A neighbor of mine just bough his son a stryker and was asking my advise on where to fly it etc. I told him to come with me down to my clubs field, I would introduce them around and get one of our many instructors involved. This went to deaf ears as he had too much pride to allow his son to see him as a newbie. It was a very windy day and he suggested that they would head out to the local soccer fields and "put her in the sky" well I explained to him that his aircraft was approx 1/5th scale or smaller. to use that calculation on the wind and think about it. If it is blowing 20 mph that would be the same as 100mph winds, I asked him if he would climb into a 747 that was about to take off in 100mph winds? He thought about it and declined to fly.

Sometimes you just have to figure out a language that you audience understands.
