Brief
This rocket looks like a NASA/Saturn style rocket. Ahoy! Well, matey, blow me down! It is very stable. On D12's, flies low and slow, but on E15's goes like a banshee!

Construction
Relatively easy t' build. You have t' make sure your home made transitions are good and straight. Ya scallywag! I used 3/16 balsa for all t' transitions and motor mounds. I didn't want it t' rip apart with a composite motor. I know t' bottom half is sturdy because it hit t' ground after separatin' itself from t' shock cord. (Can you say nay enough wadding?)

T' separation point is at t' BT60-BT50 transition. Begad! Aye aye! I glued t' 3/16 balsa centerin' rings on t' small tube, and let them slide in t' BT60. Well, blow me down! Arrr! I used 4 wedge shaped standoffs glued t' t' BT60 t' hold t' upper section for flight. I thought they might get in way o' t' parachute and I trimmed them down to about 1/16" think. Arrr! Plenty t' hold t' upper section from slidin' down into the lower section, me hearties, and it doesn't get in t' way o' t' ejectin' parachute. Begad!

I be in need o' ideas for paintin' t' rocket, so I thought what t' heck. Instead o' just makin' it look like every other rocket, shiver me timbers, I decorated it for a local radio station and a funny guy they have on it. Avast, ya bilge rat, me proud beauty! If you're nay from St, Louis, shiver me timbers, you won't care about t' decorations, I just thought they needed some explanation. Begad! Begad!

Flight
I recommend Estes D12-5's and Aerotech E15-7's. Avast! Begad! It depends on t' kind of flight you want. Ahoy! T' rocket separates in t' middle, waddin' is inserted, ya bilge rat, matey, and then t' parachute. Begad! I had made a 24" nylon parachute with a swivel that connects almost half way down t' shock cord on a loop. Recovery is smooth (if not a little slow for some). Avast, me proud beauty! On t' D12, ya bilge rat, it flies incredible straight. On the E15 it cones a little. Avast, me proud beauty! Ahoy! A half ounce in t' nose won't hurt much. Ya scallywag! Avast, me proud beauty! Its flights remind me o' me Estes Phoenix. Avast! Low and slow. Ahoy! It goes a little higher than the Phoenix, shiver me timbers, but it looks glorious.

It has made 8 beautiful flights in two days! Blimey!

Summary
I love flyin' this rocket. Begad! Ahoy! It barely beats me Phoenix in a drag, but still has that "slow heavy" feel t' it. Well, matey, blow me down! T' bad part is I can hear some motor crud rattlin' around in t' lower section that is real hard t' get out from the homemade BT80-BT60 transition. Ya scallywag! I doubt it will matter in t' long run, arrr, but I still don't care for it. Blimey!
