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