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.  
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 FPV stream is transmitted over Wifi, and is viewed on your smartphone using an installed app. The camera can be activated using the app to record photos and videos. The HD 720p camera has decent quality, and provides sharp images and videos. However, the main purpose of the camera is not for taking pictures, but to provide a FPV live stream. This drone is also compatible with a 3D VR headset to give you a truly immersive FPV flying experience.
There is a wide variety of full-featured drones now available for less than $100. While you won’t get the range or feature set of a more expensive option, an inexpensive drone is the perfect choice if you’re just starting out. It’s generally easier to operate than its pricier counterparts yet sturdy enough to withstand a variety of novice pilot mishaps. The majority also pack features that you might be surprised to find at this price point.
The quadcopter is only about 3.5’’ measured diagonally motor to motor making it one of the smallest drones on the market. Even in that small chassis, Cheerson managed to fit a 100mah battery. While that may not sound impressive, it delivers solid flight time, keeping you in the air for somewhere between 4 and 8 minutes depending on how hard you fly it.
Even if you have no good reason to justify buying one, you have to admit that drones are cool. Some are glorified tech toys, but most models we highlight here are fit for use in imaging and cinematic applications small and large. If you think you can use a flying camera in your next project, there's some good news—the tech has come a long way in a very short time. There are models on the market now that put earlier copters to shame in terms of video quality and stabilization.
The quality of the video captured by these drones is fine for flying them and it is good enough to post on social media. However, the video quality is not HD. This can easily be seen when playing the recorded video on a screen that is larger, like the typical laptop screen that is 1080p. Video that is 720p will look pixelated and fuzzy when viewed at full-screen size on a screen that is 1080p high. 
The Altair AA108 is durably built and will not break easily. You can count on a solid flight time of around 10 minutes, a bit less when you’re running it FPV. However the 720p camera really works well and connects to your phone through WiFi. It’s easy to fly because it has 3 flight modes, 1 beginner, 2 intermediate and 3 advanced mode. It also has Altitude Hold which allows you to take your thumb off the control and the drone holds it’s own altitude, making it very stable because it’s not bouncing up and down as you try to maintain altitude!
