FPV

First Person View (FPV) drones, such as the dji Avata series and dji FPV series, provide a "first person" or "pilot eye view" when flying.  Rather than looking at the drone from the ground, the remote pilots use goggles, or a display on the controller, to see a view similar to what they would see if they were in the drone rather than on the ground.

Wikipedia

Wikipedia has a great page on First-person view (radio control) drones.

On that page, they point out that:

"In the United States, FPV operations and unmanned aircraft generally may be subject to regulation by the following entities:  Federal Aviation Administration, Federal Communications Commission, National Park Service, State and Local Governments, and the Academy of Model Aeronautics"

You can fly an FPV drone under part 107 rules or under the recreational exemption 49 USC 44809.  FPV drones are subject to all of the regulations that apply to non-FPV drones concerning air space authorization, restrictions on where you can fly, how high you can fly, where you can take off and land, the need for a Visual Observer (VO), and the need to stay within Visual Line Of Sight (VLOS).

In Clark County (at least in Clark County Parks), "Smaller drones designed for racing and/or maneuvers will require a special use permit available through the Parks and Recreation Department."  If flying outside of a Clark County park, but still within Clark County (which contains the cities of North Las Vegas, Las Vegas, and Henderson), this county ordinance may still apply.
