I don't know too many people who are content with only 2 parkflyers & are actively involved on an RC flight forum, hehe.
Not saying there aren't any, but those that don't fly much or only have 1 or 2 planes probably don't have the need/drive to learn much more or ask too many questions. Clearly the majority of active forum members will be deeper into the hobby and with that comes more planes, faster planes, bigger planes... and more money.
I actually expected the 20-29 age group to be higher because less of us have wives/children/houses to use up all the freetime and income.
About the forum stuff BEFORE buying/flying a plane. You're absolutely correct, I have people ask me questions all the time when I'm out flying at a park. I can't possibly give them even a fraction of the knowledge they need to successfully fly a plane. I'm sure a couple have tried to get a cheap RTF going, but I doubt any went online to learn more, despite what I recommended.
Anyhow, getting off topic now. I'm just surprised at the results thus far, but it really does make sense to me after thinking about it.
