You probably already know this, but if you have a pilot’s certificate, any grade, and a current Flight Review, you can get a Remote Pilot Certificate with Small UAS Rating which, among other things would allow commercial operation of drones under 55 lbs. It’s an IACRA process, requires a pretty simple online quiz, and is free. The key advantage of flying under Part 107, which might be occasionally useful for even the casual drone operator, is that many of the restrictions that would apply if flying it as a model aircraft are FAA waiverable through a fairly efficient process.
It didn’t require a waiver, but I recently shot some Mavic Pro 2 footage of a few homes and properties for a buddy who’s a real estate agent. Even though I didn’t charge him anything, that would be illegal without a Remote Pilot Certificate. It was fun though, and he liked the footage and editing so much that next time I’m going to charge him.
