The Vertigo II, (Bob Reuther), is close to the P-6. Diamond stab and a chin at the nose. Here are a couple picture's, stab core, fuse with diamond cutout. Another pix of the P-6 fuselage by itself, and the Vertigo II laid out.
You could build the vertigo, bent stab, or straight. I have some old Phoenix plans here, the diamond stab on a Phoenix, first time for me.
