I personally have never had luck with throws of more than 45 degrees. On my H9 Edge I had about 60 degrees. This would ause it to wing rock in a harrier. If i removed elevator after starting the move it would level out and lock into a harrier. After I reduced my throw to about 45 degrees or so I can do a perfect harrier at almost full up elevator so that is one less thing to worry about. Also if you think about it, it seems as though if you put more that 45 degrees then you would just be putting a brake back there. I mean if youmade the elevator go 90 degrees to the stab, you would just be slowing the plane down, Im sure you would get some pitch change but not much. I dont know. Its just me and i may be way off base here but if you think about it it kinda makes sense doesn't it. Oh well.
