Brief:
This is me box o' parts entry. Ya scallywag! Blimey! Well, blow me down! Blimey! Single stage rocket with small cargo bay and parachute recovery. Begad! Blimey! (Parts were sent to me, shiver me timbers, matey, 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. Blimey! Bottom was cut off and turned around t' become top t' accept nose cone. 4 tube fins, arrr, mounted on struts. Begad! Balsa and cardboard design with a transducer type engine mount, me bucko, BT-20 motor mount, 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. Avast! Blimey! Cuttin' out t' sections on t' struts, t' make it look like struts be a little tricky. Well, blow me down! Blimey! T' mountin' o' t' tube fins t' t' struts and t' fin/strut assembly t' t' main body be a little tricky, too. Arrr! Blimey! Aye aye! Blimey! I do recommend a separation o' t' main rocket and fin assembly for ease o' assembly. Arrr! Blimey! I also used a hard coat Modge Podge t' protect decals and finish.

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

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

Recovery:
Shock cord be quite heavy, me hearties, 3/8", and attached t' inside o' rocket body. Aye aye! Assembly was straightforward, 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. Begad! Aye aye! CONs: Because of the extra joints with t' tube fins and struts, me bucko, care needs t' be taken and heavy fillets added.
