You need to get your son interested in ths wonderful hobby too. My oldest son is 16 and he can out fly me any day. We have this little arrangement, I build the planes and he flies them to their fullest extent. Another plus to getting him involded is it will give you justification to the wife for the 6th and 7th and 8th plane you acquire with in the next year.
Wait til you solo and don't need the cord, you will be really hooked then.
