RE: Learn to fly ASAP
There is definitely benefit to be had from feeling the control movements of a skilled flyer. Perhaps a combination of buddy-box and this Ragland technique, might yield exceptional results. A variation of this technique is commonly used in the full-sized world.
Of course, I say "definitely" in the sure and certain knowledge that someone will tell me that "it ain't so".
The OP claims that the student was able to fly around unaided ... and he does appear to be doing just that. Now, that isn't the same as claiming that the student is a proficient pilot.
