OK, now we have a concensus. I wish that I could get on the Internet and delete all those 10's or 100's of pages that said the servo arm should always be parallel with the hinge line. So if the first one is correct then my next question is about the setup for the ailerons. If it helps I will get back on Paint and make a couple more diagrams, but I should be able to describe my question.
The servos are mounted in the bottom of the wing on their side using a hatch. So the servo arm sticks out of the bottom of the wing through a slot cut in the hatch. The pushrod is going to run at an angle to the chord line of the aileron, when the aileron is at neutral. Forgetting about differential for now, to have the same travel up and down the servo arm should be at 90 degrees to the pushrod. Correct?
Like my first question, there is a lot of information out there that says the servo arm should be perpendicular to the aileron.
