Come on everybody. Relax.
No one of us flies a drone since our birth. All of us passed through stages, and many of us never learned to fly a drone. There are hundreds of thousands flying machines, on trees, on roofs, in forests, in rivers, in lakes, and in the sea, and even more in Dji's laboratories, or service companies. And many of the "pilots" who crashed their precious birds, have spent thousands in drones and accessories.
I think he was waitin for a long time for his Mavic to arrive, and wanted this expensive machine to fly out-of-the-box.
Help him if you can, and he will probably learn, as all of us did (not all, ok).
Relax.
