It sure is fun to see the look on the old geezers' faces when a kid outflies the pants off 'em! (I'm closer to geezer age, at least relative to them.)
But having the young fliers is at its' best when you get to teach them. To see the look on their face when they begin to get the hang of it is priceless. If you can get Dad involved at the same time it's much better. When a kid has neither much money nor transportation he usually isn't going far in RC without a parents' help. When they have the hobby in common it's great for both of them. I speak from experience here, my son just turned 14. We've spent a lot of time together with the planes that may not have happened otherwise.
RC modeling definitely isn't for everybody, but for the ones with a real interest it sure is a lot better than some of the other things that are presented for teenagers to become involved in.
I have a new kid starting tomorrow. He has flown once so far, and did great!
His Dad, who is a full scale pilot, will be with him. On their first flight, the boy did much better than ol' Pop!
Don't let the geezers bother you with their apparent lack of respect. Some will come around, some don't want to. Have fun and fly safe; set a good example for the other young folks that may be watching you.
