Very cool!! I'm going to carry mine up to the summit of Mount Agung later this year. Look forward to seeing your experience! This should be EPIC!! As for the Phantom 4,, it will have different lift properties, but, I don't think it will be anything you should worry about other than keeping it and batteries warm before flight. My dive buddy on a trip to Galapagos had just returned from base camp at Everest and based upon what he described, you best worry about your own health first!! Haha,,, altitude sickness really affected him seriously at base camp. So,, be careful and drink plenty of fluids!! I can't wait to see that footage!! You and your P4 will go Viral!!
