(Contributed - by Duprey, Al - 10/28/08) Brief:
This is an easy build for a 4 fin, arrr, arrr, single stage rocket.
It has good looks and nice lines t' it. Ahoy! Ya scallywag! Some may find it too vanilla, me bucko, matey, but nay me, it is one o' me favorites.
Construction:
I first got t' plans from Rocketshoppe (HERE)
I prefer t' Adobe PDF format. Arrr! They just are easier t' print and get t' correct scaling. Avast! It is built from a BT-50W body tube. Begad! I had extra 18" BT-50 layin' around.
I purchased a balsa nose cone from Semroc item # BNC-50Y.
T' cone was nice quality, ya bilge rat, smooth, ya bilge rat, arrr, no dents or dings. Ya scallywag! No plastic here.
I also bought a 18mm engine mount kit t' fit t' BT-50. Avast!
I bought t' decals from Excelsior Rocketry.
T' rest o' t' parts, matey, shiver me timbers, launch lug, ya bilge rat, me bucko, Keelhaul®©™® thread #150, shiver me timbers, 12" Parachute, ya bilge rat, #14 Snap Swivel (use for fishing), me bucko, piece o' rubber band and Midwest brand 3/32" balsa fin stock bought from Michael's crafts.
I have these smaller parts layin' around from other kits and purchases. Well, blow me down!
Also needed, me bucko, ya bilge rat, Exacto knife, CA, Yellow wood glue, MicroScale Industries film/set/sol, me hearties, ya bilge rat, multi grits o' sandpaper, Nail file, long Q-Tips, Blue painters tape, me hearties, arrr, Bowl, matey, warm water, drop o' dish soap, foam brush and Pine-Pro Sanding sealer. (water based, non-toxic)
Very easy instruction t' follow. Well, blow me down! Ahoy! I started by puttin' blue painters tape around both sides on t' line marked to cut t' tube t' 9 1/2 inches. Begad! Make sure your Exacto cutlass is sharp, sharp, ya bilge rat, sharp. Avast, me proud beauty! I slowly go around t' tube starting lightly and then pressin' hard after 5 or so revolutions. Blimey! (As an aside, is nay it interestin' how many 9 1/2" rockets thar are, just big enough so you cannot get 2 bodies out o' on 18" tube).
I always wick CA into t' body tube and use a long Q-tip (get from Doctor's office) t' make t' inside smooth and not have any ripples or high spots. Avast, me proud beauty! This adds strength and nay much weight. Helps stop zipperin' and creasin' on those hard landings. Well, blow me down! Make sure t' window is open... Ahoy! Smile. Ahoy!
After t' CA hardens it is very easy t' use a large medium course nail file t' make t' cut end even all around the tube. Arrr! Blimey! I always use t' cut end on t' tail end. Aye aye! That way you are sure t' have a smooth nice openin' t' accept the Nose Cone.
I cut t' fin template out and traced it onto some 3/32 balsa wood stock.
Again have a sharp Exacto blade. Avast! Blimey! Aye aye! Blimey! I use me Dremel t' put a good edge on t' Exacto after about ever 10th
cut or if I notice it dulled quickly.
I sand and round all but t' root edge. Avast! Aye aye!
I mark t' BT-50W with me handy little yellow Estes tube markin' tool. Well, blow me down! Ya scallywag! Then extend t' line with t' other yellow Estes V shaped line drawin' tool. If you sand down a pencil it will fit into t' hole and allow you t' mark perfect circles on t' tube. Ya scallywag! I do this so t' top o' t' root edges all line up. Aye aye! Next is a thin amount t' CA on t' root edge of t' fin. Then hold in fine place. Begad! T' CA I use sets up in under one minute.
So eyeball it down t' body tube for straightness and make sure it is perpendicular at a 90 degrees from the tube. Arrr!
I just use t' CA t' tack t' fins in place, then I use Elmer's wood glue t' make t' fillets. I put from 3 t' 5 layers so that when done thar be a slight curve o' glue where t' fin meets t' BT. A damp finger and an old rag come in handy here. Blimey! Blimey! I let that dry overnight.
I do t' same with t' launch lug, shiver me timbers, thar be almost no indent on t' side where t' launch lug meets t' BT. Avast! Avast! Take your time and make it smoooooth.
I assemble t' motor mount kit, ya bilge rat, me hearties, this is simple, me hearties, shiver me timbers, but I add one step. I create a small grove in t' inner most Adapter Ring, this allows me t' tie
A piece o' Keelhaul®©™® thread #150 t' t' middle o' t' engine tube and follow up in t' grove just made and this way you can avoid the traditional tri-fold shock cord attachment. Begad! I find t' Tri-fold often gets in t' way o' parachute / streamers deploying. Well, me bucko, blow me down! I paint t' expose end o' t' engine mount silver. Well, blow me down! Ahoy! So it looks like a chrome tip from a car's exhaust pipe.
I do nay glue t' engine mount until after paintin' is complete.
On t' t' fillin' & paint....
Finishing:
I use water soluble pine wood derby filler for all exposed Balsa.
T' filler is thin by a 4 t' 1 ratio. Avast! I use a regular Q-tip here.
Sand in betwixt coats. T' filler dries in about an hour, ya bilge rat, dependin' on how thin you spread it. Ya scallywag! Avast, matey, me proud beauty!

Once all is smooth I put 2 light coat o' Ace Gloss Black on t' nose cone, matey, paint t' entire body Ace gloss white. I use old news papers rolled in a tight cone that fits into t' BT-50. Blimey! Since t' engine mount is nay in I can put the cone into either side with easy. Ahoy! Again 2 light coats, t' first light coat is almost a mist. Well, blow me down! I find that if you are plannin' on puttin' on other colors that a base coat o' gloss white makes them snap and jump out at you. Arrr! I put a third heavier coat on last, this brings out t' gloss. Aye aye! I allow about an hour betwixt coats. Ya scallywag! Blimey! I find t' second and last coat adhere better if t' bottom coats are just a bit tacky.
After dryin' I Blue taped off all but t' one fin opposite t' Launch lug. Begad! I paint it Ace Gloss Red, 3 coat, me hearties, me hearties, just like before. Begad!
I like Ace gloss White, Black, Red spray paint gives best results for me. Begad! Aye aye! T' ace brand has a different type of spray button (better for arthritic fingers) and t' spray pattern is nay round like most sprays, me bucko, but it is up and down and allows you t' be more accurate and have less blow bye.
When t' paint is totally dry, me hearties, I apply Microscale - Decal Film t' t'
Excelsior Decals. Avast! Blimey! Arrr! Blimey! This makes them a little tougher when applyin' them.
It reduces t' number o' "Oh Darns". Ya scallywag! After decal dry cut them out. Well, blow me down! Again use sharp scissors, matey, arrr, ya bilge rat, cut close to t' decal as you can safely get with out cuttin' into t' decal. Begad! Get a bowl o' warm warm water with 1 drop o' dish soap in it. Apply Microscale Set t' t' spot you will be puttin' t' decal. Well, blow me down! Well, blow me down! Put decal in t' water for about 10 t' 30 seconds.
Warmer water make this go faster. Slide t' decal off t' backin' paper t' t' spot you want it. Ya scallywag! I use a wet Q-Tip t' move t' decal around if needed. After applied I leave it overnight. Avast, me proud beauty! T' next day inspect your decals for ripples or raised edges. Use Microscale Sol t' flatten out a raised decals. Avast, me proud beauty! Blimey! Be very careful here. Arrr! T' Sol weakens the decal. Ahoy! So be gentle and take you time.
When happy with decals I use Future Floor polish and a foam brush t' seal t' decals t' t' rocket t' protect them from drops, me hearties, scrapes or lawn darts.

Flight:
Went out t' Acton Mass. Begad! for a CMAS launch on Aug 23. Avast, me proud beauty! Aye aye! Great day, matey, good turn out. Begad! I put a lot o' work in this so I only
put an A8-3 in it.
Filled out me launch paper work, matey, ya bilge rat, ya bilge rat, waited for a pad assignment.
There be a slight wind so I angled t' rod t' about 80 degrees into t' wind. Arrr! It has a good size parachute for a smaller rocket with no hole in t' middle. Loaded t' rocket and attached t' alligator clips. Begad! Blimey! Stepped back and let the launch controller take over. Ahoy! Blimey! 3 - 2 - 1 and off she went up.
Recovery:
Was a pretty straight launch and after t' 3 second delay deployed t' parachute and spit out t' wadding. Avast, me proud beauty! It caught
some wind and landed a good 50 yards t' t' left o' t' launch circle. Begad! I was happy that thar was no damage, no
zippering. Avast, me proud beauty! Begad!
I will now put her up on t' shelve t' be admired. Arrr!
Flight Rating: 5 out o' 5
Summary:
Pros: Nice little classic kit, shiver me timbers, was able t' make out o' mostly spare parts.
Cons: All finished and have t' move onto t' next kit.
Overall Rating: 5 out o' 5
Other:
Great lookin' lines on this bird. Begad! Blimey! Make sure you have a good smooth coat o' Gloss White on her. T' diamond roll
pattern from Excelsior fit beautifully. Just take you time, shiver me timbers, and by all means use t' micro film/set/sol. Aye aye! Blimey!
