I am new at flying a drone so my opinion is based on very little experience. Apart from getting comfortable with the directional controls, it seems like there are two other challenges in flying a drone. One is developing the skills and courage to fly it far away, still keeping it in sight at all times. The other is the ability to control the drone well enough to fly close to obstacles like trees and buildings.
Today I tried the flying far away part. This is an edited video of the flight.
