Please note that if these drones are flown out of range so that the communication with the drone is lost, the drone can be easily lost as well. A common error is to fly the drone to its height limit and lose communication. If there is any wind, the drone may then do what is called a “fly away.” This is a sad thing for an operator because the drone will fly off to who-knows-where and unless you quickly go chase it; it can disappear forever.
The included 3.7V 650 mAh battery takes about an hour to charge, and will give you up to 9 minutes of flying time. You can extend your flying enjoyment time with the purchase of extra batteries. The controller will give you up to 120m of control range, but limited to 50m when the FPV mode is active. This still allows you to take videos at fairly moderate distances.
The first retail multi-rotor drones were little more than flying toys with limited range and battery power. Their small motors were charged via battery pack, and a basic RF controller moved their rotors to achieve loops, dives, and hovers. But technology has grown in recent years, and today, many people use these types of drones to perform aerobatic stunts and aerial races.
The Hubsan X4 H107C has super stable flight capabilities, gives you approximately 10 minutes of flight time, includes gyro sensitivity that can be adjusted based on your personal preference, and a 0.3MP camera that can record video and take picture paired with a Micro SDHC card. The only feature that seems to exist, and is worth mentioning, is that it can do a 4-way flip, which could be fun and something interesting to add to a video.
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.
Another great feature is you can use your fingertip to chart a flight path. You do this by dragging your finger across the video image from the drone that is shown by its app on your smartphone. Then, the drone will automatically fly the flight path you have chosen. You can also teach the drone to respond to voice commands that you record with your smartphone.
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.
