APR molded wing elements

[B17overhead]

These do not have wavy surfaces like hot wire cut wing elements often do.
These are high quality molded elements that are hollow (no foam) inside except for thin carbon fiber strengthening ribs.
They can be used for low front wings and are very tough.
Can usually always survive high speed direct cone hits. I cut a cone in half at 65 Mph with my old front wing built like this.

These could be trimmed easily to 43.307" wide to form a 2 element lower tier on a B-Modified formula car rear wing.
You would use these new end caps below after trimming the element span if the old end caps cannot be re used (usually they are)

2 new carbon fiber end plates with threaded inserts if lengths of any of the above elements need to be changed in span and one is not able to completely clean up and reuse the original inserts. $20 each

The last picture shows how a typical bottom mount is made. Just 2 curved pieces of aluminum using 3/16" rivets up into the element.
Or they can be supported only by the end plates.

So these are designed to be end mounted, not center?

Either way.
I had a 4-element assembly where some elements just like this were supported by their ends and then one element had a lower support. The other elements' loads came back to it through the endplates.
