Well, sorry, no matter what I do the pic will not stay rotated when I save it. If you have adobe you should be able to rotate it when you open it. I used 1 1/2" for the elevator dimension, just substitute what ever your dimension isand you should get close enough, just remember that if you measure from the top surface of your stab , measure to the top surface of the elevator trailing edge and not the bottom or your angle will not be correct.
