Basic controls are required for a normal, just-for-fun flight, but when you are taking part in a race with world-class drone pilots as your competitors, you need to master some advanced level skills as well.
Fine tuning your drone to keep it stable when taking off and flying in mid-air is also a very important step. How to change the altitude, how to fly through the trees and how to avoid obstacles or even collide with small objects during flight and getting back on the track again are some of the things you need to learn.
