Yes, if you want to do anything that is useful with a drone you are supposed to have the 107 license. I have had a private pilot license for over 30 years, so all I had to do was pass a very easy test online and get a signature in my logbook from a flight instructor.
I’m looking at trying a discovery flight and see if I have it in me and the interest to learn how to fly a plane.
The 107 test wasn’t hard since I bought a reputable online training program and did the test exercises enough times.
My test took maybe 10 minutes for 60 questions. I drilled practice exams two or three times a day for a week prior. Came out with a 92.
A fair amount of the test was common sense.
