We test two main things when reviewing drones – their flying performance, and the camera’s video and stills quality. To test flight, we take the drone out to an approved Flying Field like the one in Richmond Park and check its responsiveness, speed, stabilisation, obstacle avoidance and the accuracy of safety features like return-to-home. We also assess the stability and quality of its video feed from its maximum distance and its battery life claims, based on real world use.
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.  
Finally, in the number five spot for this list is the Syma X11. For the drone enthusiasts who may feel a little intimidated by some of the larger drones, the Syma X11 R/C Quadcopter is a perfect alternative. This little R/C unit is 15 x 4 x 8 inches in its dimensions, and weighs just over fifteen ounces. It is a good drone for those who are more comfortable with other R/C units and want something that is easier to control with a price point that is reasonable.
The design of the drone is eye-catching. This drone is small and smooth in nature. The drone was too much low weighted as of 3 ounces and due to these reasons the drone doesn’t need any FAA registration. The drone can be controlled with an app or a remote control or through the scratch programming interface that tello app is free for Android and IOS smartphones. Programming using scratch is kind of difficult but can be obtained by using the tutorials regarding trailer on YouTube or other search engines type video production house. Using the application that comes on with the Ryze tello, the drone allow the user to shoot many video footages on several modes. The thing that should be carried in mind with this drone is there is no GPS with the drone. The footages it gives up is pretty much good but another thing which can call downfall is the battery lifetime- that is not much broader. The purchaser of this drone should be carrying one thing in mind- the drone cannot be set it up to give an air flight on the bad weather as it will crash because of that nature of disasters. The drone that we are talking about is a cheap and mini in size one. So all in all-within the hundred dollar margin; the Ryze Tello is a heck of ask to get it on the users hand.
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.
Most autopilot drones come with high-quality built-in cameras. Some have extremely advanced and professional features like adjustable aperture, zoom in and out, and time lapses. These are great for aerial photographers and their careers. However, drone pilots that love flying for a hobby will enjoy many 1080p HD cameras. The autopilot drones fly so smooth making it easy to capture stunning and clear footage every time.
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. 
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!
To gauge flight performance, we put the drone through a number of tests to see how the manufacturer’s claims hold up. First we take it to a local football field and see how fast it can clear 100 yards, then do some calculations to get an objective reading on speed in miles per hour. After that, we do a similar test to assess ascent and descent speeds, and all the while, we’re also taking notes on how responsive the controls are, how stable the craft is, how far it can go before it’s out of range, and what the overall piloting experience is like compared to other drones.
The Altair Aerial Outlaw Drone is one of the best GPS drones around and the absolute best that you can find for under $300. Thanks to the stabilization features in GPS flight mode, this drone will keep itself hovering in midair at whatever place you choose for it to go, making it easy to line up the perfect shot for your photo or video camera. It also has a 1000 meter flight range and a flight time of nearly 20 minutes, which is great for aerial photographers who need time for a longer shoot. If you want high definition, pro-quality photography at a price that won’t break the bank, the Outlaw is the choice for you!
There is an altitude hold function that allows you to take aerial shots by releasing the throttle.  Once the throttle is released, the drone hovers in place and take the shot. As a beginner, the headless mode will help you to understand the capabilities of the drone better. Once you’ve gotten conversant with the features, you can do aerial tricks and flips with the drone.
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.
