Goals to think about when deciding on a way to carry your drone stuff around.
1. Must do a good job of protecting things, but keeping in mind it will always be on your person when traveling, so you will be protecting it yourself to some extent. You'll never check it when flying somewhere.
2. Must fit into an airplane overhead storage, the legal 9X14X22" size. Most hard cases won't qualify, but many airlines accept them for carry-on. You risk getting rejected on heavily booked flights, and batteries cannot be in checked bags.
3. Should be comfortable to carry your drone stuff when hiking or biking. The ideal setup is a backpack.
4. Good zippers, EASY to open and close. This is hard to determine from a website, you really need to test it, or have easy return privileges.
5. Good quality shoulder straps that are high enough quality to last a few years without tearing apart.
6. Enough room to carry all your stuff, including the charger and multi-battery charge cradle, essential when traveling.
7. Light enough to be easy to backpack. With all contents, under 25lbs is ideal
8. Must be non-descript. You don't want anyone knowing what's in the backpack. It shouldn't have a drone embroidered on the back, DJI, or anything that hints drone.
9. You don't want any labels implying "high dollar photo equipment" is inside the backpack, such as a "National Geographic" logo.
10. Good handle on top for hand carrying in addition to the good shoulder straps.
11. Configurable inside to adapt to the gear you have.
12. Good materials that are not fragile, strong enough to last.
I like the
Think Tank Helipak for to meet these goals. Not cheap, but less than the
GoProfessional backpack that's not configurable, and lighter.
