On the other hand, ATTI is a partially different tool, whereby the quadcopter uses other techniques and not necessarily external sensors to firmly hold the drone in correct altitude and orientation. ATTI allows the drone to hover in place, as well as to gently drift around while being pushed by the wind. Some drones also have GPS which offers great precision and coordination during flight.
This drone seriously has it all. It’s powerful. It’s portable. It can dodge obstacles autonomously. And to top it all off, it has a camera that produces some of the best-looking aerial imagery we’ve ever seen. Truth be told, you can get a lot of these features in the original (and still very good) Mavic Pro, but the Mavic 2 Pro just does everything better.
For example, OPTI has a built-in Optiflow Sensor (a downward facing sensor), which functions by picking out the patterns on the ground to ensure that the drone maintains a straight position. ATTI, conversely, works a bit differently. With the ATTI, the drone employs other techniques apart from the external sensors to keep the drone in the right orientation and altitude. Thus, the drone can hover in place, or drift slightly around with the wind serving as a push. You will also find a GPS in some drones, and they help the drone to maintain coordinated and precise flights and landings.
There’s one other type of beginner that isn’t looking for either of those things. Some beginners just want a drone to take pictures and videos with. They need whatever drone they get to be easy to fly and have decent specs, but not break the bank. For those people, the DJI Spark is going to be the best option. There’s no reason to buy the other two drones I mentioned if you want to shoot videos and take pictures. The Spark is actually easier to fly than the Bugs 3 and Mambo FPV, so you don’t have to worry as much about the flying part.
Aside from its tiny and hyper-portable design, the Spark’s biggest feature is arguably its plethora of intelligent flying modes. In addition to DJI’s standard stuff, the Spark sports a handful of brand-new modes, including Rocket, Dronie, Circle, and Helix (more on those in a moment). The drone also comes with gesture recognition abilities, which allow it to be operated without a smartphone or controller.
The controller has an LCD screen that displays important information such as battery life, range, and trim adjustments. The acceleration power is also displayed in percentage form. The controller also has a return to home button. Press this and the drone flies back to you. This is not a feature commonly found on a drone at this price point. The 2MP camera on the F181 is of 720p resolution and can take images at a 1280 x 720 resolution.
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.
