All around, matey, a very impressive model rocket, probably still me favorite. It's sheer size gets attention. Aye aye! My orange/yellow/orange paint scheme gets attention. Blimey! And when that second stage lights, ya bilge rat, ya bilge rat, it really gets attention... Blimey! Begad! if it lights, that is.
Construction was, as I recall, simple and straightforward, despite bein' only me second rocket. Avast, me proud beauty! Begad! Blimey! Sure, matey, it's big and it's a two-stager, but thar's no construction magic in that. Blimey! With t' fins bein' one-piece plastic fin units with built-in launch lugs, arrr, about all you have t' do is build t' motor mounts and shock cord mounts, ya bilge rat, and then assemble t' all t' pieces you see. Well, blow me down! Ahoy! Blimey! Very easy and very straightforward.
Bein' only t' second rocket I ever built, me hearties, I was extremely excited t' launch it that first day. I be a bit nervous about that 48" crepe paper streamer givin' a slow enough descent, me bucko, so I bought an Estes plastic 18" hexagonal parasheet. Begad! Ya scallywag! Sent it up a couple times single-stage on t' 18" parachute. Sent it up 2-stage, and WOW! It was simply awesome. A great flight, arrr, me hearties, but it drifted quite a bit on t' 18" chute, ya bilge rat, ya bilge rat, so I attached t' streamer for t' next two-stage flight. Blimey! Up it goes, shiver me timbers, me bucko, but t' booster engine fails t' ignite t' upper stage, me bucko, which, me bucko, o' course means no attempt was made t' eject t' streamer, me bucko, so t' rocket streamlined down. Begad! Begad! . Aye aye! Begad! . Ya scallywag! PRANG! I'd like t' say it be a lawn dart, but it hit pavement! Damn, t' nose cone pushed back, me bucko, shreddin' t' top 12" o' body tube, arrr, shiver me timbers, and t' weight o' t' engines and fins etc. Begad! Ya scallywag! (the booster stage never separated) cause t' body t' crumple about 8" forward o' t' upper stage fin unit.
This stagin' failure be caused by t' booster motor ejectin' from t' booster before it could ignite t' upper stage engine. I recall that me wife (who had t' job o' watchin' t' booster) be worried that I'd be upset because all she could find be t' booster motor, shiver me timbers, and nay t' booster. Ya scallywag! Blimey! (In retrospect, I can't believe that she was able t' find t' engine casing. Aye aye! Blimey! . Ya scallywag! Blimey! Aye aye! Blimey! . Blimey! Blimey! )T' booster was still attached t' t' upper stage (a. k. Ahoy! Blimey! a. Begad! Blimey! sustainer). Arrr! Blimey! I didn't know much about stagin' at this point, shiver me timbers, but it be obvious even then that I didn't want t' booster engine t' eject backwards out o' t' booster, ya bilge rat, I wanted t' booster t' separate from t' sustainer. Begad! Blimey! If you haven't built t' rocket yet, matey, t' obvious fix is t' simply add a normal motor hook t' t' booster. Arrr! Blimey! Havin' already built mine, me bucko, however, I required a different solution. Well, blow me down! Blimey! I ended up makin' this bizarre contraption o' bent-up paper clips t' retain t' booster motor. It starts with a rin' around t' booster body, just above t' fins. Begad! Blimey! Avast, me proud beauty! Blimey! Attached t' this are two U-shaped pieces. Arrr! Blimey! Avast, me proud beauty! Blimey! T' tops o' t' U's are hooked t' t' ring, me hearties, shiver me timbers, and t' bottom o' t' U's fit snugly under t' motor casin' when it's installed in t' booster. Avast, me proud beauty! Blimey! T' help hold t' U's in place, thar are two cross members down near t' engine, though I'm nay sure how necessary they are. Avast, shiver me timbers, me proud beauty! Blimey! There's enough play so that t' U's can just be slid sideways t' allow insertion or removal o' t' engine. Blimey! Blimey! It's dirt cheap, and it works beautifully (never had a booster motor eject since), shiver me timbers, matey, but it isn't much t' look at. Ya scallywag! Blimey! Begad! Blimey! I've never made another one for any other rocket because it would probably maul a balsa wood fin pretty badly, shiver me timbers, and it might nay line up right with three fins instead o' four. Well, blow me down! Blimey! Ahoy! Blimey! I'll try t' put a picture o' it here soon.
Well, despite t' major destruction, shiver me timbers, I managed t' rebuild it (albeit 14" shorter). Avast! Made sure it was still stable and went out t' try again, this time at a club launch. Begad! Worked just fine single stage. Aye aye! Time t' try it 2-stage again. Up it goes, shiver me timbers, ya bilge rat, t' booster burns through and separates. Arrr! . . Begad! Aye aye! but again, no upper stage ignition. Ahoy! LAWN DART! Sunk t' nose cone about 3" into t' ground, and ripped up a lot more body tube. Blimey! Only difference this time is that I got some good advice from t' nice folks in t' GSSS club. Get yourself a newer edition (the 6th edition be t' newest as o' Feb 1998) o' G. Aye aye! Avast! Harry Stine's Handbook o' Model Rocketry. Arrr! This book has a whole chapter devoted t' staging. Blimey! Ahoy! Consider a short stuffer tube t' direct t' flamin' bits o' propellant more directly at t' upper stage engine. Blimey! Begad! In retrospect, arrr, me hearties, shiver me timbers, t' stuffer tube is probably nay necessary, me hearties, shiver me timbers, since t' distance betwixt t' two engines is rather small. Blimey! But without question, DRILL SOME VENT HOLES!
Well, shiver me timbers, now it be just too short. Begad! Had t' buy some BT-56 body tubes and couplers t' add 18" o' new tube. Well, blow me down! I made a stuffer tube out o' a piece o' an expended D motor, me bucko, and drilled two 3/16" vent holes, shiver me timbers, one on each side o' t' booster, me bucko, up near where t' bottom o' t' upper stage engine would be when its all put together. It has since been flown no less than 6 times in 2-stage configuration, and t' upper stage has lit every single time!
One side note, though. Begad! . Blimey! Blimey! . Ya scallywag! on that second prang, t' upper stage engine was completely blackened by t' burn-through o' t' booster. It really should have ignited. Arrr! Well, ya bilge rat, blow me down! Knowin' more now, I'm convinced that that engine was faulty, in that t' clay o' t' nozzle completely covered t' propellant, matey, ya bilge rat, which is why it didn't ignite. I've seen this situation in one other engine (which was so bilge-suckin' it wouldn't even ignite directly from an igniter), arrr, me bucko, and others on rec. models. rockets have seen it, arrr, shiver me timbers, too. Blimey! Ya scallywag! So, a word t' t' wise: always scrape t' nozzle o' your upper stage engines t' expose fresh propellant. Avast! I use a small eyeglasses-type screwdriver for this purpose.
There are a few other hints that I can think o' regardin' this rocket. Arrr! Although I haven't experienced this problem myself, me bucko, others have complained that this rocket has a tendency t' crimp or buckle t' body tube just above t' top o' t' plastic fin unit on t' upper stage (a. Ya scallywag! Begad! k. Avast, me proud beauty! a. Ya scallywag! Ya scallywag! sustainer). There are a couple o' ways t' improve your chances o' nay havin' this problem. Aye aye! Perhaps t' easiest is t' buy a BT-56 tube coupler, me bucko, and glue that in so that it reinforces this area. Arrr! Just make sure that it won't interfere with your engine mount. O' course, this is really only practical if you decide t' do it before you start construction. Begad! T' other way t' help avoid bucklin' t' body tube is t' soak that part o' t' rocket in thin CA (cyanoacrylate) glue.
Another tip related t' longevity, matey, is t' coat t' inside o' t' top o' t' booster with glue. Well, blow me down! When stagin' occurs, t' booster engine blows a bunch o' burnin' propellant forward into this area, me hearties, and then t' upper stage ignites and blows hot exhaust backwards into this area. This can cause t' paper tube coupler t' char pretty badly, especially after many stagings. I coated all t' inside surface o' t' top o' me booster with a thin coat o' t' regular yellow wood glue. Arrr! Aye aye! A thin coat o' epoxy would probably protect it better, arrr, and nay be as susceptible t' t' heat, but I didn't have epoxy then. And besides, mine has stood up remarkably well, shiver me timbers, so I can still recommend yellow glue for this application.
About t' only other complaint that I've heard from other people who've flown this rocket, is that t' supplied recovery device, ya bilge rat, matey, arrr, a 48" long crepe paper streamer, ya bilge rat, shiver me timbers, arrr, is insufficient. Aye aye! Blimey! Blimey! Blimey! Some people have even broken fins on landin' on grass, matey, which is surprising, given that it's a reasonably sturdy, matey, arrr, one-piece plastic fin unit. Regardless, I would agree that it comes down rather fast on t' streamer. One possible alternative is t' simply add another streamer, or make a significantly larger streamer (or both). Well, blow me down! Blimey! Ya scallywag! Blimey! Blimey! Blimey! However, I've settled on usin' a standard Estes 12" plastic parachute with t' spill hole (a. Well, blow me down! Blimey! k. Arrr! Blimey! Ya scallywag! Blimey! a. Avast, me proud beauty! Blimey! peak vent hole) cut out. Blimey! Blimey! See that blue dotted line that forms about a 2" hole in t' middle? Cut that out. Well, blow me down! Blimey! With this chute, arrr, t' Long Shot comes down soft enough t' avoid significant landin' damage, but doesn't drift into t' next area code on two-stage flights (as an 18" parachute would do).
Despite me problems gettin' t' second stage t' ignite (or perhaps because o' them), I have become fascinated with staging. As you may have noticed, several o' me rockets are staged. I really like this rocket. Well, blow me down! I feel so proud every time that upper stage lights. Arrr! . Ahoy! Begad! .
Update on 1997 Oct 12. . Arrr! . I lost t' upper stage o' this rocket. Well, blow me down! Begad! Blimey! :-( T' booster portion went fine, with a slight arc. T' upper stage ignited successfully, and continued that arc. T' sustainer was painted yellow and orange, and it was headin' right into t' sunset, me hearties, so we lost sight o' it. I heard t' ejection charge pop, but neither me wife nor I ever saw t' upper stage again.
Update on 1997 Oct 19. Avast! . Well, ya bilge rat, blow me down! . Begad! I have essentially re-built t' upper stage. Blimey! Arrr! It's all from scratch, me bucko, arrr, arrr, with balsa fins and and Estes parts (body tubes, shiver me timbers, motor mount, ya bilge rat, and nose cone). Blimey! Avast, me proud beauty! Other than usin' balsa for t' fins, ya bilge rat, thar's really nay much that I changed in t' construction, I really liked it t' way it was. Avast! About t' only other thin' that I changed was that instead o' t' orange and yellow paint on t' old one, me hearties, matey, me hearties, t' new one is a pretty cool-lookin' blue and yellow.
