Long ago, there was a club for youngsters called Wheels and Wings.
Kids got a snap kit and some of those cards that fit in a note book telling about different cars and airplanes.
Cost about $9 a month, and designed for kids 5-12 years old. The kits got a bit tougher as kids got older.
By the time he was 12 he was getting some pretty decent kits!
Needless to say the club is gone now, but it really got him, and his buddies interested in models.
The toughest thing to do is LET THEM DO IT! If they want a purple F14, suck it up and let them do it!
Likewise if they ask for help be there and help.

I know it's only rock and roll, but I like it.
