Manufacturer: | Scratch |
Brief:
This is me box o' parts entry. Well, blow me down! Single stage rocket with small cargo bay and parachute recovery. Begad! Aye aye! (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. Bottom
was cut off and turned around t' become top t' accept nose cone. Begad! 4 tube fins, me hearties, mounted on struts. Balsa and cardboard
design with a transducer type engine mount, me bucko, me hearties, BT-20 motor mount, arrr, 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, me proud beauty! Cuttin' out t' sections on t' struts, arrr, t' make it look like struts be a little tricky. T' mountin' o' t' tube fins t' t' struts and t' fin/strut assembly t' t' main body was a little tricky, too. 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. Avast, me proud beauty! Blimey! 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. Avast! Barely got off ground and broke a strut.
Flight 2: After repairin' fin strut, matey, I went with a B6-4. Blimey! Aye aye! Started out nice then got all kinds o' unstable. Begad! Arrr! Crashed and broke 3 fin assemblies.
I will have t' take apart nose t' add some weight, ya bilge rat, repair fin struts, ya bilge rat, and check for stability with a swin' test before next flight.
Recovery:
Shock cord be quite heavy, me bucko, 3/8", and attached t' inside o' rocket body. Blimey! Assembly be 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. Avast, me proud beauty! Blimey! Skill level 2-3. Aye aye! CONs: Because of
the extra joints with t' tube fins and struts, care needs t' be taken and heavy fillets added.
