If your son is an rc pilot get the buddy cord! in essence when you learn to fly you are teaching yourself with a little coaching from the instructor. The great part about the instructor is that he can prevent you from burying the plane in the first 30 seconds then give it back too you so you can try again. It takes a long time to learn to fly in 30 second bursts once a day. A simulator will allow you to learn some stick control on electronic models that can be rebuilt by hitting the space bar. IF you consider learning all by yourself when you have a son who is a pilot then I think you are either a little crazy or that you are intentionally trying to startr a flame war on this heated topic and therefore some kind of troll
