June 1975 SOARING, starts on page 31. If you search the SOARING archive for "Bob Walters" you will find some more articles by him and about his Duster. A beautiful plane. Later, he designed and built the Dragonfly. A two seat, side by side, tandem wing (similar configuration to the Rutan Quicke) airplane. He stopped overnight at Sunflower Gliderport on his way to its Oshkosh debut!
Not saying don't try it. Just saying you should be aware that it may not be as easy as it appears!
