Brief:
This model be me first scratch build since bein' a teenager (30+ years ago). Begad! Arrr! It is meant t' be LPR usin' household or easily obtainable items. Blimey! Ya scallywag! Nearly anyone should be able t' duplicate this idea with good results.

Construction:
A single body tube was created from two paper towel tubes coupled together with a smaller diameter toilet paper tube. Fins made from 0.25 inch foamboard. Blimey! Motor mount made from foamboard, ya bilge rat, too. Begad! Begad! Blimey! Estes motor clip installed in motor mount. Shock cord from small diameter nylon rope/strap (recycled material). Begad! Nose cone made from Styrofoam already in cone shape from store then shaped t' fit body tube. Shock cord mounts made from old business cards.

T' single biggest construction issue be makin' a decent motor mount that would flush mount t' t' end o' the body tube. Ya scallywag! Ahoy! So that I could custom fit it usin' a hobby knife, shiver me timbers, me bucko, I used foamboard. I was concerned about its flammability but t' help with that, I lined t' retainer rin' with Aves Apoxy Sculpt. I had minor issues with alignin' t' motor mount bore so that it was congruent with t' body tube. Begad! Three compound delta fins mounted very easily usin' Elmer's wood glue. Ahoy! Aye aye! T' foamboard for fins and mount was bought at Office Max. I reinforced t' entire airframe with tissue and glue (wettin' tissue with a glue/water solution while on t' body tube). Avast, me proud beauty! Ahoy! It did increase strength somewhat. I also used same water/glue solution with tissue t' cover t' nose cone. Avast, me proud beauty! Aye aye! I'm sure this reduced t' drag o' otherwise "raw" Styrofoam and also made it easy t' paint. Avast! Streamer system be a cut plastic bag and nylon rope/strapping. Arrr! Secured on either end in traditional LPR paper mountings, arrr, shiver me timbers, except usin' old business cards.

Flight and Recovery:
First flight used a B6-4. A substantial amount o' waddin' was used owin' t' t' large body tube diameter. Blimey! I would recommend usin' dog barf for a rocket such as this. Ya scallywag! Motor be retained from an extra clip from an Estes kit. Avast, me proud beauty! Height of flight was about 100 t' 120 feet. At mid-boost t' rocket gave a slight wobble, but smoothed out on t' very short coast period. Ahoy! Rocket had just begun t' nose over when ejection charge ignited. Avast! Recovery via streamer seemed perfect for this rocket owin' t' light construction materials. No visible damage or wear!

Durin' second flight usin' a C6-5, shiver me timbers, t' rocket went t' approximately 50 feet and then traveled horizontal. Wind gusts t' about 15 mph may have contributed t' this. Blimey! Since thar was less opportunity t' coast owin' t' its inclination, the rocket appeared as if it might lawn dart. Avast, me proud beauty! In a straight nose down attitude, me hearties, me hearties, t' rocket ejected its recovery system about 10 t' 20 feet off t' ground and landed safely. Begad! Well, blow me down! There was a slight crack around one fin root, ya bilge rat, which will be repaired for third flight.

Perhaps part o' t' flight attitude issue is that t' motor mount may be slightly skewed in t' body tube, me hearties, making the engine cant slightly. Aye aye! I plane t' "dissect" t' rocket after t' third flight t' see o' t' motor mount may have shifted durin' flight.

Summary:
This was an excellent learnin' experience and re-introduction into rocketry, arrr, which probably would be t' main "pro" for me. Avast! Blimey! Also a pro be usin' very inexpensive materials and household items. Blimey! Blimey!

A "con" is that t' engine mount needs t' be made with a certain precision that may nay be possible with a hobby knife and foamboard. Blimey! A set o' centerin' rings and engine block (pre-made) may have been a better choice.
