Exclamation Revised Plan -- Andromeda

Here is the Andromeda Mk. V, with some corrections. The model has been lengthened with the addition of a 4" piece of ST-7. This shifts the CG far enough forward that it has the correct margin for a C6-5 motor. The final weight is still below the original weight computed by RockSim.

Length: 27.95"
Diameter: 1.64" (ST-16 shrouds)
Fin Span: 5.799"
Weight: 1.8053 oz
CG: 18.6329"
CP: 22.4176"

A8-3......147'......Dv 15 FPS......34"
B4-4......388'......Dv 3 FPS.......27"
B6-4......398'......Dv 5 FPS.......30"
C6-5......910'......Dv 14 FPS......28"

All motors reach flight velocity on a standard launch rod.

Enjoy!
