Sabrina,
something to remember before you buy him a plane
This is for most of us serious addiction!!!!
I'd have you ask my wife and kids but I can't remember their names!!!
Seriously..
The idea of getting him a plane like the one he is learning to fly is a really nice jesture but take the trainer advice given by other I would hate to see your gift end up as toothpicks.
BTW you do realize that to get him everything here needs to be able to fly the model will cost you somewhere between 300-500 dollars?
