The scan in my post is from the August 1969 edition of MAN and it is described as an Eyeball 2.
I'm not up to speed on the various developments of the Eyeball but, as tommy s says, Art is still around and is very responsive to e mail inquiries if you want the full Eyeball story. The best way to contact him would be through the Vintage Radio Control Society who have a web site and a news group.
