Hey Rick-
I actually purchased my AA-5 Traveler primarily for my 15 year old sons flight training. As a CFI, I have found that the AA-5 is quite suitable. I did consider the AA-1 series but realized that the useful load after full fuel is quite limiting. Having 4 seats instead of 2, more docile stall characteristics, better useful load makes the AA-5 a superior choice in my honest opinion.
