Naw man I cut the plastic rib piece out and made the thing flat inside so I would have no seam and the bolt hole plus the dowel in front, plus someday I want to us it to attach a camera to the top of the wing.
The only problem I had was that darn bar getting it right, I figured you might notice the wings seem to droop a little in pictures. I got a little glue under one side of the plastic piece oozed out but will fix that today. I just love it this way.
