I've been flying RC for about 45 years. I started out with free flight rubber powered planes, then I progressed into pattern flying when I was about 20 years old. now that I'm older, I like slope soaring, it's nice and relaxing.
Maybe one of them rc planes took a dive and whacked him upside the head.
Maybe he'll come back peaceful and not start bashing. Meh, who am I kidding, he's lost his one and only marble. They say booze will do that to ya.
I was lucky and quit when I lost half my mind
