to gps and no worries? and if i do have to use the dji assistant software to activate this feature where do i keep my switches on the remote for it to work just in case i ever lose sight or signal on my phantom 2 thank you.
