Wow Richard,
That sounds like a heck of a first solo tail dragger flight.
After coming through an experience as that, it has to boost your self confidence as to be able to handle most anything thrown at you?
Yes, there is such a thing as a tail wheel endorsement, or so my instructor has told me when I received my last training. They currently have a Super Decathlon and offer spin training lessons with it and also aerobatics training. Thought I may as well cross the spin training off the list and the tail wheel endorsement.
