in case you have not flown model helicopters or quadrocopters before, I would strongly suggest, that you buy a small and cheap quadrocopter first, ‘cause there is a real chance that you will crash your first model into pieces.
Then, for the Phantom are rotor-protectors available. A set is around 25 EUR
and while not having tried them, I think they would be a good thing to buy. If you are so far from the source I would also think about buying a spare landing gear.
There are quite a few alternative mounts for the GoPro available which you might want to consider. If you don’t want to invest too much, there are also rubber sets available, to decouple the GoPro from the copter and get a steadier picture.
That’s all that comes to my mind in this moment.
Good luck and good pictures!
