This is the drone you start with if you're worried about crashing. Thanks to flexible plastic and propellor protectors, you could drop this on the ground or fly into a wall without too much damage. It has a camera if you are just getting into drone photography, but we prefer this model as a starter quadcopter. Beware: when it has low battery, the drone tends to lose connection with the controller. This could become tragic if you've flown the drone over water.
If a drone in this category has first-person-view (FPV) capability, you can see what the drone sees. All except one of these drones require a smartphone (not included) to be able to view and record the video. The smartphone is held in a bracket and then it is connected to the controller. Some of these drones can be flown by only using the smartphone with a downloadable app installed that controls the drone. 
For example, OPTI has a built-in Optiflow Sensor (a downward facing sensor), which functions by picking out the patterns on the ground to ensure that the drone maintains a straight position.  ATTI, conversely, works a bit differently. With the ATTI, the drone employs other techniques apart from the external sensors to keep the drone in the right orientation and altitude. Thus, the drone can hover in place, or drift slightly around with the wind serving as a push. You will also find a GPS in some drones, and they help the drone to maintain coordinated and precise flights and landings. 

A. The law is a bit murky here in terms of licenses and registering of drones, and as such your best bet is to check local regulations and brush up on the latest requirements from the FAA. In general, you won’t need a license if you’re flying a drone recreationally and the drone weighs under 55 pounds. Anything heavier than that and you might need to register it. If you’re trying to earn money with your drone, you’ll need to be licensed. The FAA is more than willing to fine or even jail those who violate drone rules, so this is definitely not an area you should ignore.
Generally speaking, drones that cost less than $100 bucks aren’t worth your time. They’re flimsy, they lack advanced features, and they’re almost always squirrely as hell in the air. But Tello is different. Despite the fact that it retails for only $99, it boasts a boatload of high-end features and functionality. Under the hood you’ll find a 14-core Intel vision processing chip, flight stabilization tech from DJI, a 5 megapixel camera capable of shooting 720p HD video, and a battery that gets you 13 minutes of flight time.
