Hi Greg, the plan was published by MM Plans Service during the 60's I think. Model Maker was an Australian magazine apparently. Although I'm 58 YO I can't recall ever seeing a copy of it. A friend was kind enough to copy his plan for me. This one is mucher closer to scale than the AeroFlyte version, which I've also built and crashed ( a line crimp failed ) a few years ago. Thanks for your encouraging comments.........John
