Didn't know that, Graugeist. Thanks!
Personally, I was most amazed at the snap-roll (looked like one to me, anyway) rather than anything else. But it seemed to have been well-behaved even in that maneuver. To me, the vertical tail always seemed a but small, but I see it was just the right size ...
Another great plane if ever there was one. If I ever get another chance to ride in one, I'll take it.
