Book excerpt: Building scale model boats that can sail under their own power is a challenging and rewarding hobby requiring varied skills from woodworking to painting to wiring electrical components. This book details everything you need to know to get started: from the tools, materials and equipment required to motors, servos, propellers and remote controls. There are step-by-step guides to the more challenging procedures. There are details on the different types of kits available and how to choose one. Advice is given on glues, fillers, making silicon moulds, and finishes such as painting, decals and weathering. Finally, there is the building of an off-the-shelf kit for the steam yacht Komet and scratch-built RNLI Lifeboat The Torbay Severn class lifeboat.
