Headless mode is another prerequisite feature for your dream device. Also referred to as cheater mode, the headless mode allows you to direct the drone to see any direction it goes as forward. Thus, you do not have to bother about flipping it around and bringing it back to your location at the end of a flight. Once the headless mode has been activated, simply push the joystick in the corresponding direction you want your device to move towards.
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!
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. 

After we’ve taken the drone out to play for a while and jotted down a few notes about how long the battery lasts, we put it on the charger and grab a stopwatch to determine recharge time. Then we take it back out and do a hover test. By flying the drone in the least demanding conditions, we can get a sense of what the maximum flight time is. And finally, we take it out a few more good, hard flights to find out how long the battery lasts (on average) under normal conditions.
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.
For any newcomer interested in diving into the world of drones, look no further. RC Hobby Review has compiled a list of some of the best affordable, and not a single one that follows will be priced higher than one hundred dollars. As beginner it can be a bad idea to jump right into a mid-range or expensive drone, that you could easily crash and total.  There are even affordable cheap drones with camera attachments that we'll look into. We'll break each one down, exposing the pros and cons, and ins and outs so that even complete beginners will be able to find the perfect drone for them. Without further ado, here are is the list.
