Irrespective of the dimensions of your quadcopter, they must not go higher than 400ft above the ground. Likewise, you must always maintain a clear line-of-sight with the machine at all times. You are also expected to adequately inspect your device before each flight session, to ensure its readiness and airworthiness. This is necessary to prevent unnecessary flight accidents.  
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.
The Tello is a brand new quadcopter from the world’s biggest drone company, and it retails for only $99 USD. Technically it’s a joint venture between DJI and Rize, but the important thing is that you’re getting a high-quality product for dirt cheap. A 5 Megapixel camera, 8 dimensional flips, a “throw and go” flight mode, and HD video can all be yours today – learn more by reading our full review here.
Naturally, there are a couple of downsides to a drone being this small – it’s not particularly happy when flying in breezy conditions and the battery life is barely longer than ten minutes. Still, while the body is made of plastic, it’s tough enough so survive some crashes and, in the right conditions, the Tello is an impressively stable and responsive flyer.
This FPV drone focuses more on the actual drone than it does the camera aspects, however, considering you get more features and capabilities. You can use a FPV real time HD live transmission with your mobile device using the FPV WiFi feature, have Headless mode, a low voltage alarm, 360-degree flips, and gravity induction that allows you to fly at all angles and in every direction.
As it is for every gadget out there, a buyer must set realistic expectations when buying a cheap drone (or other devices).  If you set expectations that are too high, chances of being disappointed ultimately are high, and this may ruin your drone flying experience.  Instead of the high standards, expect far less from the device and let it surprise you instead while providing you with so much excitement in the process.  You may consider buying a spare drone also.

The word “drone” has taken on a few different meanings over the years. Some people think of a drone as a bee, others might think of those predator drones that the military uses. The drones that most people talk about today are simply radio controlled aircraft that have some level of autonomous features. A drone can be a plane, a helicopter, a quadcopter, or any combination in-between. Most of the drones sold today are quadcopters. They have 4 rotors and a flight controller that is used to stabilize the lift from the each propeller.
DJI’s latest Zenmuse cam, the X5S, is a mirrorless Micro Four Thirds camera made specifically for aerial photography and cinematography. It shoots in 5.2K at 30 frames per second (or 4K at 60), takes 20.4 megapixel stills, and boasts a ridiculously wide ISO range of 100 – 25,600. As an added bonus, this rig is cradled inside a vibration dampened 3-axis gimbal, so your footage comes out silky smooth no matter how crazily you fly. 
There are various factors you should take note of when shopping for these particular machines. First, you need to check the control operating system to ensure that it’s easy and manageable to use. Basically, there are 3 main control functions you can choose from which include OPTI, ATTI, and GPS, though they all help in flight-stabilization and assistance they tend to do it in slightly different ways.
