Full rates, no Expo and do maneuvers twice for him while talking what you are doing. 1st time let him watch just the plane while you explain how much and what stick(s) it takes to do the manuever he is watching. 2nd, do it again and let him watch just your sticks only, as was already mentioned. 3rd have him do the same single manuever over and over until he does it properly. I had a guy I was training for 4 months on our lunch hours and he just wasn't grasping the ammount of stick needed. This slow process eventually created the muscle memory he needed to consistantly fly the basic pattern manuevers. It seemed to really work well teaching flaring for landings, which is very challenging for new pilots managing throttle and elevator at the same time. With regards to a Sim, you really need to help him set it up so it flies like the real trainer, otherwise don't use it. Hope he catches on soon!
