The 'ShipCraft' series provides in-depth information about building and modifying model kits of famous warship types. Lavishly illustrated, each book takes the modeler through a brief history of the subject class, using scale plans to highlight differences between sisterships and changes in their appearance over their careers, then moves to an extensive photographic survey of either a high-quality model or a surviving example of the ship. Hints on building the model, and on modifying and improving the basic kit, are followed by a section on paint schemes and camouflage, featuring numerous color profiles and highly-detailed line drawings. The strengths and weaknesses of available kits of the ships are reviewed, and the book concludes with a section on research references - books, monographs, large-scale plans and relevant websites. This volume features the King George V class battleships, the most modern Royal Navy battleships of WW2 and a very popular modeling subject. The King George V herself helped sink the Bismarck, and the Prince of Wales was famously sunk by Japanese aircraft in the Far East. Ships of this class served throughout the war in many theatres, and their changes of armament and color scheme during this time offer many opportunities to the ship modeler to modify basic kits to show ships at different periods in their lives.

Flying a model helicopter is a challenge almost as difficult as flying a real one, and the wise modeller will seek the fullest advice on all the possible variations and handling techniques before embarking on attempts to fly. They will find all the advice they need here - in Dave Day's classic book, now revised and updated for the first decade of the 21st century. The continuing development of radio controlled model helicopters over the years since this book was originally published has led to great sophistication in the hobby. This in turn has produced a situation where the actual flying of a correctly set up model with the latest radio equipment is considerably easier. Despite this, the process of learning to fly has not really changed a great deal, while the setting-up process has become increasingly complex. Both must be learned and developed by the individual with practice and perseverance. In this book Dave Day, who had the forethought to record his early experiences as they happened, and who has continued the process as his skills developed, sets out a step-by-step programme from the first exercises through to advanced aerobatics and beyond. These are accompanied by comments on a typical model, its requirements and its setting-up which will be of interest and value to all model helicopter flyers irrespective of their skills.

This volume contains full-size plans for eight flying models powered by carbon dioxide bulbs. It is part of a series of books of scaled model plans designed with photocopying in mind. The plans can also be enlarged if required.
