I want to buy an i1 Model: d with both controllers. Where would you recommend I purchase through? DJI directly or Amazon? Also: 1) Any recommendations for insuring the i1? 2) Is a case upgrade necessary if I don't plan on traveling via airplanes relatively soon? 3) How many batteries is necessary for 45-60 minutes of flying? I'm guessing 4-5? 17*5=85 minutes of total flying time, but that's in ideal conditions. 4) Is there a mod (modifying/hacking/creating) (-moderators) group in these forums? I'm more of a hardware guy but would like to chat with software experienced pilots. 5) Video editing software recommendation(windows)? 6) Any other software recommendations? iOS, PC? 7) Of the recommended tablets which do you like best? 8) Any upgrades or other necessary accessories?
