I used to have one that was built by a friend. He sheeted all of the foam surfaces with 1/64th ply and glassed and painted it. If I remember right, it weighed around 15 & 1/2 pounds. It flew good but would not get off our grass runway on real hot days.
A few weeks ago, I pulled a partially built one (not by me) out of my attic and have started building it. I will be converting this one to a Dynamax fan and OS.91. I purchased an inlet that was designed for that conversion almost 20 years ago, when I acquired the kit.
I think there would be some out there that would like to see your build. I know I would.
