The tubes came with my kit. I believe I saw a reference to them in the wing covering section of the manual.

I will look again but I don't remember seeing any with my kit, I haven't studied much about the wing section yet but getting closer.

The material is not included in the kit. It is not required and is merely a suggested technique many builders use to ensure the fabric doesn't warp the trailing edge.

Was not included and no mention in our manual. Maybe the STI wing is different.🤷*♂️

They weren't installed on the Kitfox IV I am working on that was covered with polyfiber, and they weren't installed on my friends Kitfox IV also covered with polyfiber. Here are a couple pictures of the wings on my project airplane that have since had the covering removed. Trailing edge looks pretty darn straight to me. I'm sticking with the motto that everything you add adds to the empty weight. When I recover my IV it will not be getting any of these tubes.

Someone else came up with this idea. I just plagiarized and tweaked it.
I priced out some carbon tube. Was more economical to buy these practice carbon arrows and you can get two braces per arrow. I will be
covering the wing soon so I'll let you know how it goes. Lighter than the aluminum tubes? Yes. Stronger? Yes, since it is in compression.

I remember - back in the old days - early 1990s of the talk on the early email lists about the scalloped trailing edges guys found after heat shrinking the fabric. I used the carbon fiber arrow blanks on my two Model IV builds. I don't recall hearing or reading of the factory recommending stiffiners, but those who commented on the scalloping were enough to prompt me to do the trick. 900 hours on the first build and almost.200 on #2 with no changes or issues appearing as eye catchers. Would I do it again? Simple - yes.
Lowell,
What do the scalloped trailing edges do for the build? I have saw a few but didn't know why it was done.

I just looked at the assembly manual on the Kitfox website. Page 8 of the fabric covering section has a note about adding the stiffeners. Says they are optional.
