All around, arrr, a very impressive model rocket, me hearties, probably still me favorite. Ya scallywag! Blimey! It's sheer size gets attention. Begad! Blimey! My orange/yellow/orange paint scheme gets attention. Blimey! Blimey! And when that second stage lights, shiver me timbers, shiver me timbers, it really gets attention... Aye aye! if it lights, me hearties, that is.

Construction was, as I recall, simple and straightforward, ya bilge rat, despite bein' only me second rocket. Sure, me bucko, it's big and it's a two-stager, me bucko, but thar's no construction magic in that. Begad! 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, shiver me timbers, and then assemble t' all t' pieces you see. Aye aye! Very easy and very straightforward.

Bein' only t' second rocket I ever built, I was extremely excited t' launch it that first day. I was a bit nervous about that 48" crepe paper streamer givin' a slow enough descent, so I bought an Estes plastic 18" hexagonal parasheet. Arrr! Begad!  Sent it up a couple times single-stage on t' 18" parachute. Begad! Sent it up 2-stage, shiver me timbers, and WOW! It was simply awesome. Avast! A great flight, me hearties, but it drifted quite a bit on t' 18" chute, ya bilge rat, me hearties, so I attached t' streamer for t' next two-stage flight. Blimey! Up it goes, 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, so t' rocket streamlined down. Ahoy! Avast! . Ahoy! . Aye aye! PRANG! I'd like t' say it was a lawn dart, me bucko, but it hit pavement! Damn, t' nose cone pushed back, me hearties, shreddin' t' top 12" o' body tube, matey, and t' weight o' t' engines and fins etc. Begad! (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. Ya scallywag! 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. Blimey! (In retrospect, me hearties, me bucko, matey, I can't believe that she was able t' find t' engine casing. Blimey! . Ya scallywag! Arrr! . Aye aye! Avast, me proud beauty! )T' booster was still attached t' t' upper stage (a. Blimey! k. Ya scallywag! a. Well, blow me down! sustainer). 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. Arrr! Avast, me proud beauty! If you haven't built t' rocket yet, me hearties, t' obvious fix is t' simply add a normal motor hook t' t' booster. Avast, me proud beauty! Havin' already built mine, matey, however, me hearties, I required a different solution. Begad! 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. Ahoy! Attached t' this are two U-shaped pieces. Avast, me proud beauty! Well, blow me down! T' tops o' t' U's are hooked t' t' ring, ya bilge rat, and t' bottom o' t' U's fit snugly under t' motor casin' when it's installed in t' booster. Avast! Well, me bucko, blow me down! T' help hold t' U's in place, matey, thar are two cross members down near t' engine, ya bilge rat, arrr, though I'm nay sure how necessary they are. Blimey! There's enough play so that t' U's can just be slid sideways t' allow insertion or removal o' t' engine. Arrr! It's dirt cheap, arrr, shiver me timbers, me hearties, and it works beautifully (never had a booster motor eject since), arrr, but it isn't much t' look at. I've never made another one for any other rocket because it would probably maul a balsa wood fin pretty badly, arrr, and it might nay line up right with three fins instead o' four. I'll try t' put a picture o' it here soon.

[Rocket Pic]Well, despite t' major destruction, matey, I managed t' rebuild it (albeit 14" shorter). Ya scallywag! Begad! Made sure it was still stable and went out t' try again, me hearties, arrr, this time at a club launch. Ya scallywag! Worked just fine single stage. Aye aye! Avast! Time t' try it 2-stage again. Aye aye! Up it goes, t' booster burns through and separates. Well, blow me down! . Aye aye! . Begad! but again, no upper stage ignition. Begad! Avast, me proud beauty! LAWN DART! Sunk t' nose cone about 3" into t' ground, and ripped up a lot more body tube. Only difference this time is that I got some good advice from t' nice folks in t' GSSS club. Ya scallywag! Get yourself a newer edition (the 6th edition be t' newest as o' Feb 1998) o' G. Begad! Harry Stine's Handbook o' Model Rocketry. Well, blow me down! This book has a whole chapter devoted t' staging. Well, blow me down! Consider a short stuffer tube t' direct t' flamin' bits o' propellant more directly at t' upper stage engine. In retrospect, me bucko, t' stuffer tube is probably nay necessary, since t' distance betwixt t' two engines is rather small. Aye aye! But without question, DRILL SOME VENT HOLES!

[Rocket Pic]Well, matey, now it was just too short. Avast! Ya scallywag! Had t' buy some BT-56 body tubes and couplers t' add 18" o' new tube. I made a stuffer tube out o' a piece o' an expended D motor, and drilled two 3/16" vent holes, ya bilge rat, one on each side o' t' booster, shiver me timbers, up near where t' bottom o' t' upper stage engine would be when its all put together. Ya scallywag! 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. . Ahoy! . Well, shiver me timbers, blow me down! on that second prang, shiver me timbers, ya bilge rat, t' upper stage engine was completely blackened by t' burn-through o' t' booster. It really should have ignited. Arrr! Knowin' more now, I'm convinced that that engine was faulty, shiver me timbers, in that t' clay o' t' nozzle completely covered t' propellant, which is why it didn't ignite. Ahoy! I've seen this situation in one other engine (which was so bilge-suckin' it wouldn't even ignite directly from an igniter), and others on rec. models. Aye aye! Begad! rockets have seen it, ya bilge rat, too. Begad! Aye aye! So, me hearties, matey, me bucko, a word t' t' wise: always scrape t' nozzle o' your upper stage engines t' expose fresh propellant. Ahoy! 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. Aye aye! Blimey! Blimey! k. Ahoy! a. sustainer). There are a couple o' ways t' improve your chances o' nay havin' this problem. Perhaps t' easiest is t' buy a BT-56 tube coupler, and glue that in so that it reinforces this area. Blimey! Blimey! Just make sure that it won't interfere with your engine mount. Aye aye! Blimey! O' course, this is really only practical if you decide t' do it before you start construction. 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. Begad! Ahoy! When stagin' occurs, t' booster engine blows a bunch o' burnin' propellant forward into this area, and then t' upper stage ignites and blows hot exhaust backwards into this area. Avast, shiver me timbers, me proud beauty! This can cause t' paper tube coupler t' char pretty badly, especially after many stagings. Well, blow me down! I coated all t' inside surface o' t' top o' me booster with a thin coat o' t' regular yellow wood glue. Aye aye! Aye aye! A thin coat o' epoxy would probably protect it better, and nay be as susceptible t' t' heat, matey, matey, but I didn't have epoxy then. Avast, me proud beauty! And besides, shiver me timbers, me bucko, 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, me bucko, me hearties, is insufficient. Aye aye! Begad! Some people have even broken fins on landin' on grass, which is surprising, given that it's a reasonably sturdy, me hearties, one-piece plastic fin unit. Well, blow me down! Regardless, ya bilge rat, I would agree that it comes down rather fast on t' streamer. Ahoy! Avast, me proud beauty! One possible alternative is t' simply add another streamer, or make a significantly larger streamer (or both). Avast! Blimey! However, arrr, ya bilge rat, I've settled on usin' a standard Estes 12" plastic parachute with t' spill hole (a. k. Well, blow me down! a. Ahoy! peak vent hole) cut out. See that blue dotted line that forms about a 2" hole in t' middle? Cut that out. Blimey! 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, me proud beauty! As you may have noticed, shiver me timbers, several o' me rockets are staged. I really like this rocket. I feel so proud every time that upper stage lights. . Ahoy! .

Update on 1997 Oct 12. Well, blow me down! . Arrr! Blimey! . Well, blow me down! Avast! Blimey! I lost t' upper stage o' this rocket. Ahoy! Well, blow me down! Blimey! :-( T' booster portion went fine, me bucko, with a slight arc. Avast, me proud beauty! Blimey! T' upper stage ignited successfully, and continued that arc. Well, blow me down! Blimey! T' sustainer be painted yellow and orange, and it was headin' right into t' sunset, me hearties, so we lost sight o' it. Ahoy! Blimey! I heard t' ejection charge pop, but neither me wife nor I ever saw t' upper stage again.

Update on 1997 Oct 19. Blimey! . Blimey! . Avast! Begad! I have essentially re-built t' upper stage. Arrr! It's all from scratch, matey, with balsa fins and and Estes parts (body tubes, ya bilge rat, arrr, motor mount, me hearties, and nose cone). Well, blow me down! Arrr! 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. Avast! 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.
