You lucky ...
In Belgium you need to get a medical exam, then you need to take an exam concerning the law, navigation, weather and also flying skills. If all this is then passed you receive your drone pilot licence. When you have your licence your multicopter needs to be also licensed. So if the bird does not have enough security systems this license is refused.
If all is OK the you may fly until 90m max height ... pfffffffffffffffff
Amateurs may only fly until 30m height and only on a designated place for RC flying. So flying in your own backyard will not be allowed. **** ...
