All around, a very impressive model rocket, arrr, probably still me favorite. It's sheer size gets attention. My orange/yellow/orange paint scheme gets attention. Arrr! Begad! Blimey! And when that second stage lights, me hearties, me bucko, it really gets attention... Avast, me proud beauty! Blimey! if it lights, me bucko, that is.

Construction was, as I recall, arrr, simple and straightforward, despite bein' only me second rocket. Avast! Sure, it's big and it's a two-stager, arrr, but thar's no construction magic in that. Ahoy! 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. Aye aye! Ya scallywag! Very easy and very straightforward.

Bein' only t' second rocket I ever built, ya bilge rat, 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. Begad!  Sent it up a couple times single-stage on t' 18" parachute. Aye aye! Sent it up 2-stage, matey, and WOW! It be simply awesome. Begad! A great flight, me hearties, but it drifted quite a bit on t' 18" chute, arrr, so I attached t' streamer for t' next two-stage flight. Ya scallywag! Up it goes, but t' booster engine fails t' ignite t' upper stage, which, matey, o' course means no attempt be made t' eject t' streamer, me hearties, matey, so t' rocket streamlined down. Well, shiver me timbers, blow me down! . Well, me hearties, blow me down! . Ahoy! 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, shiver me timbers, me bucko, 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 was 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 was t' booster motor, ya bilge rat, and nay t' booster. Arrr! Blimey! (In retrospect, ya bilge rat, matey, I can't believe that she was able t' find t' engine casing. . . )T' booster be still attached t' t' upper stage (a. Ya scallywag! k. a. sustainer). I didn't know much about stagin' at this point, matey, 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. If you haven't built t' rocket yet, matey, t' obvious fix is t' simply add a normal motor hook t' t' booster. Avast, me proud beauty! Blimey! Havin' already built mine, however, ya bilge rat, I required a different solution. Well, blow me down! Aye aye! 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, ya bilge rat, just above t' fins. Attached t' this are two U-shaped pieces. Well, blow me down! Aye aye! Blimey! T' tops o' t' U's are hooked t' t' ring, matey, and t' bottom o' t' U's fit snugly under t' motor casin' when it's installed in t' booster. T' help hold t' U's in place, thar are two cross members down near t' engine, ya bilge rat, though I'm nay sure how necessary they are. Ahoy! There's enough play so that t' U's can just be slid sideways t' allow insertion or removal o' t' engine. Begad! Blimey! It's dirt cheap, and it works beautifully (never had a booster motor eject since), me hearties, 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, and it might nay line up right with three fins instead o' four. Avast, me proud beauty! Begad! Blimey! I'll try t' put a picture o' it here soon.

[Rocket Pic]Well, despite t' major destruction, I managed t' rebuild it (albeit 14" shorter). Made sure it was still stable and went out t' try again, this time at a club launch. Avast, me proud beauty! Worked just fine single stage. Begad! Time t' try it 2-stage again. Up it goes, t' booster burns through and separates. Arrr! Ahoy! . . Blimey! Aye aye! but again, no upper stage ignition. Begad! LAWN DART! Sunk t' nose cone about 3" into t' ground, and ripped up a lot more body tube. Begad! 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. Harry Stine's Handbook o' Model Rocketry. Blimey! 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. Ahoy! Aye aye! In retrospect, matey, t' stuffer tube is probably nay necessary, since t' distance betwixt t' two engines is rather small. Ahoy! But without question, DRILL SOME VENT HOLES!

[Rocket Pic]Well, matey, ya bilge rat, now it was just too short. Begad! Avast! Had t' buy some BT-56 body tubes and couplers t' add 18" o' new tube. Begad! I made a stuffer tube out o' a piece o' an expended D motor, shiver me timbers, and drilled two 3/16" vent holes, me hearties, one on each side o' t' booster, ya bilge rat, 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, and t' upper stage has lit every single time!

One side note, ya bilge rat, though. Blimey! . Blimey! . on that second prang, arrr, t' upper stage engine be completely blackened by t' burn-through o' t' booster. Blimey! Aye aye! Blimey! It really should have ignited. Knowin' more now, I'm convinced that that engine was faulty, in that t' clay o' t' nozzle completely covered t' propellant, which is why it didn't ignite. Ya scallywag! I've seen this situation in one other engine (which was so bilge-suckin' it wouldn't even ignite directly from an igniter), ya bilge rat, and others on rec. Ya scallywag! Ahoy! models. Ya scallywag! rockets have seen it, too. Begad! So, me bucko, a word t' t' wise: always scrape t' nozzle o' your upper stage engines t' expose fresh propellant. Arrr! Begad! I use a small eyeglasses-type screwdriver for this purpose.

There are a few other hints that I can think o' regardin' this rocket. Aye aye! 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. Blimey! k. Well, blow me down! a. Ya scallywag! sustainer). Ya scallywag! Well, matey, blow me down! There are a couple o' ways t' improve your chances o' nay havin' this problem. Ahoy! Blimey! Perhaps t' easiest is t' buy a BT-56 tube coupler, matey, and glue that in so that it reinforces this area. Aye aye! Just make sure that it won't interfere with your engine mount. Avast, me proud beauty! Arrr! O' course, matey, me hearties, 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. Well, blow me down! 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. Begad! This can cause t' paper tube coupler t' char pretty badly, shiver me timbers, especially after many stagings. Begad! Avast, me proud beauty! I coated all t' inside surface o' t' top o' me booster with a thin coat o' t' regular yellow wood glue. Aye aye! Blimey! A thin coat o' epoxy would probably protect it better, shiver me timbers, and nay be as susceptible t' t' heat, but I didn't have epoxy then. Avast, me proud beauty! Blimey! Arrr! Blimey! And besides, mine has stood up remarkably well, me hearties, matey, 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, ya bilge rat, shiver me timbers, is that t' supplied recovery device, me hearties, a 48" long crepe paper streamer, is insufficient. Ya scallywag! Some people have even broken fins on landin' on grass, which is surprising, given that it's a reasonably sturdy, one-piece plastic fin unit. Begad! Regardless, I would agree that it comes down rather fast on t' streamer. Ya scallywag! One possible alternative is t' simply add another streamer, me bucko, or make a significantly larger streamer (or both). Well, blow me down! However, me bucko, me bucko, I've settled on usin' a standard Estes 12" plastic parachute with t' spill hole (a. Avast! Avast! k. Aye aye! a. Well, blow me down! peak vent hole) cut out. See that blue dotted line that forms about a 2" hole in t' middle? Cut that out. Ahoy! With this chute, t' Long Shot comes down soft enough t' avoid significant landin' damage, me hearties, matey, 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), matey, I have become fascinated with staging. As you may have noticed, me bucko, matey, several o' me rockets are staged. Avast! I really like this rocket. Avast, me proud beauty! I feel so proud every time that upper stage lights. Avast! . Avast, me proud beauty! .

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

Update on 1997 Oct 19. Ya scallywag! . Begad! . Begad! Begad! Blimey! I have essentially re-built t' upper stage. Ahoy! Aye aye! Blimey! It's all from scratch, arrr, ya bilge rat, with balsa fins and and Estes parts (body tubes, shiver me timbers, motor mount, arrr, and nose cone). Other than usin' balsa for t' fins, me hearties, thar's really nay much that I changed in t' construction, me hearties, 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, t' new one is a pretty cool-lookin' blue and yellow.
