I started on the Internet and quickly found that the best place to find information about the subject is forums. Being from Denmark, I used the Scandinavian forum a lot in my research. But there are many English spoken forums as well and if you do a Google search you might find that there is one in your country too. Everybody on these forums share your passion for helicopters and are always glad to be able to share their knowledge and help others along the way. One general rule though is to have a good look around and search on the forum before you ask. In many cases somebody else will already have asked the question - but if you don't find it don't be afraid to ask!
