I wouldn't Trust what some people say about FAA registration (online, retail stores, hourly employee, etc), it's ALL there (answers - get the Facts) when you go to FAA site Link I sent you (if you Don't Register & are caught, it Will Be All on You)!
Commercial Requires Also you Register AND to do Commercial drone Flying (i.e. getting paid for it, contract, etc.) you need to get the FAA Part 107 Certification (requires 2-3 Hr. FAA written test). Yes Insurance Grif, it's thru State Farm for $60.00 Yr - Not bad, considering it's avail out there (ebay, amazon, dji site, etc for allot more). Yes, it is a bummer that I we can't fly the drone where I'd like to (great pics, videos, etc) in CO parks, etc (least for now anyway, rules may change)?
Funny, I also have a S. Note 4 I use (great ph & presently the Only S Samsung (& Note) that Does Have a Removable/Replaceable Battery (Note 8 coming out?). When I do upgrade to Larger screen - I'm thinking something around 11-12" screens (& get an adapter for my controller for the larger screens). I am more of a PC user (after all it is a PC world) but iPads are real nice (More Expensive for the same PC comparison power/features, etc). But Macs probably (I think) rule in the Music/Video software realm!
Haven't gotten to video editing as yet, probably wait till I'm better at flying 1st but if I was going to Choose (I researched & think), 1 of the very best is the:
Adobe Premiere Elements.
I wouldn't steer ya wrong; I'm very Tech savy, straight forward, detailed & an excellent researcher (allot of what I do at work) kinda guy!
Hope all this will help you out? What are we here for...
Best,
