As mentioned above, you will crash, and you certainly don't want to go home empty-handed. Having back-up propellers can make or break your day. Extra batteries are also a must. Current battery chemistry limits flight times to somewhere between 5 and 25 minutes for most amateur drones. Having plenty of charged spares means you can fly longer — though flying for more than 30 minutes straight can be fatiguing.
Many autopilot drones come with multiple flight-modes. Common flight-modes seen in autopilot drones include a follow-me mode, sport mode, and one-touch takeoff and landing modes. They all serve different purposes and create different flight experiences. Follow-me modes allow the drone to follow you as you move and keep you in the frame. This enables you to create complex shots. Sport modes all your autopilot drone to go faster and follow targets such as cars or bikes. One-touch takeoff and landing are important flight modes as they allow for smooth landings and takeoffs with the push of a button. This is a great feature for beginners and pros alike.
The DJI Inspire 2 is aimed at professional cinematographers, news organizations, and independent filmmakers. And it's priced as such—its $3,000 MSRP doesn't include a camera. You have the option of adding a 1-inch sensor fixed-lens camera, a Micro Four Thirds interchangeable lens model, or a Super35mm cinema mount with its own proprietary lens system and support for 6K video capture.
Altitude Hold allows a drone to maintain a consistent altitude by analyzing the pressure data further provided by a drone’s barometric pressure sensor. If a drone has an ultrasonic sensor, this is also used with Altitude Hold. This feature ensures even a small drone with camera will be able to hold itself in place while you snap some shots or record a video.
For those looking for a basic done that has FPV camera capabilities that are still pretty decent, but at a fair price, the Hubsan H502S is definitely the way to go. There are minimal features, mostly just the GPS function, which is a nice touch that makes all the difference, and you get up to 12 minutes of flying time on a single charge. You also get Return to Home, Follow Me, one-key control, the whole set. 

Once you have a GoPro hooked up and are ready to go, you can use the TTR Hero application to monitor your distance, altitude, battery level, and more. Follow Me, Landing, Return to Home, and Waypoint Groundstation are the included features. Interestingly enough, Waypoint Groundstation allows support for up to 16 Waypoints that are preset by you before flying, which is pretty neat.
You can pair the Tello with a third-party gamepad controller, but it’s easy enough to fly using the simple, intuitive Tello app. Thanks to its link with DJI (the Tello’s flight controller is made by the drone manufacturer), it’s a great ‘first drone’ for kids or adults looking for a learner model to practice on before moving to a bigger quadcopter like the the DJI Mavic Air.
DJI models currently dominate our top picks, and there's a good reason for that. The company is simply a few steps ahead of its competition right now, and has a product catalog with models at various price points, which take up a good number of the slots in our top ten. It made a huge splash with its iconic Phantom series, and now makes the best small drones we've tested in the form of the Mavic series.

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.
