The book continues a number of thematic publications in the “Amateur Radio” series. The titles of these books begin with the words “500 circuits...” with clarifying titles “Receivers”, “Power Supplies”, “Radio Stations and Transceivers”... This book presents circuit designs for REMOTE CONTROL MODELS. The brief description provided is quite enough for you to independently make the design you like. Making models in itself is a very exciting activity. But the greatest interest is in the production of controllable models. They have long been widespread in Japan, the USA and Europe. And in Russia, modeling is taking its first steps: amateur clubs are being created, stores selling ready-made kits (model and control system) are appearing... However, branded products are not cheap, and it’s hard to deny yourself the pleasure of making some elements and even the entire kit yourself! This book is unique. It will introduce the reader to the principles of operation and practical circuitry. All considered designs are made on a modern element base, the circuits are accompanied by detailed descriptions, drawings of printed circuit boards, recommendations for assembly and configuration. The book is designed for both beginners and “advanced” radio amateurs who are interested in practical radio electronics.
