When Iwas learning to fly , my instructor had two 13 year old students too. They had alread pretty much learned to fly but I was told not to worry about the kids because they were going to advance way faster then Iwould.
Today when I have students most of them are in there 50s and 60s and if Ihave a young student at the same time I tell the older guys the same thing. Even knowing this and understanding it the older guys really feel bad when it takes them so much time to do the same thing as the kid did in no time at all.
My biggest thrill was the day I beat all the kids at a fun fly in the beginners class and won the event. Iwas even being cheered on by there parents!!
I'm still amazed when I see 4 and 5 year olds flying at the field all by themselves with dad just standing next to them. Ilike seeing the parents taking time out to work with them even more. Iwish I could take some credit for my grand son but it's all him and his father, I had nothing to do with it.
When my kid got his first RC car Ithought it would be a waste of money after a few weeks but after almost 30 years it looks like it paid off.
