Most drones are pretty easy to fly, but the controls will be slightly different depending on what kind of drone you get. Camera drones are the easiest drones to fly, while toy drones can be harder (because of their lack of sensors and flying aids). To fly a camera drone, people usually use a controller with their smartphone attached to it. The smartphone will let you see a live video feed and all of the most important flight data you need. Some drones like the DJI Mavic Pro, DJI Spark, and Yuneec breeze allow you to fly just using your smartphone.
All drones that have 4 rotors (quadcopters) will have 4 main controls spread between two joysticks, Sometimes, the joysticks can have custom mappings, but most will be set with the throttle and yaw (move up/down and rotate left/right ) on the left joystick. The Right joystick will then control the forward/backward movement and left/right movement.
