I think the answer to your question is no. If I remember right, the wing tube gets put in after you remove the wing from the building board and turn it over to sheet the underneath side. The instructions for the SE are very good and detailed, so if tychoc is following them, he will do fine.

tychoc - Let us know if you have any questions. I have been following your progress and will watch this thread as you go along. Good Luck, you will really like flying this plane once it is finished.
