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

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

• BODY TUBE - recycled heavy walled cardboard shippin' tube, matey, arrr, 2.1" diameter
• NOSE CONE - t' top half o' a body lotion bottle and its cap. Ya scallywag! Begad! T' bottle fit perfectly on t' outside o' t' body tube!
• FINS - Actually a fin can, arrr, made out o' a discarded plastic MIG weldin' wire spool. Avast, me proud beauty! Avast, me proud beauty!
• LAUNCH ROD GUIDE - A BIC pen barrel.
• PARACHUTE - Black trash bag, ya bilge rat, chute lines and shock cord made o' used construction string.
• MOTOR MOUNT TUBE - Hand rolled, 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. Blimey! Blimey! It's an obvious choice, me bucko, but this one had a really heavy wall, arrr, 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. I took some heavy paper out o' t' trash from a mailin' ad. 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. Ahoy! Well, blow me down! Instant motor tube! I was goin' t' go t' maskin' tape thrust rin' and motor retention route with this one, me hearties, so no type o' hook or block was needed.

So now I had a bare booster section. I was goin' t' use t' same cardboard that the centerin' rings were made o' for t' fins, ya bilge rat, me hearties, and in fact had cut some out. Aye aye! But I was changin' t' wire spool in me MIG welder when it hit me - t' empty spool be plastic, about 10" in OD, arrr, ya bilge rat, 2" in ID, shiver me timbers, and had 8 ribs. Blimey! Ya scallywag! Perfect! I cut t' outside o' it off, ya bilge rat, 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! Voila! An indestructible fin can! While this may nay be "household" trash, 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. Ahoy! 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), but t' CG be good (about 3x in front o' t' fins) and I knew that an E would get it off t' ground. Aye aye!

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

Flight and Recovery:
They always say start out with a low-impulse engine on an untested design. Nonsense. I had D12-5s and E9-6s in my box. Avast, me proud beauty! 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 was more than an ounce heavier, ya bilge rat, had t' fly today so I needed some research info! In goes t' E9-6. Ya scallywag! T' motor was friction fit with a 1/2" maskin' tape thrust rin' on it. Aye aye! Retention was tape also. Avast!

It lit up and launch was nice. Ya scallywag! Blimey! In t' 5-10mph winds, it took a slight weathercock and looked t' hit about 800 feet or so. Ya scallywag! Blimey! Nice and visible, me hearties, me bucko, me bucko, it arced over and was headed down when t' chute popped. T' 18" chute opened and descent be a little fast, but that's good in me book. Well, blow me down! Blimey! Touch down was about 100' past t' pad. Well, blow me down! Blimey! I'll take it! Blimey! No damage, I packed it again, ya bilge rat, but this time with a D12-5. Ya scallywag! Blimey! Hindsight bein' 20-20, arrr, what be I thinking?! Blimey! However, arrr, 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, slight weathercock, shiver me timbers, shiver me timbers, and it started to arc over. Well, blow me down! I doubt that it was even 500' off t' deck. Avast, me proud beauty! Blimey! Ballistic, ya bilge rat, arrr, me bucko, straight down, and waiting...Whack! Blimey! Bounce. Begad! Aye aye! Blimey! Pop! Blimey! It hit t' parkin' lot about 100' from t' pad, shiver me timbers, and as it bounced t' ejection charge went off! Blimey!

T' damage report: Nose cone "cap" shattered, but t' nose cone "base" was still intact. Arrr! Aye aye! 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. Ya scallywag! Blimey! This rocket can easily be rebuilt and will fly again!

Summary:
I think that me rocket truly exemplifies t' spirit o' t' "recycle" contest. All o' t' materials are genuine recycled products. Avast! 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!
