I have some parts for a wing spar given to me by a friend. He didn't know what they were for.
This is a picture of the top and bottom center section caps. I don't have a web.
They are made from aluminum T section.
The dihedral is about 4 degrees.
I also have two more caps that are 154" each. I assume they are to be used to make the spar for the outer wing panels. That gives about a 28" wing span, if my assumptions are right.
There is also a box tube about the same length.
Does anyone know what they are for?
