We test two main things when reviewing drones – their flying performance, and the camera’s video and stills quality. To test flight, we take the drone out to an approved Flying Field like the one in Richmond Park and check its responsiveness, speed, stabilisation, obstacle avoidance and the accuracy of safety features like return-to-home. We also assess the stability and quality of its video feed from its maximum distance and its battery life claims, based on real world use.
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.
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.
