The maximum distance your quadcopter can cover, and where it can be flown, are determined by its overall weight and size, i.e., the weight after all the attachments or payload have been added. The best drones under $100 usually weigh less than 0.55lbs. Thus, they can be flown in most open areas in the US, except in airports and buildings if you have no license.
If you’re looking for quality, the Inspire 2 is the best camera drone you can buy that comes ready to fly out of the box. The next best option is the Phantom 4 Pro and after that, the Mavic Pro. If you’re concerned about video quality, just pick one of the three drones mentioned above (which ever one matches your price point) and you’ll be more than satisfied. There are really no other drones that come close to what these three can do. Some people who shoot videos for a living will buy the Mavic Pro, Phantom 4 Pro, and the Inspire 2, because each of them can be useful for different situations.
Some people will tell you that beginner pilots should cut their teeth on lower-end drones, but in our expert opinion, that’s nonsense. Why? Crappier drones are harder and less reliable to fly, which means that you’re far more likely to crash and destroy them. We think its a smarter idea to start out with a slightly nicer drone with reliable, responsive controls, a decent warranty, and a design that’s easy to repair or upgrade.
Almost all of the models featured here have some safety features. Even the DJI Spark, which isn't built for long-distance flight, includes a GPS and automatic return-to-home functionality. If your control signal is interrupted, or if the battery gets down too low (most drones can only fly for about 25 minutes on a single battery charge), you drone will start to head back to its takeoff point and land.
There are a number of products on the market that are sold as drones, but don't quite fit the bill. Remote-controlled aircraft have been around for ages. (Check out this clip from Magnum, P.I. if you don't believe me, or just want to see Tom Selleck in a bathrobe.) But with the recent surge in popularity, quadcopters that would simply be sold as RC products are now being tagged as drones. These don't include GPS stabilization, return-to-home functionality, and other automated flight modes that make a drone a drone.
Many manufacturers mount cameras inside the body of the drone. This is acceptable for casual photography, but if you want more professional results, consider adding an external camera mount, or gimbal. Gimbals allow you to place your video or still camera in front of the drone body, away from the vibrating motor and rotors. Gimbals can swivel and pivot, providing you with additional control over your imagery.
