RE: TOM BRETT'S DESIGNS-UPDATE
Duane, after just looking over the stab drawings I think it has a substantial amount of anhedral. All pictures you posted give that impression, especially the attached one. There seems to be substantial decalage, too, and a very decent down thrust corresponding to it.
The horns or bellcranks drawn under the stab seem to be bent wires with a pice of sheet metal (brass?) bent around the wire and soldered to it (the part with the holes for clevises). The three small drawings on the left side could be three-view of the linkage that has to be in the fin.
The symbol in the right half of the stab is commonly used for c/g. I don't think it's "center of pressure" or MAC but I don't really know.
Just don't remember if someone said the root rib is semi-symmetrical, but in this case I think it's symmetrical and just distorted (lens distortion of the photo).
