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.
Any drone is going to be a handful when you’re first learning to fly it, but the makers of drones in this price range largely take the novice pilot into consideration with features that make the UAVs easier to handle. A feature called headless mode (which we cover below) helps you orient the drone, while multiple speeds enable you to start more slowly and gradually go faster as you gain more experience and confidence. Another feature, called one-key landing, can also save the day (and the drone) if your flight goes completely sideways.
While each mode is unique and important to understand, most of them still provide the basic function of flight-stabilization and assistance tool. For instance, OPTI typically features an Optiflow sensor within the drone, which is a downward facing sensor capable of identifying patterns on the ground and helping the machine to maintain a straight position.
Speedy and nimble, the Mavic Air is great fun to use beyond its image-capture abilities – though these are stellar, too. The 1/2.3-inch CMOS sensor sits on a three-axis mechanical gimbal that reduces vibrations and ensures silky smooth footage, with 4K video at 30fps offering plenty of detail. It’s only in low-light that you’ll notice it struggling.
It is important to understand the warning about wind because wind is the most likely cause of serious problems with these drones. The drones in this category do not fly well in the wind because their motors are not strong enough. It is easy to lose them in the wind, so do yourself a favor and do not attempt to fly them, especially up high, if there is even the slightest wind outside. It would be better to fly them indoors if it is a windy day. 
While the Mavic 2 Zoom will still set you back £1,099, that is £250 less than its brother, which makes choosing between the two a tricky choice. While it lacks the one-inch sensor, 10-bit HDR video and adjustable aperture of the Pro, its image quality is still excellent and more than good enough for epic YouTube videos. That spare change could also be put towards a spare battery or a ‘Fly More’ bundle. Whichever way you go, the closely related Mavic 2 Pro and Mavic 2 Zoom are the best all-round drones you can buy right now.
Go for a model which has easy-to-find spare parts even from your local store. It’s highly recommended that you should have at least an extra pair of propellers, apart from the ones already on your drone, including the appropriate tools needed to replace them when they accidentally break down. Furthermore, there should be sufficient protectors available for your quadcopter, so as to prevent damage both to the device and injury to people or property damage in case of any clumsy flights or landings.
Yuneec also has a model with a Micro Four Thirds camera. Its Tornado H920 is a huge drone with six rotors and room to hold three batteries, giving it an unheard of 42-minute flight capability. Its CGO4 camera is essentially a custom version of the Panasonic GH4, a favorite of many a terrestrial videographer. It doesn't record uncompressed video like the Inspire 2, but it's less expensive.
Most still cameras are 5 megapixels or higher. Therefore, do not be fooled by the claims of HD for a camera when the manufacturer is relying on the resolution for still photos. It is true what they are saying but not the complete story. Having HD resolution for still images does not explain the possibility of also having a lower quality for video-image capture.
