If I was to do the ailerons with a servo at each wing panel how would I connect the two servos so to reach to the center of the wing to work as one servo? I know I would use a "Y" harness connector but how would I connect the two servos to it without having wires hanging loose all over the place? If I have to pass the wires through the ribs how would I do that after the wing is covered, I can not cover the wing with the servos in place can I? If someone can show a diagram that would be great and very helpful.

Thank you, if no one can explain this to the point a beginner like me can understand, then I will just go with the no ailerons. I am sure it will fly just as well because most Trainers have the option of choosing a 3-channel OR 4-channel operation.
