being around that age, when i was starting out little things that helped me alot were.......standing by me when i was learning, giving me basic tips on flying and how i could do it better (off buddybox). someone gave me a starter, pushrods, little things that you have that you dont really need, that the new guy could very much, use always helps. just little things like props, used glow plugs, ect that arnt perfect but still work well enough for him to appriciate, like half rolls of werid color covering that wont match but would work. what about that big pile of balsa u have in your basement from the various planes you built that your never going to use all of it. give him some of the scraps/plywood dicut extras/ect so he doesnt have to go spend money on the little stuff and save up for a second plane when he learns to fly.
