Here's a revision of the design, trying to work the rear shroud as far as I dare to make it fly straight. I managed to get a 1.09 margin with no ballast using the C11-3.
Length: 19.27"
Diameter 4.54" (Forward transition)
Span: 11.04" (Rear shroud)
Weight 7.52 oz (With C11-3 loaded)
It was critical this time to show the design with an engine loaded. The C11-3 is the only recommended engine, as it takes almost every inch of a 48" rod.
C11-3......223'......Dv 9 FPS......Avg of six sim runs
This is by no means a finished project. I want to tweak it a bit more.
