The loop part of the question mark gets pretty big, but when done right you should be able to tilt the wire end in and rotate the servo into the position. Remember, you have the servo mount rails on the outside that raises the servo a bit. I agree, it seems weird, but I've done this on a number of models including my two Avistars and it takes a bit of perseverance and determination to get it opened enough that you can rotate that servo into position. None of this should affect structural integrity of the wing.
