I optimally approached as the only drone. I think all the possibilities for non-pros are enough. The joy of flying never goes away. I think a non-combo version may be suitable for many, since from experience you rarely fly more than 1 time per day. A flash drive is needed only as indicated on the off site, that is, with a good speed. inserted the old one first - it doesn’t work well, although I also wrote on the old camera in 4k
