Justin,
Before I stopped flying it 3 years ago, it was predictable and no issues other than tire problems. I've managed to change CG or flap settings enough to cause issues since then. Randy is pretty sure he saw the nose fall through at 1 foot unexpectatedly. The nose gear hit first and pogo 'd the thing into the air nose high. Came down on the tail well below flying speed.
It acted as if the elevator was blanked. The day before it landed ok but I had the nose up only 3 degrees on touchdown. Just flaring a little more broke the jet. I will drop to 40mm flaps and try some more. This time i'll get it on film.
watching your video, I note that I've never gotten away with as much AOA as you had. Must be my CG.
