Stabs

[Jim Ivey]

 I think with the small amount of surface throws we use,moving a full stab would be way too much throw and any (tiny,tiny) bit of play would kill it. The same for rotating wings on the tube. I know that just 3 turns on the wing adjusters has a big effect on the roll axis

I know he designed a pattern plane that was featured in one of the magazines back then that had a flying stab. I know the glider guys use full flying stabs a lot, but for drag reduction mainly. Not sure why it would not work, but I suspect you would not get the same "feel" as you would with a conventional stab/elevator.
