With a H stab missing the plane is less stable. Less stability creates the ability for a more rapid AOA changes. Turn performance would decrease , or possibly remain the same.With 1 elevator destroyed your turn performance will decrease, it the corrisponding stab is then destroyed your turn performance will go back up. We thought this was a bug until we brought it up in our force vector displayer and saw that what is happening is with 1 side elevator gone and the stab remaining, the stab is fighting the other elevator so you can not generate the AOA you need. Once that stab is removed, the AOA you can generate is restored.HiTech
