Book updated May 2025. This training book has been developed from the ground up for beginners who know little about electric power RC technology. As part of our RC Technology Self-Paced Training Series, this book gives an introduction to ONROAD EP RACECAR architecture. The primary goal of this book is to explain the various electric powered RC technical concepts (including brushed and brushless power as well as AM and 2.4G radio) in very simple language. A systematic troubleshooting guide is also included. We believe that this book and its support materials have everything you need for an informative, interesting, challenging and entertaining RC educational experience.
