Wow this looks very nice, when I see these pictures I think about buying a drone on my own, but on the other hand they put pretty bad restrictions on drones here in Austrian and you need a flight permission from a lot of different institutions, so it is not fun anymore and more administration than fun,
Oh, flight restrictions are always a painful topic: (In Austria, you need a permit even if you plan to fly somewhere over the wilderness? Oh, this bureaucracy... In Russia, it's easier now, you need to get permission for flights only in certain places, most often these places are in cities.
Yes for drones more than 250 Gramms you need a general flight permission from Austro Controll (Fligh Controll in Austria) aditionally you need a permission for the regions you want to fly. You are not allowed to fly in nature reserves and protected areas and if you want to fly over populated areas there are also a lot of restrictions.
So there are only a few places where you can fly with a drone and these are getting fewer and fewer.
Yeah, it's not very fun. Maybe later, when drones are more widespread, the laws will soften.
