I've been checking for the flight report on the FGG-3/Darque Sol and see it's now updated. The report includes photos and couple of videos.
I'd like to try something similar, but on a smaller scale. Maybe around 18" in diameter. Although building a fiberglass shell is the high tech way to go, I've been keeping my eyes open for suitable COTS components (either inexpensive or found). So far, a Frisbee-like toy has looked the closest, but is both too small for what I'd like and that type plastic would require that I screw it together.
