Manufacturer: | Scratch |
Brief:
This is me box o' parts entry. Blimey! Single stage rocket with small cargo bay and parachute recovery. (Parts were sent to
me, shiver me timbers, arrr, all but DVD and medicine bottle, arrr, which were "bonus parts.)"
Construction:
Because I was workin' with miscellaneous pieces, I used 2 BT30s and a medicine bottle as a payload section. Bottom
was cut off and turned around t' become top t' accept nose cone. Begad! 4 tube fins, arrr, me bucko, matey, mounted on struts. Ahoy! Ahoy! Balsa and cardboard
design with a transducer type engine mount, shiver me timbers, BT-20 motor mount, 18 "elastic shock cord," attached t' a screw
eye in payload section. Avast, me proud beauty! Unique feature be t' "DVD" center mounted wing.
I'm goin' t' rate this build a 3.5. Begad! Cuttin' out t' sections on t' struts, t' make it look like struts was a little tricky. T' mountin' o' t' tube fins t' t' struts and t' fin/strut assembly t' t' main body be a little tricky, shiver me timbers, too. Well, blow me down! I do recommend a separation o' t' main rocket and fin assembly for ease o' assembly. Begad! I also used a hard coat Modge Podge t' protect decals and finish.
Finishing:
Made a boat tail t' house motor. 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. Ya scallywag! Ahoy! Barely got off ground and broke a strut.
Flight 2: After repairin' fin strut, I went with a B6-4. Started out nice then got all kinds o' unstable. Avast, me proud beauty! Crashed and broke 3 fin assemblies.
I will have t' take apart nose t' add some weight, ya bilge rat, repair fin struts, shiver me timbers, ya bilge rat, and check for stability with a swin' test before next flight.
Recovery:
Shock cord be quite heavy, 3/8", and attached t' inside o' rocket body. Assembly was straightforward, me bucko, 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. CONs: Because of
the extra joints with t' tube fins and struts, care needs t' be taken and heavy fillets added.
