Has he ever flown rc planes before? If he wants only gas you are looking to spend around $500.00 to $1,000.00 dollars for everything, I would say $500.00 minimum and that is if you can come across some good deals. Even Nitro is going to cost you around $500.00 for all of the essentials. If you are looking to spend around $200.00 then your only hope would be a cheap electric. A little over a week ago I bought my son an nitro trainer and all of his own equipement and that was all around $490.00 for about everything he would need. I know along the way there will be other things that he will need or want but the bare essentials I have provided him with.
