I have found while flying my Phantom that I am very thank full for the radar and the Failsafe function. I would say that 3 out of 5 times flying when I get out to 1600 ft I loose sight or just loose visual or just cant find her with my ole tired eyeballs. I was wonder if this happens to many of you guys. I have to use the radar or H/l or the Failsafe function to get her back or just find her in that vast sky while doing all that crazy flying and maneuvers that we do getting pictures and video. Do you lose LOS too.
