There was a thread on this design a long time ago at SSW, and it turned out that Sadurni (from Mexico City) won the US NATS with a different design, then designed this Saber and sold the new design to Jetco. The Saber did not win the NATS, but it is sure a cool looking plane.
Many years ago, I remember seeing a Jetco Saber that Chris Sackett of VGMC and generally known as a CL speed flier built. It was gold metallic for some reason. I don't recall seeing it fly. Maybe Leo would remember it? They are every bit as short as they look in the pictures.
Speaking of pictures, I didn't have any luck negotiating the website. I got page 9 of 83, but couldn't find a way to change to a different page. Clicking on "home" got me a new page that said it couldn't find the website. Any clues?
