After seeing your retirement & Putt unveiling videos it's great to see things are going well, & you are having fun. With the YouTube channel you mentioned, if you will be monetizing it (& even possibly if you aren't) & using your drone footage, you will need to get FAA Part 107 certified for commercial drone pilot. If you do not, it leaves you open to some potentially large fines. For the bit of study time, & the $150 or so it takes to write the test, I think it is one of those situations where it is better to be safe than sorry. Also, learning how to read flight charts so you know where you can & can't fly could potentially save your wallet as well. Something to think about as you are working things out. I look forward to more updates on your further wanderings.
