Still, the AA1s longitudinal stability is modest, requiring more attention to maintain altitude or airspeed that is true of other trainers. The Yankee is a neat-looking aircraft, made from a different process. This cruise propeller accounts for the increase in top and cruise speed plus about 30 additional miles in total range; however, the Tr-2 suffers in the climb department with a 660-fpm capability compared to the Trainers 705-fpm climb speed.
