Hey guys, i am totally new to this drone world and I am about to purchase a spark or a mavic air, so both are below 500 grams. I am not sure, I read that Romania (I live here) do not need drones that are under 500 g to be registered, but in USA for example the limit is 250g if I'm not wrong. So i wonder if it should be registered if I'm not planning to go to USA or is 250g the limit in other countries aswell ? Cheers!
