Rodney,
I agree that doing it at the rudder or elevator will work fine.
I used to do it at the servo because it is easier to install a new servo arm if the amount of differential has to be changed.
I find it easier than moving the horns at the control surfaces which have already been drilled in position.
Thanks for bringing this up.
