Under construction

Originally developed for military and special operation applications.
Now used in a small but growing number of civil applications, such as policing and firefighting, and nonmilitary security work, such as surveillance of pipelines, Amazon delivery, Real estate arial photos.
Hobby Drones have become popular around 2015 and fall into 3 categories:

  • NANO / MICRO (Toy) Quadcopter Drones - They fit in the palm of your hand and cost less than $70. Some have built-in cameras.
  • Hobby quadcopter drones - $70-$500 - They are easier to control due to better on-board sensors and more stable in flight than smaller quadcopter drones because of their larger size. Typically these cool new drones come with a built-in camera or an installed mount that is compatible with the most popular brands of small portable cameras
  • Professional Quadcopter Drones - Most include an HD on board camera. Well suited for taking aerial photography with longer flight times, typically around 30 minutes or so. Prices start at around $500.00 and can go into the thousands. Most new Professional drones include: Waypoint mission planning, Follow me mode, Return home function and Optical Flow Sensors for indoor flying along with real time telemetry monitoring.

I couldn't find any reviews or summaries which answered questions about features I was intersted in.

  • Is the user control via a controller or yoursmart phone or tablet?
  • Does the video show up on your control device or does it just download on a chip in the drone.
  • Or do you have a separate controller to fly the device which sends the video to your smartphone or tablet via bluetooth.
  • Do you need special goggles for First Person View (FPV)
  • What is the weight. Drones over 0.55 pounds must be registered with the FCC $11.
