It’s already there, you just have to build one that isn’t shite. A good controller and good software (there’s great open source software out there like CleanFlight) make all the difference in the world.

The real question is - when you flew the DJI phantom for the review you were writing for pay on this commercial web site - who was the licensed pilot and who was the spotter as required in the FAA part 33 exemption you must have filed in order to do it legally?
