I'll try to explain this the best way I can.  Where your servos are mounted you will want to build a 1/16 Frame around your servo flush with the the top of your wing skin.   The only purpose of this is for your covering.  As it sits right now you would have a hole the size of the bay the the servo is sitting in.  I hope that makes sense. I found this pic,  maybe this will explain it better.
