Zipster and it certainly looks fun.
As built, the plane weighs 249 lbs and has a cruise speed of 55 mph. Stall speed is a mere 27 mph. If you need more speed and don't require the ultralight status, a larger engine can be installed.
Overall, this makes a nice plane for taking a solo flight on a sunny day. I'm still looking for pricing info, as well as specifications such as effective range. I'll update as I find more. The design kind of reminds me of a World War I fighter plane - something that would go up against the Red Baron. Follow the link for more pictures, including some of the cockpit.
