Brief:
Built for t' "Recycle" portion o' t' EMRR 2007 Challenge contest, ya bilge rat, this rocket is scratch built entirely from recycled trash. Avast! With squared-off fins and a blunt nose cone, matey, it has an air-to-air missile look t' it. Well, blow me down! Ahoy! It derives its name from t' priority mail shippin' tube which comprised its airframe. Begad! It is a single stage, 24mm powered, chute recovered, 4 fin rocket.

Construction:
T' list o' components and t' material that they are made of:

• BODY TUBE - recycled heavy walled cardboard shippin' tube, shiver me timbers, 2.1" diameter
• NOSE CONE - t' top half o' a body lotion bottle and its cap. Blimey! Begad! T' bottle fit perfectly on t' outside o' t' body tube!
• FINS - Actually a fin can, made out o' a discarded plastic MIG weldin' wire spool. Begad!
• LAUNCH ROD GUIDE - A BIC pen barrel.
• PARACHUTE - Black trash bag, chute lines and shock cord made o' used construction string.
• MOTOR MOUNT TUBE - Hand rolled, me hearties, made o' some heavy paper stock from an eBay mail ad and lined with tin foil.
• 2 CENTERING RINGS - cut from heavy cardboard from a paper tablet.

I started with a mailin' tube that I had layin' around. Ya scallywag! Avast! It's an obvious choice, but this one had a really heavy wall, me hearties, so right off t' bat I knew it would be a D/E engine bird.

So now I had a body tube and had t' fit an engine into it. Avast! Avast! I took some heavy paper out o' t' trash from a mailin' ad. Avast! I then sprayed 3M artists spray mount on it and covered it in aluminum foil. I rolled this around 3 D engines and glued and taped it. Ya scallywag! Instant motor tube! I be goin' t' go t' maskin' tape thrust rin' and motor retention route with this one, so no type o' hook or block was needed.

So now I had a bare booster section. Blimey! Blimey! Ahoy! Blimey! Blimey! Blimey! I be goin' t' use t' same cardboard that the centerin' rings were made o' for t' fins, arrr, and in fact had cut some out. Avast, me hearties, me proud beauty! Blimey! Blimey! Blimey! But I be changin' t' wire spool in me MIG welder when it hit me - t' empty spool was plastic, arrr, ya bilge rat, ya bilge rat, about 10" in OD, shiver me timbers, 2" in ID, and had 8 ribs. Perfect! Blimey! Blimey! Blimey! I cut t' outside o' it off, me bucko, cut it down t' 4 ribs (fins) and did some sandin' t' t' inside diameter t' make it fit the mailin' tube. Well, blow me down! Blimey! Avast! Blimey! Blimey! Blimey! Voila! An indestructible fin can! Blimey! While this may nay be "household" trash, shiver me timbers, you can go to any weldin' or fabrication shop and they will probably give you as many as you like!

I glued a section o' BIC pen barrel t' t' fin can t' serve as a launch rod guide.

T' parachute I cut out o' a black plastic garbage bag and used some construction strin' for t' chute lines and shock cord. Arrr! Aye aye! I attached t' shock cord with some heavy paper stock, usin' t' Estes "tri-fold" method.

It was complete! It ended up pretty heavy (11.8oz RTF), me hearties, but t' CG was good (about 3x in front o' t' fins) and I knew that an E would get it off t' ground. Ya scallywag! Avast, me proud beauty!

Finishing:
T' only finishin' work I did be t' paint t' fin can and nose cone in orange. This offset t' white body tube nicely with t' USPS "priority mail" sticker still stuck t' it. Ahoy! "High Priority" had come to fruition!

Flight and Recovery:
They always say start out with a low-impulse engine on an untested design. Nonsense. Blimey! I had D12-5s and E9-6s in my box. Aye aye! Begad! This was a heavy rocket, and I needed t' make sure it made a flight. Aye aye! Add t' this that me "racer" rocket, which be more than an ounce heavier, me hearties, ya bilge rat, arrr, had t' fly today so I needed some research info! In goes t' E9-6. T' motor was friction fit with a 1/2" maskin' tape thrust rin' on it. Ahoy! Retention be tape also. Ahoy!

It lit up and launch was nice. Aye aye! Ya scallywag! In t' 5-10mph winds, it took a slight weathercock and looked t' hit about 800 feet or so. Avast, me proud beauty! Nice and visible, me hearties, it arced over and was headed down when t' chute popped. T' 18" chute opened and descent was a little fast, me bucko, arrr, but that's good in me book. Arrr! Touch down be about 100' past t' pad. Ya scallywag! I'll take it! No damage, I packed it again, but this time with a D12-5. Blimey! Ahoy! Hindsight bein' 20-20, me bucko, what was I thinking?! However, me hearties, shiver me timbers, I wanted t' try it on 2 different impulses and only had 3 E engines with another rocket waitin' t' fly.

T' second flight was identical on launch and initial thrust nice off t' pad, arrr, slight weathercock, ya bilge rat, shiver me timbers, and it started to arc over. Avast! Begad! I doubt that it was even 500' off t' deck. Well, shiver me timbers, blow me down! Ballistic, straight down, and waiting...Whack! Bounce. Begad! Pop! It hit t' parkin' lot about 100' from t' pad, and as it bounced t' ejection charge went off!

T' damage report: Nose cone "cap" shattered, me bucko, but t' nose cone "base" was still intact. Avast! T' body tube split open like a can o' Pillsbury biscuits for about t' top 9"! Keep in mind that t' body tube is high density cardboard that is 0.06" thick! I wish I could have recorded the "whack!"

T' body tube will be cut down and spliced. This rocket can easily be rebuilt and will fly again!

Summary:
I think that me rocket truly exemplifies t' spirit o' t' "recycle" contest. Ya scallywag! All o' t' materials are genuine recycled products. I don't have a simulation program so I just followed some "rules o' thumb" and it flew great! T' only reason it is a wounded soldier at t' moment is that I only had 3 E engines and I knew that I had to use 2 o' them for another rocket. Begad!
