Just curious, there seems to be lots of issues discussed in this forum whose answers are clearly addressed in the User Manual. Who on this forum actually carefully read the manual before their first Phantom Vision+ flight? Know I read it at least 10 times before my Phantom even arrived, (it took 3 weeks after ordering) having downloaded the pdf version from DJI web site. Still have to refer to it often. Maybe that's because I'm an old man with failing memory, huh?
