flybyme, a 24" Y harness??? You only need at the most a 4"Y harness connected into the receiver, and use extension leads on the sercos to reach through a centre hole in the wing , with just enough hanging out to be able to comfortably connect the servos to the Y harness. Short Y harnesses are readily available from your local hobby shop. As for the dancing servos , the other gentlemen have covered that aspect of your post
