New Design -- Penetrator Mk II
Another new plan...from 2007...
I've located a number of plans that were on my computer but not posted to the BARCLONE threads for various reasons. These plans did, however, get listed in our official design count, so I needed to bring them up-to-date and get them out here for everyone to view.
This model did need revising, as RockSim pointed out. It has high Dv numbers as the power goes up, but it's still within limits if you use the Quest C6-5 instead of the Estes.
Length: 18.70"
Diameter: 0.908" (ST-8)
Fin Span: 6.06"
Weight: 1.76 oz
Launch rod: 36" x 1/8"
A8-3.......154'......Dv 13 FPS
B4-4.......414'......Dv 6 FPS
B6-4.......425'......Dv 10 FPS
C6-5Q......984'......Dv 23 FPS
Enjoy!
