One thing that many of us who fly Phantoms or similar platforms tend to forget (or may not even know) is that Part 107 is about a lot more than just simple quads like the Phantoms. We have to keep in mind that Part 107 encompasses small multirotors, medium and large multirotors as well as large fixed wing aircraft. Sometimes weather, airport operations, and many other aspects can come into play with larger more complex air-frames. Part 107 "touches" on aspects across a broad range of aircraft and mission possibilities.
