When I engaged home mode the phantom used to to come back directlymoverhead and then keep circling above me. I uppgraded to the latest software, reloaded my settings, but now. in home mode the phantom comes straight back to me, but it continuos and flies away from me without circling. What am I. doing wrng? Tell me what the position the switch should be in, I tried home and gps, and home and manual, but same thing. Do I have to change the manual mode to fail safe mode?
