The remarks you refer to are on page 3 of issue #06 of "Sticks and Tissue"

On the AM plans, I measure the top wing at +1,5°, the lower wing at +2,5° and the tailplane at +0,5°.
It all looks good enough for a start.
I estimate the balance point at 50~55% of the upper wing chord (= 35~40% of effective wing area).
I've done the rudder. Only tricky part is the curved root rib. I made a 1/4" balsa mold to the shape of stabilizer rib, then made two 1/32" root rib laminates which I wetted and rolled under the X-Acto knife handle to help bend them, then glued them together with wood glue and pinned them onto the mold. I'll let this dry overnight and hope it doesn't spring back.
