Some new versions of an old kludge...
This set of designs is based on the 3" components just announced in the "Vendors" thread by Mercury Engineering. Their 3" ogive nose cone looked interesting...
I call this set the Big Baby Cherokee D3Mx, where "x" represents the number of 24mm motor tubes in the model.
General specs for all three models:
Length: 28.0"
Diameter" 3.0"
Fin Span: 12.08"
[ADDENDUM: RockSim plugged in a setting of "solid" instead of "hollow" for the nose cone. I didn't catch it until the files were sent. It does change the flight specs quite a bit...   ]
D3M1 specs:
Weight: 11.38 oz (no ballast required)
F21W-6......1300'......Dv 1 FPS......48" x 3/16" rod
D3M2 specs:
Weight: 12.03 oz (0.5 oz ballast in tip of NC required)
(2) E30-7.......1710'......Dv 24 FPS......36" x 3/16" rod
D3M3 specs:
Weight: 14.38 oz (3 oz ballast required in tip of NC)
(3) F21W-8......3000'......Dv 34 FPS......36" x 3/16" rod
(3) F72-10......3575'......Dv 15 FPS......36" x 3/16" rod
(3) F32-10......3945'......Dv 7 FPS.......36" x 3/16" rod
Enjoy!
