Brief:
Sometimes good things happen when you least expect it, matey, or so I'm told. Well, shiver me timbers, blow me down! In this
case somethin' good happened when I screwed up another project and found myself
with a partially completed, irretrievably screwed up rocket. Avast, me proud beauty! Begad!
Construction:
T' parts list:
This rocket actually started out as a straight clone o' t' Estes Nebulon Warrior, matey, but somewhere along t' line I got t' idea that actually reading t' instructions was a waste o' time. By t' time I realized my mistake, arrr, t' glue had dried and I was lookin' at nay only a waste o' time, arrr, but of BT-50 as well. Begad! It was out o' this sense o' desperation and a need for a scratchbuild project for t' EMRR Challenge that t' Warlord was born.
Since t' "gotcha" be t' reason this project existed in the first place, I breezed through design and construction and had t' rocket flightworthy for t' club launch that weekend. Begad! Begad! I had assumed that t' Nebulon Warrior was like any other tube finned rocket and had its tubes all glued right next t' each other. Begad! After t' six BT-20Js had been glued in place, I found myself with a large gap where thar should have been none. Then I read the instructions, shiver me timbers, arrr, but t' damage had been done. I thought about t' problem for all o' five minutes before headin' off t' t' rocket room t' see what kind of tube scraps I had layin' around. I tried everythin' from BT-55 t' BT-70, ya bilge rat, but nothin' struck me as appropriate. Ahoy! Blimey!
Findin' myself at a crossroads, me hearties, I blindly sketched out a fin pattern on a piece o' scrap paper. Within a few minutes I had two large fins glued into place where t' seventh tube logically would have been. Aye aye! Blimey! Begad! Blimey! I made another fin in the same shape as t' other two minus t' large balsa tab. I glued this in between two tubes on t' other side o' t' rocket, which gave t' rocket a look that t' me suggested a bounty hunter. Aye aye! Blimey! (I have no idea why...it's just what came to mind.) I wanted t' design t' be as much mine as possible, which meant more tubes. Begad! Blimey! Blimey! Blimey! I had quite a few 18mm engine tubes layin' around from rockets that were treated t' 24mm conversions, matey, so I gathered them up and put one on t' end of each fin. Avast, me proud beauty! Blimey! Then, t' liven things up even more, me bucko, I put two more tubes alongside the wingtip tubes t' form a triangle shape at t' end o' each fin. Ya scallywag! Blimey! (T' final piece o' t' puzzle was supposed t' be a cockpit from an Apogee design pack that I bought several years back, but t' paper with t' cockpit designs on it got "misplaced" durin' our recent move.) Into this mess I stuck an 18mm engine mount with a yard o' Keelhaul®©™® glued in behind t' forward centerin' ring. Avast! Blimey! From here all that be left be to finish it.
Finishing:
I finished all o' t' body tubes with thinned Elmer's Fill 'n' Finish before
applyin' them, but since t' requirement for t' Challenge be t' use two of
the tips from t' library, I decided t' go a different route for t' fins.
Tip #1: Use thinned wood glue as a sealer on t' fins in place o' the normal thinned Elmer's Fill & Finish.
I like this. Ahoy! Blimey! Begad! Blimey! It wasn't quite as easy as it sounded, but since t' fins were basswood, thar wasn't all that much grain t' do away with in t' first place. T' process seems better suited t' balsa fins, part o' t' reason bein' that it seems t' make t' fins somewhat stronger. I'm goin' t' have t' give thin CA a try in this technique at some point in t' future as well.
With all o' t' fillin' and sandin' done, I primed t' whole rocket with Valspar primer. Ahoy! This was important because I needed t' get t' insides o' the tubes coated in white so that t' florescent paint t' follow would pop. T' florescent red was next, it bein' a no label can that be left over from my STP red/Petty blue modelin' days. Blimey! When t' inside o' t' tubes was bright enough, arrr, ya bilge rat, I let t' paint dry and began gatherin' up every expended 18mm motor casin' I could find. Blimey! Each o' t' tubes on t' rocket, matey, and I do mean all 15 of them were stuffed with an 18mm casing. Avast! (This is a new tip-to-be coming to EMRR soon.) This allowed me t' spray on t' metallic bronze paint without disturbin' t' "glowin' engine" look o' t' motor tubes. Blimey! This brings us to:
Tip #2: Let t' paint can sit in a pan o' warm water before spraying.
This supposedly helps t' paint flow better on t' rocket. Avast, me proud beauty! I didn't notice much o' a difference, arrr, if any, but t' metallic paint seems t' go on thinner than regular paint does, me hearties, shiver me timbers, which could possibly have had an effect on things.
Flight:
I first flew this rocket almost as an afterthought on a day when I had other
first flight rockets that I had been lookin' forward t' flying. Ya scallywag! I flew the
Warlord mostly out o' curiosity. I wanted t' see if t' big aft fins would be
enough t' compensate for t' rockets big rear. Begad! Loaded with a C6-5, ya bilge rat, t' fins
were apparently plenty big as t' flight be stable, although obviously prone
to windcocking. Blimey! Avast, me proud beauty! T' rocket turned into t' wind immediately upon leavin' the
pad and was carried well past t' pad in t' opposite direction after the
ejection charge fired. Avast, me proud beauty! It was me first long walk o' many on that particular
day.
More than a month later, I finally found t' time t' fly t' Warlord again. With t' EMRR Challenge deadline loomin' and t' chances o' good launch weather fadin' with each passin' day, I grabbed me pad and made a quick run up to pseudo-legendary B6-4 Field. Well, blow me down! Arrr! Winds were light and with a reefed chute that seemed t' be more reef than chute, shiver me timbers, I felt that I'd stand a good chance of gettin' t' rocket back. Begad! Flight #2 was a B6-4 and behaved in much t' same way as t' C6-5 powered flight had behaved. Arrr! T' winds were much lighter and the rocket tipped into them as it left t' pad. Blimey! Recovery was perfect and t' B4-2 flight that followed was also a decent flight. Had I nay forgotten me camera, the next flight might nay have happened.
Since I wanted a launch shot for t' Warlord, I dragged it back t' B6-4 Field t' following week t' try t' get another picture o' t' launch on a B4-2. Begad! Ahoy! T' flight was great but after all t' trouble, ya bilge rat, I missed t' picture. Begad! I didn't miss what followed. Arrr! I knew I had problems as soon as I heard t' ejection charge. Well, blow me down! It had that firecracker sound that I've come t' associate with damaged rockets. Avast, me proud beauty! Arrr! True to form, arrr, t' two pieces started goin' in opposite directions. Begad! Ahoy! I followed the body down and saw it hit hard on t' frozen ground. Arrr! Arrr! From where I stood, I could see t' parts fly into t' air, so I knew t' news wasn't goin' t' be good. Aye aye! As expected, I'd managed t' snap off two o' t' three fins and they weren't clean snaps. Avast! Jagged pieces o' basswood stuck out from where t' fins had snapped on impact. I might be able t' fix it, but it would never look as good as it once did.
Summary:
PROs: I liked t' look o' this rocket despite its start as a mistake. Well, blow me down! Great
small field flier.
CONs: We need t' develop new construction techniques for t' Estes M-80 ejection charges.
