For a couple of years, I made a sort-of living writing the instruction manuals for model airplane kits and ARF models. Included flying toys, Czech import competition free flight rubber powered aircraft, even a couple of cars and boats, and a few old-school balsa built-up models. Worked for a few mfg's including small garage kit makers, importers of Chinese kits/ARF's, to include Hobby People which is one of the largest.
Having considerable ability in this rare and specialized pursuit (forgive the ego trip), and thus imagining myself wealthy and happy doing this kind of work as a career, I diligently approached almost every manufacturer, reseller and importer of model airplanes that I could find. I explained how the instructions were the only communication their company would ever have with their customers, how the instructions were the de facto difference between a good and bad customer experience, etc. etc. etc. ad nauseam. Most of all, I explained how a good set of instructions built repeat business, got the product better magazine reviews, was the biggest improvement they could make over the lifetime of their product, and it worked out to being the lest expensive of any upgrade they could do. Some of you may understand that good instructions can make a mediocre product into an upscale or higher quality product, with no change in the actual physical product. (The fact that there are fewer and fewer model builders who know how to build properly is a separate, yet equally disturbing concept)
The old-school USA balsa garage kit manufacturer (MM Glidertech, great designer and true quality wood kits), the flying toys manufacturer, and Hobby People (a well-run business that cared about the customer experience with imported Chinese models) were the ones who placed a value on having a really good instruciton manual. ALL of the "broker" type Chinese importers or US retail divisions of Chinese or Taiwan manufacturers were not concerned enough to spend money on a top quality manual (forgive the ego again). They saved a few hundred or a thousand bucks by hitting the "translate" button in Google or Babelfish or whatever, and so you got instructions that say "glue the dog to the bumper, being cognizant to kettle the floozy".
