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.
For those looking for a basic done that has FPV camera capabilities that are still pretty decent, but at a fair price, the Hubsan H502S is definitely the way to go. There are minimal features, mostly just the GPS function, which is a nice touch that makes all the difference, and you get up to 12 minutes of flying time on a single charge. You also get Return to Home, Follow Me, one-key control, the whole set.
The Altair Aerial Outlaw Drone is one of the best GPS drones around and the absolute best that you can find for under $300. Thanks to the stabilization features in GPS flight mode, this drone will keep itself hovering in midair at whatever place you choose for it to go, making it easy to line up the perfect shot for your photo or video camera. It also has a 1000 meter flight range and a flight time of nearly 20 minutes, which is great for aerial photographers who need time for a longer shoot. If you want high definition, pro-quality photography at a price that won’t break the bank, the Outlaw is the choice for you!
Often repainted and re-branded (sometimes at a much higher price) the Syma x5c is positioned at a competitive price for what you get in the box. For about $50+ shipping depending on where you order, you get the quadcopter itself, a transmitter, one battery, and a charger. Extra batteries are inexpensive and you’ll certainly want them if you plan to fly for longer than 6 minutes, but they charge quickly, which is nice. At 9 and a half inches diagonally motor to motor, its not small enough to fly indoors.
Any drone is going to be a handful when you’re first learning to fly it, but the makers of drones in this price range largely take the novice pilot into consideration with features that make the UAVs easier to handle. A feature called headless mode (which we cover below) helps you orient the drone, while multiple speeds enable you to start more slowly and gradually go faster as you gain more experience and confidence. Another feature, called one-key landing, can also save the day (and the drone) if your flight goes completely sideways.
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.
