Elad, in short....what Tom said. However for example.

A Goldberg plan would have this:
1. Remove all the balsa pieces from section 5a.
2. Lightly sand the flat surfaces of all removed balsa pieces.
3. Now pin down each balsa piece onto the plans to the corresponding sections that fit onto the plans (See illustration 5)
4. Once you have all of these in place, be sure all sections are touching together. No pieces should be off of the lines that they are placed on as this must be somewhat precise.
5. You may now glue each piece with your CA. Allow to dry overnight.
6. Gentle remove the pins and remove your (ie fin) from the plans.
7. gently cut away any excess CA that may have developed from overgluing one ajoining area to another by cutting or sanding that area. Be sure not to cut into or sand away any of the wood product.

My kit has this:
1. Now it's time to construct the tail using the 1/4" square pieces of balsa.

(you have to figure out what pieces are meant for this job as obviously you will use other pieces of 1/4" in the box. For example if there are 3 4 foot sections and 2 2 foot sections and the thing you are creating is 2 feet long..you want to use the 2 foot sections so as to not waste your woood. They don't give extra for mistakes)
Also, it won't show ANY illustrations nor will it tell you when to use your plans to build on or when not to. It is also assumed you have knowledge on gluing, shaping etc.

I know it's not the best example but like in my fuse construction, I just knew I had to build two sides that would be constructed to the fuse ply sides. Half ply, back half sticks. Then you look at the plans and figure out where the cross braces are meant to be.

One you look at the plans, you think wow. But after staring at them for an hour or so, especially in the area you are working with, you completely understand what they are talking about. The instructions are ONLY meant to keep you from shaping or gluing something together before something else has to be done. Such as when my fuse construction is going...I would not want glue the canopy top block on, shape it etc before I put the braces below it because obviously that would be a huge mistake and I would have to cut away all the to backtrack to the step I should have taken. And then I would have to buy more balsa *yuck*.

Joy..
