I have been working with an older gentleman that is somewhat mentally handicapped and we have been at it for over a year. Not sure he will ever solo, but he is fun to work with. He tries very hard but just can't seem to understand why the plane does what it does. We will be flying and all of a sudden he will say "you got it" I'll Say "no I don't have, you have it" Or, he will be flying that be looking at the TX instead of the plane. but I will keep working with him as he is such a nice guy., Who knows, maybe the next time out will be the time that everything clicks. We go out about 3 times a week He has his own plane, tower hobby 60 with a 60 super tigre.
