they are modestly fool proof now but you are probably spending 500 quid plus for something "good". although the phantom 3's are decent buys now as everyone is dropping them to get 4's, well worth a look if you want to have a dabble on a used one.
the new phantom 4 is about 1200 quid but really is plug and play if you like DJI stuff.
i don't like my current phantom and DJI hex so i've got one of these coming to try.
bit more expensive than the phantom 4 but has more features i want, but the phantom is good out the box no question and has other features this doesn't....swings in roundabouts.
anyway...get one bought...GREAT things!
i will have the above one at easdale if they release it on time if you want a look.
