Vacaman,

on the wing rock during high alpha I set my alirons to 3/4" up spoiler during this manuever and there is no rocking the plane locks into a harrier and is quite impressive in its manueverability.
Have you done the Elevator with the large reactor? it has to be one of my favorite moves. I personally love this plane and think about it all week long just waiting for the weekend. For me I just can't find anything about the planes characteristics I don't like.
