It's clear from the shorter battery charge time, short flying time, and flying distance of forty meters or less, that the X11 is a drone built for smaller purposes. The forty-minute charge time is perhaps the X11's most convenient feature, as it makes it one of the drones with the shortest charge times, while also able to live up to a comparable battery life of models like the X5C and UDI 818A.

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.
The biggest downside to the Syma X11 is that it comes with no camera attachment. This is a good drone for beginners only interested in flying for fun and seeing what drones have to offer, but any hobbyist interested in taking pictures or video will want to keep looking. However those looking for an affordable drone, this one might be just what you are looking for.
And the best part? Parrot also gives you the option of piloting via smartphone or with a dedicated dual-joystick controller. The Flypad, as it’s called, is sold separately for $40 bucks, but it might be worth the extra dough if you don’t have a spare smartphone lying around and don’t feel like handing your kid your brand new iPhone every time he/she feels like flying.
You can pair the Tello with a third-party gamepad controller, but it’s easy enough to fly using the simple, intuitive Tello app. Thanks to its link with DJI (the Tello’s flight controller is made by the drone manufacturer), it’s a great ‘first drone’ for kids or adults looking for a learner model to practice on before moving to a bigger quadcopter like the the DJI Mavic Air.
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.
The weight of the Holy Stone is about 14.1 ounces and a dimension of 12 x 12 inches. The range of the transmitter is 330 feet, with the ability to stay up to seven or ten minutes of in air at a go. Despite the weight, it is still in line with the FAA’s regulations, and you will not require a license. The drone has a slow rotation around the vertical axis, i.e., yawn, although you will still do some tricks conveniently with it. The resolution of the photos taken by the drone is not so bad. However, there is reduced stabilization during flight times. 
Another one of the great drone on this list with the beginner in mind, the UDI 818A HD Drone is electric powered, radio controlled, and equipped with six gyroscopes for stabilization. Although it can take a decent beating, it is recommended that this drone not be flown above asphalt or concrete, as it is still made of plastic, and can break if improperly used.
