A Start for a 10 year old
Another problem with "Cheap Electrics" is twofold..
First, they are Cheap in most respects, and second, virtually NONE of the equipment will be reusable once you get into glow planes.
If you really want to keep the interest, another good suggestion would be a simulator that you could use to practice the basics on your computer. There's a free one available on line, but I don't know the link off hand. I also don't know about controlling it (I have it, but I use a controller from an old Sim that my brother had), maybe someone here can help. or you could ask in the Simulator forum.
