RE: Thinking of starting this hobby, in Sweden
Hello Pierre, welcome to RCUniverse!
The two best steps you could take right now are to meet the people who fly near you, and get a simulator. There are several good simulators on the market that are relatively cheap (Under $50 USD)
The simulator will help you to learn, and the guys at your field will be able to help you choose which plane/engine/radio they are most familliar with. Next time you see them flying, just stop in and say hello. They will be happy to talk to you about the hobby.
