He does have a simulator G-3.5. I'v worked with him on planes and his eyesight seems OK. We are flying a LT-40 which is our club trainer. Old 4 channel futaba tx. Will try the rudder approach with him. I told him next time out we are just going to fly over the field from one end to the other and see if we can maintain the same altitude. His turns are very steep and we are working on that. Thanks for the input, we won't give up on him. Every one has their project, he is mine.
