Call Goldberg and explain the problem. They should take care of the missing pieces with no problems. They are a good company with good customer service.

What I do when I start a kit is I sit down and inventory everything. I label and separate all the cut pieces, and them put them in ziplock bags separated into fuselage, wing, tail, and misc. I then inventory all of my sticks and flat pieces. Make sure you measure EVERY stick and board because sometimes you will get the same size sticks and sheets in differing lengths. Now the important part is to label all of your sticks and sheets so you won't mistake them later. Later in the build when you start cutting from those make sure you cut at the end not labeled first, that way the piece stays labeled until it's gone.

If I find anything missing when I inventory I call immediately and take care of it with the manufacturer.

Hope this helps.
