All great advice. The only thing I would add again would be to get someone else to train your son. I taught both my son and daughter, sometimes with it being dad on the end of the buddy cord the kids would not take some things seriously. Completely normal I think with Dad/child training relationships. Dad's also can be more demanding then they would be for a stranger. If there is someone you trust at the field to train your son and will do it in a fun way then I would give that idea some thought. If there isn't then train him yourself with all the great advice already given. Good luck
Mikecam,
I hear you and your logic is sound, however, this is also my bonding time with my son. I am making a concerted effort to be "neutral", but if need be I will hand him off to a friend if our father/son relationship gets in the way of instructor/student. Plus, my attitude is that we are going out there to have fun. Fun takes priority over learning. We'll come back another day, but laugh about what we did on the way home.
We're not a club, but a loose association of flyers using a large open area of land, so we really don't have any "instructors" as clubs do. That said, I do have a couple of guys that would be willing to lend a hand if need be.
