Another big addition is Spark’s obstacle avoidance system. While the ability to sense and avoid objects is usually a feature reserved for larger drones, DJI went ahead and built one into the hull of the Spark. It’s not quite as robust as what you’ll find on the Phantom 4, or even the Mavic Pro, but it still serves its purpose, and helps you avoid crashes.
The word “drone” has taken on a few different meanings over the years. Some people think of a drone as a bee, others might think of those predator drones that the military uses. The drones that most people talk about today are simply radio controlled aircraft that have some level of autonomous features. A drone can be a plane, a helicopter, a quadcopter, or any combination in-between. Most of the drones sold today are quadcopters. They have 4 rotors and a flight controller that is used to stabilize the lift from the each propeller.
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.

You get up to 9 minutes of flight time, have a 640x480p camera, and video capabilities that lack audio as there is no microphone. You can do flips in the air at the touch of a button on the transmitter, and there is a button that lets you share a video on social media instantly. The LED lights located at the center of each propeller and the headlight are pretty useful for flying at night, too.
Flight is smooth on this drone, with an impressive climb and turning rates that meet the demands of even expert fliers. You can count on the stability of the X400W when in windy conditions – the six-axis gyros do a good job maintaining hovering with lateral winds. You can access the FPV stream on your smartphone via a WiFi connection. With the dedicated app, you can activate the camera and record sharp videos and images. It is important to note that the HD 720p camera is primarily for delivering an FPV live stream, rather than shooting pictures and videos. You can also connect this drone with a 3D VR headset if you want to enjoy a 100% immersive FPV flying experience. 
Nevertheless, no matter the dimensions of your craft it’s not permissible for hobbyist drone users to fly their machines over 400ft above the ground, plus you’re required to always maintain a clear line-of-sight with the machine at all times. Furthermore, it’s your duty to carefully inspect the device before each flight session to ensure that it’s airworthy so as to avoid unnecessary accidents. Generally, the best drones under 100 (over 50) weigh less than 0.55lbs, but it’s your duty to ensure that you fly responsibly.
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!
