just about everything you could ever think of needing for your aeromodeling
hobby was made in China and sold here at a dirt-cheap price, resourcefulness
and creativity, combined with some mechanical skill, was needed by most
hobbyists. Even those who could afford to buy everything they needed
were not always able to find it already made and hanging on the hobby
shop wall. Improvisation was the order of the day. These monthly "Sketchbook"
features are a prime example of what I'm writing about. Having read
through many of the ideas in many issues of American Modeler, I am a
little dubious about the practicality of some of them.
This page has links to every edition of
Sketchbook that I have so far.
