Felix,
Rodney's advice is right on, but I just want to say, since I see that was your first post here, don't get discouraged with using this site as a resource. In a couple days you will have 20 responses to your question, checking out a local club will be a common theme in almost all of them. The other thing is when you start asking about planes, radios, engines, etc, everyone will have an opinion, don't get discouraged by that, either. If someone at a local club suggests something, throw it out here and see what the guys think. There's a lot of good advice to be had here. It's a great hobby. Welcome.
