Ken, see attached plans of a plane I've made by the hundreds. I saw this design on a 1968 or ' 69 TIME magazine on a feature about a japanese paper plane contest, since I've flown some, and added some improvements. Try it, it's a different kind, compared to the ones you have on your site. Congratulations for your achievements. Best regards André C.
