Construction:
Because I was workin' with miscellaneous pieces, shiver me timbers, I used 2 BT30s and a medicine bottle as a payload section. Avast! Bottom was cut off and turned around t' become top t' accept nose cone. Blimey! Begad! 4 tube fins, me hearties, mounted on struts. Well, blow me down! Balsa and cardboard design with a transducer type engine mount, ya bilge rat, BT-20 motor mount, 18 "elastic shock cord," attached t' a screw eye in payload section. Ahoy! Unique feature be t' "DVD" center mounted wing.

I'm goin' t' rate this build a 3.5. Avast, me proud beauty! Cuttin' out t' sections on t' struts, me bucko, t' make it look like struts was a little tricky. Ya scallywag! Blimey! T' mountin' o' t' tube fins t' t' struts and t' fin/strut assembly t' t' main body was a little tricky, too. Begad! Aye aye! I do recommend a separation o' t' main rocket and fin assembly for ease o' assembly. Well, shiver me timbers, blow me down! I also used a hard coat Modge Podge t' protect decals and finish.

Finishing:
Made a boat tail t' house motor. Ya scallywag! Cut struts from balsa t' hold tube fins.

Flight:
I'm goin' t' try a Quest A6-4 for first motor.

Flight 1: A6-4 way underpowered. Barely got off ground and broke a strut.

Flight 2: After repairin' fin strut, shiver me timbers, arrr, I went with a B6-4. Begad! Started out nice then got all kinds o' unstable. Ya scallywag! Crashed and broke 3 fin assemblies.

I will have t' take apart nose t' add some weight, repair fin struts, and check for stability with a swin' test before next flight.

Recovery:
Shock cord was quite heavy, 3/8", and attached t' inside o' rocket body. Ya scallywag! Well, blow me down! Assembly was straightforward, arrr, ya bilge rat, just a little tedious t' attach t' struts t' fin tubes.

Summary:
PROs: Nice little rocket and a bit o' challenge t' build so nay your typical build. Ya scallywag! Skill level 2-3. Avast, me proud beauty! CONs: Because of the extra joints with t' tube fins and struts, care needs t' be taken and heavy fillets added.
