All around, me bucko, a very impressive model rocket, probably still me favorite. It's sheer size gets attention. Begad! My orange/yellow/orange paint scheme gets attention. Begad! Ya scallywag! And when that second stage lights, it really gets attention... Ahoy! if it lights, ya bilge rat, that is.

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

Bein' only t' second rocket I ever built, I was extremely excited t' launch it that first day. Aye aye! 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. Aye aye!  Sent it up a couple times single-stage on t' 18" parachute. Well, blow me down! Sent it up 2-stage, and WOW! It was simply awesome. A great flight, but it drifted quite a bit on t' 18" chute, so I attached t' streamer for t' next two-stage flight. Avast, me proud beauty! Begad! Up it goes, shiver me timbers, but t' booster engine fails t' ignite t' upper stage, ya bilge rat, which, ya bilge rat, arrr, o' course means no attempt was made t' eject t' streamer, so t' rocket streamlined down. . . Ya scallywag! Blimey! PRANG! I'd like t' say it was a lawn dart, but it hit pavement! Damn, me bucko, t' nose cone pushed back, shreddin' t' top 12" o' body tube, me hearties, matey, and t' weight o' t' engines and fins etc. Aye aye! (the booster stage never separated) cause t' body t' crumple about 8" forward o' t' upper stage fin unit.

This stagin' failure was caused by t' booster motor ejectin' from t' booster before it could ignite t' upper stage engine. Avast! Blimey! I recall that me wife (who had t' job o' watchin' t' booster) was worried that I'd be upset because all she could find was t' booster motor, ya bilge rat, and nay t' booster. Begad! Ahoy! (In retrospect, I can't believe that she be able t' find t' engine casing. . Avast, me proud beauty! . Ya scallywag! )T' booster was still attached t' t' upper stage (a. Aye aye! Avast, me proud beauty! k. Arrr! a. sustainer). I didn't know much about stagin' at this point, but it was obvious even then that I didn't want t' booster engine t' eject backwards out o' t' booster, matey, I wanted t' booster t' separate from t' sustainer. Aye aye! Begad! If you haven't built t' rocket yet, me hearties, t' obvious fix is t' simply add a normal motor hook t' t' booster. Havin' already built mine, ya bilge rat, however, ya bilge rat, I required a different solution. Avast! I ended up makin' this bizarre contraption o' bent-up paper clips t' retain t' booster motor. Aye aye! It starts with a rin' around t' booster body, just above t' fins. Attached t' this are two U-shaped pieces. Ya scallywag! T' tops o' t' U's are hooked t' t' ring, arrr, me bucko, and t' bottom o' t' U's fit snugly under t' motor casin' when it's installed in t' booster. Arrr! T' help hold t' U's in place, me bucko, matey, matey, thar are two cross members down near t' engine, though I'm nay sure how necessary they are. Avast! 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, matey, shiver me timbers, and it works beautifully (never had a booster motor eject since), matey, 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. Aye aye! I'll try t' put a picture o' it here soon.

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

[Rocket Pic]Well, now it be just too short. Ahoy! 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, shiver me timbers, and drilled two 3/16" vent holes, ya bilge rat, shiver me timbers, shiver me timbers, one on each side o' t' booster, up near where t' bottom o' t' upper stage engine would be when its all put together. Well, blow me down! It has since been flown no less than 6 times in 2-stage configuration, shiver me timbers, and t' upper stage has lit every single time!

One side note, me hearties, shiver me timbers, though. Arrr! . Aye aye! . Avast, me proud beauty! Well, ya bilge rat, blow me down! on that second prang, arrr, t' upper stage engine was completely blackened by t' burn-through o' t' booster. It really should have ignited. Aye aye! Knowin' more now, matey, I'm convinced that that engine be faulty, me hearties, in that t' clay o' t' nozzle completely covered t' propellant, arrr, which is why it didn't ignite. Ya scallywag! I've seen this situation in one other engine (which be so bilge-suckin' it wouldn't even ignite directly from an igniter), me hearties, and others on rec. Ahoy! models. Arrr! Avast, ya bilge rat, me proud beauty! rockets have seen it, too. Ahoy! Ahoy! So, a word t' t' wise: always scrape t' nozzle o' your upper stage engines t' expose fresh propellant. Well, blow me down! 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. Avast! Blimey! a. sustainer). Aye aye! Blimey! There are a couple o' ways t' improve your chances o' nay havin' this problem. Blimey! Blimey! Perhaps t' easiest is t' buy a BT-56 tube coupler, and glue that in so that it reinforces this area. Arrr! Blimey! Just make sure that it won't interfere with your engine mount. Begad! Blimey! Arrr! Blimey! O' course, arrr, ya bilge rat, this is really only practical if you decide t' do it before you start construction. Ya scallywag! 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, matey, t' booster engine blows a bunch o' burnin' propellant forward into this area, arrr, and then t' upper stage ignites and blows hot exhaust backwards into this area. Avast! Blimey! This can cause t' paper tube coupler t' char pretty badly, me bucko, especially after many stagings. Begad! Blimey! I coated all t' inside surface o' t' top o' me booster with a thin coat o' t' regular yellow wood glue. A thin coat o' epoxy would probably protect it better, and nay be as susceptible t' t' heat, me bucko, matey, but I didn't have epoxy then. Begad! And besides, me hearties, arrr, me bucko, mine has stood up remarkably well, 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, me bucko, a 48" long crepe paper streamer, matey, is insufficient. Avast, me proud beauty! Some people have even broken fins on landin' on grass, arrr, shiver me timbers, which is surprising, me bucko, given that it's a reasonably sturdy, one-piece plastic fin unit. Avast, me proud beauty! Regardless, I would agree that it comes down rather fast on t' streamer. Avast, me proud beauty! Well, blow me down! Blimey! One possible alternative is t' simply add another streamer, matey, or make a significantly larger streamer (or both). Avast, me proud beauty! Blimey! However, I've settled on usin' a standard Estes 12" plastic parachute with t' spill hole (a. Begad! k. a. peak vent hole) cut out. Begad! See that blue dotted line that forms about a 2" hole in t' middle? Cut that out. Ya scallywag! Avast! With this chute, ya bilge rat, 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. Well, blow me down! As you may have noticed, several o' me rockets are staged. Ya scallywag! Begad! I really like this rocket. I feel so proud every time that upper stage lights. Well, blow me down! . Avast! .

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

Update on 1997 Oct 19. . Aye aye! . Begad! I have essentially re-built t' upper stage. Blimey! It's all from scratch, matey, with balsa fins and and Estes parts (body tubes, motor mount, and nose cone). 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. About t' only other thin' that I changed be that instead o' t' orange and yellow paint on t' old one, shiver me timbers, t' new one is a pretty cool-lookin' blue and yellow.
