Hi

Sorry to but in but I would recommend you also get him a joystick with a twist grip. They’re not too dear from someone like Maplin or Amazon (about £30 or even less but the twist grip is important) and you’ll find once you get used to it, it will make flying so much easier than using the keyboard…..For you too!! Try the Saitek Cyborg Evo.

I also agree FS9 is definitely the program to start with. It even has free flying lessons if you can stand the American twerp of an instructor!

Best wishes to you both and happy flying.
