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.
HD video starts at the resolution of 1080p as a minimum. For all of these drones, the video is captured at the lower resolution of 720p, even when they claim to have HD cameras. The resolution of still images is always higher than the video. With still photos, the resolution can be as low as 1 megapixel (equal to 1000p) and that resolution is considered HD for still photos.

Most still cameras are 5 megapixels or higher. Therefore, do not be fooled by the claims of HD for a camera when the manufacturer is relying on the resolution for still photos. It is true what they are saying but not the complete story. Having HD resolution for still images does not explain the possibility of also having a lower quality for video-image capture. 
This quadcopter has four available speed modes, so it will be suitable for all levels of flying experience. This drone has amazing features for an affordable price. Along with its features, this a very sleek looking drone with red body accented by dark black propellers. This is a great drone if you are looking to get into FPV drone flying, and capturing decent aerial photos and videos.
If you are a beginner just learning to fly with these cheaper drones, take your time to learn the controls by flying in a safe area that is a wide open space, with no wind, and no obstacles. At first, fly low to the ground until you can maneuver your drone correctly. Practice flying on a single battery charge and then let the drone cool down for ten minutes before flying more.
