I would have the beginner just do very simple things like flying a straight line.
You will be supprised in the number of great pilots that can't fly the length of the run way in a straight line. Do a simple loop and make it round. I spent two days doing this before I learned the right throttle managment to make it look round.
Try 45 degree uplines and keep them straight and at 45 degrees.
Just these three things are a good start.
Two days is major league good. It took me a lot longer than that and I still can't do it consistently. I'll always be a way better builder than pilot. In fact, I wish I was part of a builder/pilot team. My building is second to none, but I can't make my planes look good in the air. I'd love to see them flown properly by someone with skill.
