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 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.

This is the latest edition - fully revised and updated - of the standard textbook 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 behaviour is the sure path to greater success and enjoyment, whether just for fun or in competition. The revisions for this new edition reflect the significant developments in model aircraft during the last few years, and include brand new data: - The chapter on aerofoils has been rewritten to take account of the vast amount of testing carried out recently in the USA by the University of Illinois. - A brand new chapter explains the latest research into the flight of birds and insects and how it is applied to small drones and model-sized surveillance aircraft. - Older wind tunnel test reports all replaced with the latest trials and measurements.

This book summarizes work done by the authors under theEsprit Tool Use project (1985-1990), at GMD in Karlsruhe andat Berlin University of Technology. It provides acomprehensive description of the generic developmentlanguage Deva designed by the authors. Much of the researchreported in this monograph is inspired by the work of MichelSintzoff on formal program development; he contributed anenlightening Foreword. Deva is essentially a typed functional language with certaindeduction rules. The difference with ordinary languages is,of course, the application domain: the types serve here toexpress propositions such as specifications or programs,rather than just data classes. Its practical applicabilitywas tested on several non-trivial case studies. The wholebook is written using the DVWEB system, a WEB for Deva,beeing implemented at the Berlin University of Technology.
