Dan and Charles,
You each bring up several interesting thoughts.
I agree with Charles, that the 'industry pressure' is on what is commercially, and seasonally, successful. It has always been that way. The "symbiosis" of the hobby and the industry that supports it has always been influenced to some degree by what keeps the hobby profitable enough to support the industry. I started reading the hobby magazines with the September 1949 Air Trails, then discovered Flying Models and Model Airplane News. This "problem" was there, then. Is it any surprise that it is still with us?
I strongly agree, Dan, that those of us who remember the days when there were only one or two RTFs, mostly Cox PT-19s (grin), but also rare, all-metal sparker CL models in the 1940's!
Everything else, until the PDQ and Sterling kits, was printed sheet, you-cut-it, parts, stripwood and (really POOR) plans... But casein glue powder, or even cellulose glue, WAS in SOME of the kits! Once die-crushing became common, the world changed!
Today, we face a slightly different problem: If it isn't a wide enough audience to demand support from "the Majors," it gets harder to find the traditional materials to use today. I even remember when AeroGloss dope was dependable from batch to batch. (20 years ago?)(Thank you, EPA!)
For the survival of "the Industry," we find many firms offering and 'pushing' what we might have considered toys 40 years ago. Ready to play with, disposable once they break, NOT an introduction to the joys of learning building skills, or seeing something WE have MADE actually FLY! (I've run a few Delta Dart programs with local Middle Schools, and the faces of the kids who see what they built actually fly, are magical!) (I'm glad the AMA is back to offering bulk packs to support the Delta Dart concept! They don't push or promote it actively, preferring a more expensive and less handwork system. The other system is more scientific, given, but price may be a limiting factor.)
As our hobby has evolved, we got more and more technically competent. Check out today's FAI FF models! FAI Team Racers! AMA Carrier models with 2.4gHz supplemental functions! Ditto, Scale CL. The growth of electric power. How often do we see these at local flying fields? BUT, nostalgia events are still highly popular, at least among our older troops...
The small-market evolution may have cost us some nation-wide exposure. CLPA may be an example. Stunt News, from Wynn Paul's earliest editions to the present, has been an excellent, focused resource. CLPA would not likely have thrived and survived as well without it. It also is where we CAN find the small manufacturers dedicated to our needs... Mass-media magazines live on advertising, which affects what they offer, cover and study to a large extent. IMHO. The other CL Events have their focused journals, too.
So, Dan and Charles, Best Wishes for what I still call Christmas, and for 2014! Without gently comparing ideas, learning from areas of difference, we could become stagnant. Let's not?
