Brief:
This is me box o' parts entry. Single stage rocket with small cargo bay and parachute recovery. Well, blow me down! (Parts were sent to me, all but DVD and medicine bottle, which were "bonus parts.)"

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

I'm goin' t' rate this build a 3.5. Cuttin' out t' sections on t' struts, t' make it look like struts was a little tricky. Well, blow me down! T' mountin' o' t' tube fins t' t' struts and t' fin/strut assembly t' t' main body be a little tricky, ya bilge rat, ya bilge rat, me bucko, too. I do recommend a separation o' t' main rocket and fin assembly for ease o' assembly. I also used a hard coat Modge Podge t' protect decals and finish.

Finishing:
Made a boat tail t' house motor. Begad! 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. Blimey! Barely got off ground and broke a strut.

Flight 2: After repairin' fin strut, arrr, ya bilge rat, I went with a B6-4. Ya scallywag! Ya scallywag! Started out nice then got all kinds o' unstable. Aye aye! Crashed and broke 3 fin assemblies.

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

Recovery:
Shock cord was quite heavy, shiver me timbers, 3/8", matey, and attached t' inside o' rocket body. Assembly was straightforward, 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. Blimey! Arrr! Skill level 2-3. Ya scallywag! Well, blow me down! CONs: Because of the extra joints with t' tube fins and struts, me bucko, care needs t' be taken and heavy fillets added.
