This book explains in simple terms the fundamental principles of flight and the basic aerodynamic factors affecting radio controlled flying models. Neither mathematics or higher physics is required in order to understand how and why model aircraft behave and sometimes misbehave in the way that they do. A little theory can be turned to practical advantage, enhancing model performance and the enjoyment experienced by the model flier. Although the book was written primarily for fliers of conventional radio-controlled models, the principles apply to other aspects of model flying such as free flight, control-line, helicopters and gliders.

This is the latest edition - fully revised and updated - of the standard work on aerodynamic theory, as applied to model flight. Everything is explained in a concise and practical form for those enthusiasts who appreciate that a better understanding of model behavior is the sure path to greater success and enjoyment. The revisions for this new edition reflect the significant developments in model aircraft, including radio frequency (RC) model aircraft and drones, over the last few years. New content including the chapter on aerofoils has been extended to take account of the vast amount of testing carried out recently in the USA at the University of Illinois. A new chapter explains the latest research into the flight of birds and insects which is being applied now to small drones and miniature surveillance aircraft. Older wind tunnel test reports have been replaced with the latest trials and measurements. Full-color photos and line drawings featured throughout. Topics include factors affecting lift and drag, scale effect and the boundary layer, basic model performance problems, reducing induced draft, aspect, ratio, and more.

Airflow examines and describes the many ways in which modellers and practitioners of a wide range of hobbies and sports (even cricket!) can understand and confront, harness and exploit the physical properties of wind and air. The book's admirable breadth and depth offers something not only for students of many science and technical subjects, but also to the hobbyists and disciples of 'alternative energy'. The book will be of particular interest to the increasing number of people who are hooked on the thrill and excitement of sports such as yachting, aeromodelling, ballooning, car racing, parachuting, kite flying, boomerang throwing, hang gliding, soaring in sailplanes and power flying.

This is a simple and easily understood guide to radio control glider flying. No prior knowledge of flying, modelling or radio is required and the advice offered will help the complete beginner to avoid frustrating errors and possible subsequent disillusionment. In this book you will find out how to choose your first model, what kind of radio gear to buy, how to set about building the glider, fitting the radio and linking up the controls, where to get help when learning to fly, how to launch your model and make safe landings, how to fly loops, slow rolls, stalls and spins and how to soar over hills and in thermals.

The standard textbook on aerodynamic theory, as applied to model flight.

Including GPS Waypoint lists and a Place Name Index, this 160-page colour book contains walking routes within the South Downs region. Wire-O spiral binding allows it to lay flat and be folded back on itself without damage. It features: route summary of exertion rating; refreshments rating; time, distance, ascents/descents; and more.

Martin Simons, passionierter Modellflieger und mehrfacher Buchautor zum The-ma Grundlagen des Modellfliegens und der Aerodynamik, beschreibt in seinem Buch "Modellflug-ABC" auf unterhaltsame Weise, warum und wie Modelle flie-gen. Mit seiner klaren und leicht nachvollziehbaren Sprache gelingt es ihm, auch komplexere Themen zu fassen. Sowohl für Einsteiger als auch Fortgeschrittene ist das "Modellfug-ABC" eine wertvolle Hilfe, um zu verstehen, wann und warum Modelle gut fliegen und wie man mit Hilfe dieses Wissens sein eigenes fliegeri-sches Können ausbaut und verfeinert. Aus dem Inhalt: Im "Modellflug-ABC" werden die Grundlagen der Aerodynamik (ohne mathemati-sche Vertiefungen) in Verbindung zum Modellfliegen erklärt, um z.B. die Wirkung von Steuerreaktionen zu verdeutlichen. Welche Auswirkung hat ein symmetri-sches oder ein halbsymmetrisches Tragflächenprofil? Was löst einen Abriss aus und wie fängt man das Modell wieder ab? Was macht ein Modell stabil bzw. wie erreiche ich eine hohe Stabilität? Welche Bedeutung kommt dem Propeller zu? Viele Fragen, die der Modellfliegeralltag aufwirft, beantwortet das "Modellflug-ABC" auf erklärende Weise. Mit dem Ziel, aerodynamische Vorgänge zu kennen und zu verstehen, um Modelle gut einzustellen und zu fliegen. Über 100 Zeichnungen erklären bildlich die im Text beschriebenen Vorgängen und runden die vermittelten Grundlagen des "Modellflug-ABC" ab.
