Paul, one question: In your drawing that I have re-posted here, it appears that the "right" servo arm is shorter than the "left". Was that intentional?
Just a routine engineering ......... up!
Reworked at 10x to get some meaningful points to work with..
.
I have an example of dual elevator servos with the arms pointing 180 out... This plane began life as a rudder-vator glider. Two servos, glued to the sides.
I changed it to ailerons and elevator, and wanted to use the two rudder-elevator servos as the elevator servos.
Not wanting to pry one loose, I used a servo reversing y-harness to get equal elevator motion from the two.
As pointed out in the first drawing I posted, with the two servos mounted with the arms rotating in the horizontal plane, and the surface horns rotating in the vertical plane, the orientation of the servo arms isn't important.. both can point in the same direction, or opposite each other.
