This is a large format book giving detailed scaled drawings of various light aircraft components such as control surface hinge assemblies, tail wheel mounts, strut fittings, engine mounts, axles, control linkages, and many others. Then intention is not that you would copy or build these exact components (although the drawings are sufficient to do so), but instead that you can see and study the standards of how such components are designed and built, so that you can apply those standards when designing for your own specific needs. Additional sections include practical wing design, and conversion & engineering tables to assist in your specific design applications.
