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.
Unfortunately, this one doesn’t come with a controller, which means you’re forced to pilot Tello via virtual joysticks on a smartphone app: a control method that’s notoriously mushy and imprecise. The good news, though, is that Ryze built the drone with third-party peripherals in mind, so if you prefer to fly with physical sticks under your thumbs, you can pick up a GameSir T1d controller and link it to your bird. We think it’s well worth the extra $30 bucks!

After we’ve taken the drone out to play for a while and jotted down a few notes about how long the battery lasts, we put it on the charger and grab a stopwatch to determine recharge time. Then we take it back out and do a hover test. By flying the drone in the least demanding conditions, we can get a sense of what the maximum flight time is. And finally, we take it out a few more good, hard flights to find out how long the battery lasts (on average) under normal conditions.
The Hubsan X4 makes the number four spot on our list. On the other end of the spectrum of affordable drones, the Husban X4 offers what few others in its category can.  The first thing you'll notice is its size, as the Husban X4 is hardly bigger than a standard smart phone. Due to its smaller frame and lighter weight, this tiny drone is best when used indoors, or outside on a calm day with no wind, as it could get carried away by any particularly large gusts.

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.  
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.
