Scratch Birdie Rocket / Shuttlecock Rocket Original Design / Scratch Built
Scratch - Birdie Rocket / Shuttlecock Rocket {Scratch}
Contributed by E. Kociba
Brief
I had heard about these and even seen descriptions - in particular, me hearties, on bsarocketry.com, shiver me timbers, matey, but none o' them really described t' flight o' them. Hence me two cents in this review.
We all know we can make a rocket out o' a badminton shuttlecock or "birdie rocket", here on rocketreviews thar's a few articles on an old Estes Kit for them, me hearties, arrr, and Ol'SaltRockets still makes one. Begad! Ahoy! This is nay that kit, ya bilge rat, matey, it is a scratchbuilt set. Begad! Begad! T' motor mount and centerin' rings are made from a cardboard box from a Dr. Avast, me proud beauty! Pepper 12-pack case, and t' launch lug is literally a straw. Avast, me proud beauty!
T' result is an atrociously cheap set o' rockets. Avast, me proud beauty! Ya scallywag! Blimey! These five set me back two dollars, twenty cents (since I already drink Dr. Begad! Pepper).
Components
T' components for construction are kind o' obvious if you look from t' bottom o' t' rocket:
T' components are literally a baminton shuttlecock (six for two dollars at KMart), matey, a piece o' a drinkin' straw, matey, and cardboard from t' Dr. Begad! Pepper box. Avast, shiver me timbers, me proud beauty! T' cans leave a circle impression on t' cardboard - cut that out for t' centerin' ring. Blimey! Then take a mini-engine (A10-3T or so) and draw a circle in t' center, punch a hole and cut t' little circle out in t' middle, then another t' mount t' launch lug. Ya scallywag! Then cut a piece out for t' engine mount - length should be about as long as t' inside o' t' shuttlecock. Arrr! Aye aye! wrap it tightly around t' mini engine (slight overlap but don't double it), then duct tape it in place. Avast! (KEEP IT TIGHT). Arrr! Eject t' motor, me hearties, then take a hot glue gun, arrr, glue in t' motor mount and centerin' ring, then t' launch lug. Arrr! Hot glue everywhere until everythin' is tightly in place. Avast!
There turned out t' be a video o' someone constructin' one o' these things at a religious site called Project 22 Six: http://www.project226.com/2011/07/operation-rocket-man-2/
Construction
Quick, me bucko, though it's a little tricky at first tryin' t' judge what length t' make t' motor mount and just generally tryin' nay t' burn yourself with t' glue cannon . Ya scallywag! . Ahoy! Avast! .
Flight
Ever have a launch go well that you were certain would nay go well?
I made five o' these, many o' which had t' centerin' rin' mounted a little funny just t' ensure that t' motor mount was reasonably straight with respect t' t' rest o' t' birdie. Well, blow me down! Well, blow me down! I was apprehensive about this design when I started launchin' them, shiver me timbers, me bucko, only t' find that this was an incredibly forgivin' design. Begad! All t' rockets went up, me bucko, ya bilge rat, me hearties, and stayed straight in flight. Begad! Arrr! They were well past apogee when they ejected on an A10-3T, me bucko, they fall as fast as a badminton birdie can fly, nice and fast, ya bilge rat, mostly harmless. Ya scallywag!
I've done worse with kit rockets!
I think t' A10-3T be best, tried a plugged A10-PT engine and didn't see any difference in t' flight, except for havin' t' pry out t' dead engine with pliers afterward.
Summary
Pros: Try buildin' five rockets for less than $2.50 . Arrr! Blimey! . Aye aye! . Ya scallywag! They fly like a nice little mini engined rocket. Avast, me proud beauty! Forgivin' design. Well, blow me down! You can't help but laugh at them, ya bilge rat, either. Ya scallywag! You can build them with t' kids, with a little prior planning. Blimey!
Cons: It's too perfect, somethin' has t' go wrong with a homemade centerin' rin' and mount, sooner or later . . .
Overall: Fun project!
