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 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.  

If a drone in this category has first-person-view (FPV) capability, you can see what the drone sees. All except one of these drones require a smartphone (not included) to be able to view and record the video. The smartphone is held in a bracket and then it is connected to the controller. Some of these drones can be flown by only using the smartphone with a downloadable app installed that controls the drone. 

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.

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!
