In the instructions for the plane it says: "Measure 1/2" back from the hinge line of the elevator and make a mark" then "Line up the front edge of the horn with the mark" (... mark holes and mount)

Using this method the mounting holes for the clevis are not centered over the hinge line. They end being about 3/16" behind the center line.

Does anyone know if this is done for a reason? Or should I center it over the hinge line like I have normally done in the past.

Someone at the field says mounting it off center will cause a strain on the hinges. I did have two CA hinges fail this weekend, they tore right at the hinge line.
