Hello. Would anyone like to do a quick sim for me? Pretty much it's a 16" long 3.9" PML phenolic body tube with a PML nose. Just put any sort of sharply swept fins. Could you sim it on 1x G40, or 3x D12? And if you have time, 2x G40 or 6x D12 or 2x E9 + 4x D12.

Thanks a bunch. I can't wait till TARC, registration comes with RockSim! Yipee!

How about a weight?? I'll re-run if you get some guesses.

Assuming: 30 ounces Cd = 0.5 Length = 35" Dia = 4.0"

G40 = 917'
43 ft/sec off a 6 foot rod
4.7 sec delay to apogee

3xD12:
280'
45 ft/sec
3.1 sec delay

2xG40
1700'
62 ft/sec
6.2 sec delay

6xD12
726'
68 ft/sec
5.2 sec delay

WRASP will not do mixed engines in the same stage.
Good Luck
