The Library page has been updated to include links to Aerofred and Outerzone (both have free downloads of aircraft plans some of which also have build articles) and RC Bookcase and RC Library (good sources for vintage RC magazines, catalogues and books).
If anyone knows of other good sources (preferably free) for information related to any aspect of RC aircraft or heli modelling, building or researching on the internet would you please add it to the club website either by appending a comment to this post or sending me an email.
