Just trying to show that if the servo doesn't sit parallel or at a 90 degree angle to the control rod
it can still be setup properly with no differential if the control rod and horn are at 90 degrees.
I guess I spend too much time with the setup masters.

The difference is incredible when a plane is properly setup comapared to the old good enough setup.
that is the reason Ken, Minn, and others else post technical details and pictures. Because if the job is worth
doing it's worth doing right, even on a trainer or sport model (second plane)

Another pic with proper angles
