The flying of radio controlled gliders and sailplanes has become a major branch of the aeromodelling hobby over the last thirty years. Today, while the traditional slope soaring and tow-launched radio control gliders are as popular as ever, a huge variety of powerless flying models can be seen on the club flying site and a bewildering range of plans, kits and accessories is available. This is the book which explains it all; more than a technical reference book, the author explains in a readable and accessible style just how the hobby has developed: the great scope of radio control soaring; design, traditional construction and flying basics; constructing with the same hi-tech materials as full size gliders; acrobatic sailplanes; sport and contest flying; flying of unpowered scale models of the latest jet fighters; detecting and utilising slope and thermal lift; high performance competitive thermal soaring.
