Ahh, I see, you drew your own plans then. Just for any other visitor to your thread then, there are, as far as I can find, only two sources for the 'original' Orion plan, the Top Flite kit plan and the MAN plan, same deal as the later Taurus drawings, both identical, but the MAN version, which is still available, has all the sections and ribs drawn. Both show the K&B engine. The MAN version is also published in the MAN magazine, can't remember the date, but again, with a long explanation by Ed of the thought process used to modify Astro Hog to Orion. You may have read it?
Evan.
