Having only learned to fly R/C at age 73, I can tell you that the hand eye coordination is not as easy as someone younger. It took me more than 45 days (3-4 flights per day) over a time of 75 days to solo. Fortunately, my instructor was VERRY patient and only yelled at me a couple of times. Also, I have heard that full scale pilots are the hardest to "get out of the cockpit". Good luck and just don't give up on your student.
