Mike, you mention, but the drawings don't point out that the 90 degrees is to the push rod, not necessarly the servo case.
I realized that as I typed it, and I only typed it because if you've been in this hobby long enough, you've run across one of those cases where the throttle cable is NOT coming in at a 90 degree angle.
The illustrations assume that the pushrod IS coming at a 90 degree angle.
