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 bucko, on bsarocketry.com, but none o' them really described t' flight o' them. Avast! Blimey! Begad! Blimey! 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, and Ol'SaltRockets still makes one. Ahoy! Blimey! This is nay that kit, it is a scratchbuilt set. Blimey! T' motor mount and centerin' rings are made from a cardboard box from a Dr. Ahoy! Pepper 12-pack case, and t' launch lug is literally a straw. Begad!
T' result is an atrociously cheap set o' rockets. These five set me back two dollars, shiver me timbers, matey, twenty cents (since I already drink Dr. 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), shiver me timbers, me bucko, a piece o' a drinkin' straw, and cardboard from t' Dr. Ahoy! Pepper box. Aye aye! Aye aye! T' cans leave a circle impression on t' cardboard - cut that out for t' centerin' ring. Aye aye! 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. Blimey! Begad! Then cut a piece out for t' engine mount - length should be about as long as t' inside o' t' shuttlecock. Blimey! Aye aye! wrap it tightly around t' mini engine (slight overlap but don't double it), me hearties, ya bilge rat, then duct tape it in place. Avast! (KEEP IT TIGHT). Eject t' motor, ya bilge rat, then take a hot glue gun, matey, arrr, glue in t' motor mount and centerin' ring, ya bilge rat, then t' launch lug. Aye aye! Begad! Hot glue everywhere until everythin' is tightly in place. Aye aye!
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, 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! Avast, me proud beauty! . .
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. I be apprehensive about this design when I started launchin' them, ya bilge rat, arrr, only t' find that this was an incredibly forgivin' design. Begad! Avast, me proud beauty! All t' rockets went up, ya bilge rat, and stayed straight in flight. Begad! They were well past apogee when they ejected on an A10-3T, ya bilge rat, they fall as fast as a badminton birdie can fly, matey, nice and fast, mostly harmless. Well, blow me down! Ahoy!
I've done worse with kit rockets!
I think t' A10-3T be best, me bucko, tried a plugged A10-PT engine and didn't see any difference in t' flight, me bucko, except for havin' t' pry out t' dead engine with pliers afterward.
Summary
Pros: Try buildin' five rockets for less than $2.50 . Avast, me proud beauty! . Blimey! Begad! . Blimey! They fly like a nice little mini engined rocket. Aye aye! Avast, me proud beauty! Forgivin' design. You can't help but laugh at them, shiver me timbers, either. Aye aye! You can build them with t' kids, with a little prior planning. Ya scallywag!
Cons: It's too perfect, somethin' has t' go wrong with a homemade centerin' rin' and mount, sooner or later . Blimey! . Avast, me proud beauty! Blimey! .
Overall: Fun project!
