Once you have a GoPro hooked up and are ready to go, you can use the TTR Hero application to monitor your distance, altitude, battery level, and more. Follow Me, Landing, Return to Home, and Waypoint Groundstation are the included features. Interestingly enough, Waypoint Groundstation allows support for up to 16 Waypoints that are preset by you before flying, which is pretty neat.
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.
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.
The most recent variant, the cx10c, is another small improvement over the other two. Again, it only adds one feature, but this time its a little bit more substantial, this time, they’ve added a camera. With a micro sd card you can watch videos of your flights from the perspective of the drone. It may not be a great camera, its not even a good camera, the footage is mediocre and would never compare even slightly to a high end multirotor, but for the price ($25) and the size (roughly the same as before) its amazing that it includes one.
Here is an ultimate drone that can take aerial images and footages of professional quality. There is an inbuilt FPV function in the HD camera, with a 120-degree wide angle lens that can be adjusted to take excellent and crystal-clear aerial images from all angles. You can connect the FPV system to your phone via a WiFi real-time transmission, and access the drone’s view from your phone’s screen while sharing with family and friends.
