Just to summarize/comment on drone rules & regulations/possibilities in Norway, from another Norwegian MP owner (since January), quoted from Civil Aviation Authority - Norway. In general you should find our R&R less strict compared to many other countries. No registration nor certificate required for a MP sized drone used for recreation. Here they are:
Top 5 rules:
1: The drone should always be kept within your sight and operated in a mindful and considerate manner. Never fly near accident sites.
2: Never fly closer than 5 km from airports unless you have explicit clearance to do so.
3: Never fly higher than 120 meters off the ground. (Note: You may "climb" most mountains in the fjords as long as the vertical height above ground is less than 120m. Up to the MP ceiling of 500m above Home Point)
4: Never fly over festivals, military facilities or sporting events. Keep a distance of 150 meters. (Note: 50m if subject is individuals/small group of people, cars and buildings outside your control)
5: Be considerate of others privacy. Take note of the rules concerning photos and films of other people.
