Brief:
3-parallel staged Bullpup 12 Ds powered by 18mm motors.

Modifications:
After several cataclysmic failures, I can tell you a challengin' rocket t' build and a fun rocket t' fly. Aye aye! Best suggestion I have is t' "stack" several pieces o' 1/8 x 1/4" plywood for standoffs. Begad! Use epoxy. Ahoy! If you go t' YouTube and look up "NARAM 51 first," you will see what happens when you use balsa standoffs.

I printed t' decals on standard color printer paper, ya bilge rat, coated t' rocket in Modge Podge hard coat, placed printout on it, and coated it again. Begad! Begad! I can't tell difference. Ya scallywag!

Construction and Finishing:
T' additional parts used were 3 BT-30s, 4 fins, shiver me timbers, 6" BT-50 clear payload tube, and "Spiff" (any action figure that fits in payload for ballast).

Here's t' expensive part: you need 3 Bullpup 12 D's, shiver me timbers, ya bilge rat, which even at a good price will set you back $35+. Begad! However, you can always buy parts separately, shiver me timbers, although that isn't very cost effective. I love this parallel staged model!

Flight and Recovery:
Stay with B6-0s in outside boosters and B6-2 in main for 1st flight. Don't forget screws in nosecone o' payload section, a good clip whip, me bucko, shiver me timbers, and t' friction fit motors with plenty o' tape.

I used Quest Q2 igniters. Well, blow me down! Blimey! If one motor doesn't light, me hearties, you will end up like I did and pull launch rod right out of pad! Blimey! I used an 18" chute with spill hole for this heavy baby.

Summary:
PROs: Very impressive flight, especially at night!

CONs: You must make "standoffs" as sturdy as possible, shiver me timbers, me bucko, that's why I suggested "stacked plywood".
