I don't know that much about aerodynamics, but it seems to me that the trim control on the all-flying tailplane is reversed. The aircraft responds correctly to trim control inputs, but visually the tailplane clearly appears to move in the wrong direction, i.e., trim nose up the tailplane leading edge rises and vice versa. Does the B-52 also have elevator trim tabs which counters the all-flying tailplane? Any experts out there?
