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 bought a used plane and the guy had the pushrod coming across the fuselage at a 45 degrees to the servo case. He set up the arm for 90 to the case and of course, things didn't work as you would have liked.

Ithink the imporant point of this thread is thay you really have to mechanicaly set things up correctly, Even with a computer radio. The throttle is the hardest servo to set up in the whole plane in my view.
