The DroneGuard CS 400 |$149 from Amazon| provides something for all those DJI pilots who've had their shoulders ache after hours of lugging a case around.
This is designed for the pilot on the move by Lowepro, a venerable standard in photography gear. We've all used traditional carrying cases but with a full day of shooting, sometimes a little portability can go a long way. We've recently checked out ways to save our back from some of that pain and a backpack case like the DroneGuard kept coming up. Anyway we can make a day long shoot more comfortable sounds good to us!
If you're looking for a convenient, safe way to transport your DJI Phantom 1 around then you'll want to give this backpack a serious consideration.
