This is the book that started it all, I believe. I mean scale model size turbo jet engines. With this book you can build your own FD3, the book contains complete parts and GA drawings for FD3 engine and detailed instruction on construction and operations along with easy to follow yet thorough treatement of the design process. FD3/64 is 265 mm x D 110 mm jet engine capable of 24 N of thrust. Constructed from easily available materials with simple tools (a metal turning lathe is necessary). An especially atractive feature is that this is a real from-scratch approach.
