My custom backpack for the DJI Phantom 4 quadcopter.
I travel a great deal on aircraft, so wanted a smaller, more compact backpack option for my Phantom 4.
I like that you cant tell it has a "Drone" in it, and that its small enough to slide under the seat in front on most aircraft meaning I will never have to "gate check" it.
Here is a link to the foam I used from Amazon: http://www.amazon.com/dp/B007J2JJYK/ref=sr_ph?ie=UTF8&qid=1464124153&sr=1&keywords=kaizen+foam
Its very comfortable and has plenty of pockets making it easy to store all the essentials for flying, plus extras when Im needing some extra space for traveling.
Hope it helps. Its a much cheaper, and more compact option than most others out there.
