Building remote controlled submarines is hard. Unlike RC boats, cars and planes, there are not thousands of vendors supporting hundreds of thousands of worldwide hobbyists. Like their full-sized brethren, these craft ply the depths in one of the most unforgiving environments on the planet. In "Diving Deep", author Bob Martin brings his extensive experience to bear in an attempt to demystify this amazing hobby, providing an overview of basic information, resources and techniques that the beginning submariner and experienced sub skipper alike will find useful in their building journey. Bob Martin, also known around the world as the RCSubGuy, has been building RC submarines since 1999, and professionally since 2008. He has collaborated with the US Navy and with NASA on various projects, and his scope of work ranges across the entire spectrum of RC submarines, from Steampunk to ROVs, and from scale historical to fantasy.
