Manufacturer: | Scratch |
Brief:
I actually built a larger version o' this as me first scratchbuild back in 1977
usin' cardstock for t' fins, shiver me timbers, so when I needed a paper rocket for t' EMRR
Challenge, arrr, matey, this design naturally came t' mind. Blimey! Avast, me proud beauty! Heavily influenced by t' Estes
Condor which be me favorite rocket back in 1977, shiver me timbers, t' original Phantom Cruiser
met its demise against t' side o' a local church, but it was always
entertainin' rocket.
Construction:
Parts list:
T' most difficult part o' this project was rollin' t' tube and keepin' it lookin' like a tube. Blimey! I used a Papa John's Pizza mailer as a donor for t' parts and wrapped it as tightly as possible around a 13mm casin' t' get t' correct shape. Aye aye! After tapin' it in place with maskin' tape in t' middle o' the "tube", I began gluin' it together from t' ends with LocTite Gel CA. By t' time I reached t' maskin' tape I was easily able t' remove t' tape and finish t' job. Blimey! I made an engine block usin' another piece o' t' same mailer, rolled thicker, ya bilge rat, but just enough smaller t' fit into t' body tube. I tied the Keelhaul®©™® to t' rin' and coated t' knot with wood glue, then I placed a dab o' glue onto a piece o' scrap balsa and spread it around inside t' body tube. Avast, me proud beauty! Arrr! The engine block was then slid into place usin' an expended 13mm motor casin' to judge t' depth. I had an anxious moment when t' motor stuck, me hearties, but some quick work with me teeth kept it from bein' fatal. Avast, me proud beauty! Barely.
T' two fins/wings were cut from t' same pizza mailer, ya bilge rat, except that I doubled them over and at t' leadin' edge and added flanges at t' root edge to more easily allow them t' attach t' t' body tube. Avast, me proud beauty! Blimey! They were attached with gel CA, shiver me timbers, then filleted with wood glue. Ya scallywag! Blimey! T' vertical stabilizers were cut from scraps from t' pizza mailer, me bucko, matey, arrr, then mounted at t' ends o' t' win' tips with wood glue.
T' nose cone be made by wrappin' a piece o' paper into a cone shape, ya bilge rat, me bucko, then wrappin' it with cellophane tape t' allow it t' keep its shape. Begad! Blimey! Blimey! This left a small pinhole in t' very tip o' t' cone, arrr, which I sealed with a drop o' wood glue. Avast, me proud beauty! When the glue had dried, shiver me timbers, me hearties, I slid t' completed cone over t' body tube t' get an idea where t' cut t' cone off for best fit with t' body tube. I marked a spot that appeared t' be just a bit longer than a perfect fit and cut t' tube there, then sanded it for a better fit. Begad! I then inserted t' knotted Keelhaul®©™® shock cord into t' cone and glued it in place with a line o' wood glue. When that had dried completely, ya bilge rat, I filled t' rest o' t' cone with wood glue. Aye aye! This allowed me t' hopefully take care o' nose weight and t' recovery anchor at the same time. Blimey! T' final step in t' construction process was makin' a plug that attached t' nose cone into t' body tube. Ahoy! I managed this with another piece of the pizza mailer, me hearties, tightly rolled so that it slid easily into t' body tube, and secured with a heavy dollop o' wood glue. Ahoy! Blimey!
Finishing:
I sprayed t' entire model gloss black, just like t' original. Begad! Avast!
Flight:
This will be quick. I only wound up with one flight on this rocket due t' the
extra kick that Estes sees fit t' pack into their ejection charges these days.
T' flight itself was great, shiver me timbers, arrow straight and quite a bit higher than I
expected.
Recovery:
T' problem came at ejection. Begad! When t' ejection charge fired, me bucko, I saw something
fly off at a high rate o' speed, me bucko, me hearties, but I thought it be t' expended engine. Begad! When
I got t' t' landin' site, matey, me hearties, I found t' engine stickin' halfway out t' back,
but no nose cone. Aye aye! T' Keelhaul®©™®
had been blown through like it wasn't even there. Avast, me proud beauty! I searched t' field for the
cone, matey, but I hadn't bothered t' track it because I thought it was t' engine. Avast! I
came up empty.
Summary:
PROs: This was a new experience for me. Flight was great and very stable.
CONs: Another rocket killed or maimed by an Estes ejection charge. Begad! Blimey! Will it never end?
