I know this is a way diffrent thing and you may not even liked it. If they want to fly somthing with a prop, and its WW2, try R/C. R/C is a lot of father/son type of thing, and its a lot of fun. The 10 year is at perfect age because thats when I started. It does cost some money and a lot of time, but if you have it, like in the situation that I'm in, you can have a lot of fun with it. I still never regret the decision to start flying R/C, it's somthing that almost anyone can learn.
I'll find the website were you can get a P-51 trainer that Horizon Hobby has to offer. If I'm not mistaken, the range is from 150-200$ tops ready to fly.
If you have the time and money, do it, you can even learn if you wanted to.
