A. The law is a bit murky here in terms of licenses and registering of drones, and as such your best bet is to check local regulations and brush up on the latest requirements from the FAA. In general, you won’t need a license if you’re flying a drone recreationally and the drone weighs under 55 pounds. Anything heavier than that and you might need to register it. If you’re trying to earn money with your drone, you’ll need to be licensed. The FAA is more than willing to fine or even jail those who violate drone rules, so this is definitely not an area you should ignore.

Go for a model which has easy-to-find spare parts even from your local store. It’s highly recommended that you should have at least an extra pair of propellers, apart from the ones already on your drone, including the appropriate tools needed to replace them when they accidentally break down. Furthermore, there should be sufficient protectors available for your quadcopter, so as to prevent damage both to the device and injury to people or property damage in case of any clumsy flights or landings.

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!
If a drone in this category has first-person-view (FPV) capability, you can see what the drone sees. All except one of these drones require a smartphone (not included) to be able to view and record the video. The smartphone is held in a bracket and then it is connected to the controller. Some of these drones can be flown by only using the smartphone with a downloadable app installed that controls the drone. 
The other reason we love this drone is that it’s not super complicated to fly or maintain, so it’s a great choice for beginners and pros alike. Even if you’ve never raced a drone before in your life, you’ll likely be able to learn the ropes with a Draco after just a few hours of practice. Alternatively, if you already have some FPV racing experience under your belt, you’ll feel right at home with this rig.
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.
There are various factors you should take note of when shopping for these particular machines. First, you need to check the control operating system to ensure that it’s easy and manageable to use. Basically, there are 3 main control functions you can choose from which include OPTI, ATTI, and GPS, though they all help in flight-stabilization and assistance they tend to do it in slightly different ways.
