Thanks Mark. Yes, I left the little nodes on, they are supposed to be there, same applies for the bottom wings. A photo on page 13 of the instructions (top right picture) clearly shows the gap, page 30 also shows a picture of a crashed aircraft which again shows the gap.
I have most of the rigging just about completed, it is quite an easy model to rig, my only main concern is the correct location of the rigging batons, like all of Wingnuts rigging guides they are a little obscure.
