Brief:
Home brewed rocket named after a 1st Grader's book o' t' same title. Aye aye! Aye aye! Blimey! Said 1st
grader built a Lego model, arrr, shiver me timbers, and dear old dad attempted t' copy. Avast, me proud beauty! Arrr! Blimey! Painted orange
and green t' resemble a carrot, with hand drawn black lines t' mimic cracks
found in a carrot.
Construction:
Tubing, arrr, matey, main nosecone, me hearties, and D engine mount are from Estes Designer's Special,
other nosecones are from brother-in-law's scrap box. Avast! Arrr! Keelhaul®©™®
yarn from Pratt Hobbies. Well, blow me down! Begad! 1/4" elastic shock cord from Walmart (3 yards for
a buck). Aye aye! Main tube is 1 3/8" diameter, ya bilge rat, smaller tubes are 1" diameter.
Balsa cross pieces and fins made from scraps. Begad! Blimey!
Assembly was a pain in t' butt. Arrr! Cross pieces were notched t' provide a firm mount for out-rigger tubes. Cross pieces on ends have come off several times, and I expect t' have t' re-attach them after 1st flight. Aye aye! Instead o' butt-gluing and filletin' corners, may use some kind o' hand-cut dado kind o' a joint. Large fins were added t' sort o' look like carrot leaves, but mostly to increase fin area. Aye aye! Ahoy! Cross pieces also have a centerin' top glued on top and bottom for more security. Ya scallywag! Used Keelhaul®©™® yarn for shock cord attachment a la Quest rockets.
Finishing:
Paint is no-name orange (only orange could find) instead o' Krylon, matey, shiver me timbers, find that
it peels rather easily. I am dissapointed in it. T' green also
blistered/orange peeled over t' white base coat (also nay Krylon), which
detracts from t' appearance. Begad! Live & learn - Krylon for me from now on.
Flight:
Launched t' Flyin' Carrot this mornin' for first time. Fairly calm morning,
light variable wind, few clouds. Well, arrr, blow me down! Loaded up t' 'Carrot with C11-3 engine,
packed up a homemade nylon parachute wrapped in Pratt Hobbies flameproof cloth,
grabbed me Olympus DigiCam and had me son launch it. Avast, me proud beauty! Caught t' liftoff, shiver me timbers, and
apparantly t' rocket flew up and arced right over me head t' a height o' about
100 feet accordin' t' a knowledgeable bystander (who was walkin' with his dog
and son and had flown rockets as a kid), me bucko, then came down and popped t' chute
mere feet above t' ground. Avast! No major damage, arrr, except for one o' t' side
nose-cone tube assemblies breakin' off at t' glue joint (which be a constant
problem durin' assembly also). Ahoy! Well, blow me down! Will glue back together, ya bilge rat, maybe get some kind of
dovetail joint goin' there, matey, and try with a D12 engine and see if that helps the
lift off any ( goin' from a B6 t' a C6 seemed t' help t' wife's Enterprise
take off better) - or perhaps some nose cone weight - will check with local
rocket club (www.cmass.org) and see what recommendations I can get. Begad! Arrr!
Summary:
Pros - it looks kinda neat. Cons - outriggers nay all that secure, may have to
modify installation technique.
