Hi @brunopro! I love your video! I actually saw it yesterday when I searched for drone videos on steemit. I wanted to say "First Drone Verification Video!" in my title, but I couldn't because you beat me to it! Very nicely done. :)
I bought the DJI Phantom 3 4k. It's got all of the benefits of the Pro version over the Standard, except for range. I only get 3/4 of a mile instead of 3.2 miles of range. For my purposes, it was worth giving up the range to save about $400.
