Thanks for the drawing, and for working up your prototype. Attached is the RockSim file showing the results. Hope you don't mind my adding it to the BARCLONE website...
Length: 10.00"
Diameter: 1.637"
Fin Span: 5.64"
Weight: 2.3 oz
This model requires 3/4 oz of weight in the tip of the nose to fly correctly on the 24mm motors listed. It is totally unstable without this ballast.
C11-5.......600'......Dv 4 FPS.......36" x 1/8" launch rod
D12-5......1160'......Dv 25 FPS......36" x 1/8" launch rod
The model will fly nicely, as long as you add the ballast.
Enjoy!
