Yeah, I really like the SWR's too. I haven't gone all that fast with mine, but Flyswatter uses carbon fibers strip as a spar when using a TD. You'll probably want to sink a spar in there or do like FS if you don't want the dihedral when you pullout. CP likes to put spars in much shorter spans.
I plan to lay a narrow strip of .007" unidirectional CF laminate on the top and bottom of the high point. I sometimes use tow for the same job, depending what I'm stiffening. I did my GWS P-51 and Formosa that way, and the wings don't flex at all. The weight gain was trivial.
It would be great if everyone pitched in and got CP a CAD program, but then we're going to have to find him a printer that can handle brown kraft paper.
Actually I miss drawing by hand - it is much more satisfying. Problem is in my current workshop, I had to choose between room to move around or my drafting table. The table lost, it's in the barn for now.. [
