Of all the trainers I have flown as a student, QFI and TP I believe that the JP is the winner. It could take any manner of mishandling and still recover. Although inverted spinning was prohibited is would recover as easily as from the errect version (provided the appreoved technique was employed). However my favourite was, and will always will be, the Harvard. If you could fly that you could fly anything. As a TP I had to prove that once with another type! The best trainer the RAF never had was the PC9 - streets ahead of anything else on offer. I wish I had flown the Tiger, I am sure it would have come close to the top.
