RE: Why the AMA is not growing...........
There are people spending big bucks to develop better small electric motors for various applications. Also people spending big bucks to develop cheaper, lighter, smaller, safer, more powerful power sources for electrics. There are a few dollars being spent to develop better IC engines. My guess is that ten years from now my IC engine on the flying field will be a curiosity. I may not even be allowed to fire it up.
What is happening is that model aviation is becoming more populist and less elitist. It is growing fairly rapidly and the growth is happening outside the AMA. We are, in fact, an elitist organization. We are faced with the challenge of becoming populist while retaining our elitist virtues (whatever you think they are.)
