Before settling for any of the best drones under $100, ensure that the spare parts are easily accessible. You will definitely require an extra pair of propellers, other than the inbuilt pair, as well as essential tools to fix the spare when the inbuilt gets bad. You will also need sufficient protectors for your quadcopter – they come handy in protecting your drone from getting damaged, damaging properties, or injuring people during clumsy flights and landings. An extra pair of batteries is also a good buy, especially in instances where the drone is expected to serve longer than usual. The batteries of most drones under $100 are usually sold in six-pack sets, alongside a charger. With this set, you can get an average flight time of 5-10 minutes before recharging them or switching them with charged ones. It is important to note that the battery time depends on the blade protectors and the presence or absence of a camera.  
If you’re looking for quality, the Inspire 2 is the best camera drone you can buy that comes ready to fly out of the box. The next best option is the Phantom 4 Pro and after that, the Mavic Pro. If you’re concerned about video quality, just pick one of the three drones mentioned above (which ever one matches your price point) and you’ll be more than satisfied. There are really no other drones that come close to what these three can do. Some people who shoot videos for a living will buy the Mavic Pro, Phantom 4 Pro, and the Inspire 2, because each of them can be useful for different situations.
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.
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 Tello is a brand new quadcopter from the world’s biggest drone company, and it retails for only $99 USD. Technically it’s a joint venture between DJI and Rize, but the important thing is that you’re getting a high-quality product for dirt cheap. A 5 Megapixel camera, 8 dimensional flips, a “throw and go” flight mode, and HD video can all be yours today – learn more by reading our full review here.
Another one of the great drone on this list with the beginner in mind, the UDI 818A HD Drone is electric powered, radio controlled, and equipped with six gyroscopes for stabilization. Although it can take a decent beating, it is recommended that this drone not be flown above asphalt or concrete, as it is still made of plastic, and can break if improperly used.
