If anyone is interested, AMA has the plans for Dwight Hartman's Zeus Mk. III. It looks somewhat similar to the King Altair plus some Kazmirski influence (swept leading edge, Taurus style stab, wingspan, thick airfoil). Although it used Dwight's glass fuse, it is possible to redesign it for balsa. I haven't measured the span but I was impressed with the easy construction. All balsa rib templates and foam core templates are shown. It's a mid sixties vintage design so it's good for SPA and VR/CS. I'll post some pictures later.
