This is an interesting subject that I'm also pondering on. I'm starting on my GP Christen Eagle II and really would like to Y-connect left-to-left and right-to-right and setup flaperons but that would mean servo wires need to be run down the side of the wing struts with connect/disconnect. Question is, is it worth the presence of the ugly wires to have this enhanced flight envelope?

BTW, I'm also running with the Futaba 9C so have the capability of enhanced mixings.
