I think SPS has it nailed.
I am competition oriented. I saw Bill Sheets F3A ship at the club field, I asked if that was the new style Pattern ship, he asked if I was the guy with the Kaos, he said I could fly it at a contest, and a few months later I was a Pattern pilot.
My kids don't like competition, they like the models, the socialization. They all have won some event, flown a bunch of them, but they don't stick with it. Different desires.
