A:AnswerThe shipping box that this unit comes in is quite good--it is a semi-rigid PU foam with a sturdy hinge and locking latch--I would not hesitate to check it on an airliner in this case. It will hold two batteries, spare props--pretty much everything but my Ipad. Could probably be slipped into a duffle, suitcase or larger internal frame backpack as well.
A:AnswerI have the Phantom 4 now for about a month. I have taken it up to one mile so far. I have to find a good unobstructed area to try to fly further. You cannot see it after a half of mile or a little less. It is kinda scary to fly out that far without seeing it. I am taking it further out more and more. But so far about a mile without the extenders. I live in California a lot of interference and buildings.Have to go out to the desert to try to fly it further. So the Pro should go out better range.
