I'm looking for a backpack, or a way to transport the P4, for long day and maybe even overnight hikes. A pack or method of packing that does everything EXCEPT for being carry-on specific. It needs to have room for the P4, RC, 3+ Batteries, DSLR + Lens, Water Bottle or Camelback, Snacks, Tripod and Rain Cover. I understand this would make the pack heavy. What about for overnight hikes? How do you transport your Phantom and photo gear?
