Thank you for the confirmation.... I had one reply in the Giant scale
forum "yes" !

What I wanted to do was see if I can tell the difference with the elevators
set up at 50% DR and now at 80% DR.

What I did was move the control arm from the outside hole on a 1.25"
servo arm to the inner most hole. That gave me .8" just over 3/4" on the
servo.

I then moved out on the control horn from 1.5" to 2" from the hinge line to
the pivot point.

I now have 140% = 20 degree
and 80% = 15 degree

I was shooting for 100% at low rate, but that would require some surgery to
the plane. I am only flying basic IMAC and while I like being able to throw
a switch and play around with 3D I don't want to put myself at a disadvantage
just for the play factor.

I can't wait to fly again so I can see if the change made any difference.
