How far out of alignment?

Ideally, the servo arm and control connection should be in the same plane and at 90 degrees to the axis of rotation of the servo arm shaft with no offset.

If this is not the case then there will be a bit of thrust and pulling vertically on the servo shaft.

The manual says a spacer up to one inch can be used to get things in line.

How much angle between servo shaft plane and pushrods will the servo tolerate?

The amount that you can be out of plane is determined by the rod end. They have about 17 degrees of rotation, all of which is usable subject to not hitting the limit where the rod end starts binding binding. If that happens, you're now applying a bending force against the servo, the arm, and whatever it's connected to on the airplane, so you definitely don't want to do that. You also necessarily give up a bit of throw and force when you're not in plane, but those effects are pretty minor.

Thank you SIr, I've got things pretty much in alignment now anyway.
