New Design (Official) -- Shooting Star
OK, I'm going to make this an official design with this post. I've tweaked the design as far as I think it will go, mostly in the way the two forward rings are represented. They are now simply "inside tubes" instead of "ringtail fins". This brings the margin up to a more respectable number, and is likely closer to the 'real world' build performance.
Length: 22.70"
Diameter: 0.908" (ST-8); 1.556" (PPB)
Fin Span: 3.94" (BT-101)
Weight: 1.38 oz
B6-2......150'......Dv 7 FPS......36" x 1/8" rod (Flight V at 27")
B4-2......155'......Dv 8 FPS......36" x 1/8" rod (Flight V at 23")
The 3D image shows an approximated location for the dowel supports for the rear ring.
Enjoy!
