hi well after a bit of trouble i am ready to fly again.firstly i took my pv2+ out in open field .flew for 10 min then landed left approx 2hr then new battery full and proceded to fly.got up to 60ft and all ok.then upto 200ft the lost sats and app stated lost contact with controller. so i switched to fail safe but what i thought was staying at altitude and drifting ,was not. i have now watched the recording and it was very slowly decending and auto landing.it drifted approx 1/2 mile away and landed out of site.but unfortunatley landed on uneven surface,causing it to tilt to one side and burn out 2 motors and melt the bottom shell.so all replaced with new.but reading the manual.i dont under stand why it didnt return to home.have set this in the assist.so why didnt it respond to any of my inputs even tho i switched to fail safe.should i have switched to atti to regain 2.4ghz to guide it back my self.?
