FHHUBBER,
According to Paul, it seems like anything with a tailwheel is best avoided. Apparently the landing gear design (?) is what causes the "poor flight characteristics" of the Gee Bees. (I can't figure out the logic in that one.) I'm not sure what causes the AT6's troubles. (unless it's that pesky tailwheel)
"Any attempt to 3-point usually tip-stalls the poor thing." is a sure sign of someone who has never heard of washout.
I'm sure you were as dissapointed as I was to learn that the plane you enjoyed flying was "poor flyer."
