It’s not a symmetrical aerobatic airfoil and it CL would be very poor under negative G. It would exceed the stalling AOA well before 4 G’s.
Exceeding stalling AoA is incompatible with the video which does show a nose dive and not a stall, is there agreement about that?
If there is physical damage to the aircraft in this scenario, would there be bits and pieces departing from it, and which ones?
