Phantom FC40 Downloads
Hello I don't wish to put a spanner in that but here in England both I phone and normal Android phones don't have the old App for the FC 40ty I personaly phoned the Apple people to ask why

the strangest thing is we can still buy that little camera on evilbay uk
all I do with my little camera is set it to wyfy and watch for the orange light to come on like it's
looking for the wyfy it makes a video once you fly the Phantom,
the next thing is connect it to my laptop and view the video it does it in loop sections
but you do get all of your movie
I hope that you did't mind me jumping in
you might get it on a old mobile but the newer ones it's a No No
