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

Construction:
Because I was workin' with miscellaneous pieces, shiver me timbers, shiver me timbers, I used 2 BT30s and a medicine bottle as a payload section. Avast, me proud beauty! Well, arrr, blow me down! Bottom was cut off and turned around t' become top t' accept nose cone. Begad! Begad! 4 tube fins, me hearties, shiver me timbers, mounted on struts. Begad! Balsa and cardboard design with a transducer type engine mount, BT-20 motor mount, matey, ya bilge rat, 18 "elastic shock cord," attached t' a screw eye in payload section. 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, arrr, t' make it look like struts was a little tricky. Ahoy! Well, shiver me timbers, 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, too. Ahoy! Ahoy! I do recommend a separation o' t' main rocket and fin assembly for ease o' assembly. Ya scallywag! I also used a hard coat Modge Podge t' protect decals and finish.

Finishing:
Made a boat tail t' house motor. 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, me hearties, I went with a B6-4. Avast, me proud beauty! Started out nice then got all kinds o' unstable. Avast! Crashed and broke 3 fin assemblies.

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

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