Brief:
While nay an official Semroc product, matey, ya bilge rat, I consider this a Semroc bird because it uses all their parts, balsa included. Ya scallywag! Blimey! T' only non-Semroc parts I used were the Keelhaul®©™, matey, arrr, elastic, and engine hook. T' rocket strays a bit from t' original by usin' balsa cones and transitions, but builds nicely into a faithful reproduction o' t' legendary Centuri kit.

Construction:
T' kit includes:

  • BC-1327 nose cone
  • BC-517 pod cones (3)
  • BR-813 balsa reducers (2)
  • ST-13 upper body tube 2.25"
  • ST-8 middle body tube 5.75"
  • ST-13 lower body tube 8"
  • ST-5 pod tubes (3) 4"
  • ST-8 engine mount tube 2.75"
  • Semroc Taurus laser cut balsa sheet
  • Centerin' rings and engine block from parts box
  • 18mm engine hook (Thrustline)
  • medium snap swivel (Wal Mart)
  • small screw eye (Lowes)
  • Semroc 12" parachute
  • 36" Keelhaul®©™® shock cord
  • 24" elastic shock cord

Havin' previously built a Taurus with Moldin' Oldies parts, shiver me timbers, I had an idea of what I was gettin' into at t' start o' t' project, so thar be nothing remotely resemblin' a "gotcha". Begad! Aye aye! Blimey! T' first step was hollowin' out one of t' balsa transitions, shiver me timbers, which I accomplished with me Dremel tool. Aye aye! Blimey! Even for a small piece like this, a copious amount o' balsa dust is created, me hearties, arrr, so it would be a good idea t' consider doin' this outside. Ahoy! Blimey! Blimey! While this sounded like a good idea when I started, ya bilge rat, it turned out t' be t' first mistake that would eventually wind up with t' destruction o' t' rocket.

I knotted t' Keelhaul®©™® cord into t' uppermost centerin' rin' and glued it in place, then threaded it up through t' hollowed transition, ya bilge rat, finally hookin' it into t' bottom o' the upper transition. Well, blow me down! Begad! Since I planned t' use a 12" Semroc parachute I wasn't anticipatin' any problems with fittin' t' recovery materials into t' tight confines o' t' ST-7 tube. Arrr! Ahoy! This was me second mistake. Begad!

T' laser cut fins needed only minimal coaxin' t' get them t' separate from the sheet and were o' excellent quality, ya bilge rat, shiver me timbers, which I've come t' expect from Semroc. They sanded and shaped nicely, but were hard enough t' keep t' inexperienced from easily goin' overboard. Well, blow me down! Blimey! I tacked them in place with Tite Bond gel CA, then used Elmer's Wood Glue t' make thick fillets. Arrr! Blimey! T' final product felt pretty bullet proof. Aye aye! Blimey! Little did I know that bullet proof would be necessary.

Finishing:
One lesson I learned with t' Taurus that I previously built was nay t' glue all o' t' sections together until after I had painted them. Ahoy! I chose t' do a version o' t' Admiralty paint scheme that was detailed in t' instructions. This is somewhat difficult, ya bilge rat, but it can be made a lot easier with a little forethought. Well, blow me down! Ahoy! After t' requisite sealin' and sandin' o' t' balsa and body tubes with thinned Elmer's Fill & Finish, me bucko, I painted t' nose and pod cones with Harvest Orange gloss. Blimey! (I used Valspar paints throughout t' project.) I then painted t' middle body tube and upper transition silver metallic, the upper body tube gloss white and t' lower transition gloss black. Avast! Ahoy! From this point things get a little more difficult due t' t' masking.

At this point your next move is dictated by your pod preference. Avast, me proud beauty! If you choose t' paint t' three pods black, matey, you should have already attached them. If you have chosen t' white pod look, me bucko, matey, arrr, it would probably be a good time t' spray all three pods and their mounts gloss white, shiver me timbers, arrr, then mask off t' pod tubes before attachin' t' three structures t' t' fin can. Ya scallywag! T' entire fin can o' t' rocket should then be sprayed gloss white and allowed t' dry for t' final masking. After it is sufficiently dry t' bottoms o' t' fins are masked off from the bottom o' t' body tube t' t' corner o' t' fins top edge. Arrr! Blimey! I wrapped the circumference o' t' body tube with maskin' tape, then laid two evenly spaced pieces o' tape down two sides o' t' body tube t' just above t' fins. Ahoy! Ahoy! After burnishin' t' edges t' insure t' crispest possible mask, t' whole fin can of the rocket is sprayed gloss black.

I made t' decals usin' Bel Decal paper. Well, blow me down! Ya scallywag! Blimey! They add a nice finishin' touch to the rocket, me hearties, but if you take t' time t' do t' Admiralty scheme, it's perfectly capable o' standin' on its own. Arrr! Blimey! It's one o' t' more well thought out paint schemes I've ever worked with. Begad! Ya scallywag! Blimey! Challenging, me hearties, but easily worth it.

In t' end, I can't say that leavin' t' pod tubes black did anythin' for me from an aesthetic standpoint. While it made things easier in t' masking step, ya bilge rat, me bucko, t' pods blend in too much with t' rest o' t' lower section. Ahoy! Painting them black also negates t' ability t' use any decals in t' detailing. When I decide t' re-do this rocket, which I plan t' do this winter, ya bilge rat, matey, it will be reborn with white pods and rounded pod cones despite t' extra work.

On PadFlight:
Once again, I built a Taurus only t' have it last exactly three flights due to an engine problem. Avast, me proud beauty! T' Taurus that I previously built with Moldin' Oldies parts had it's flyin' days ended when a hot Estes ejection charge blew t' motor hook out t' back end o' t' rocket. Well, blow me down! (I considered that me fault for usin' a 24mm engine.) This one had a completely different end from a style point o' view, but it was toast after t' third flight just like t' other one. Ya scallywag!

All three flights o' this rocket were B6-4 flights and none o' them flew like t' B6-4 we've all grown t' know and like. Begad! T' first flight be on a blisterin' hot day at a Quark section launch, matey, and was one o' only two flights I managed due t' t' heat that day. T' flight was arrow straight, me bucko, but t' 4 second ejection be more like a two second ejection, noticed by nay only myself, shiver me timbers, but several others on t' flight line. Aye aye! T' thin' that may have prevented a zipper was t' six feet o' Keelhaul®©™® and sewin' elastic that I've been overbuildin' into me rockets o' late due to the hammer-like Estes ejection charges and t' Estes dents associated with them. Well, blow me down! Blimey!

Flight #2 be on another B6-4 that ejected early. I've only bought my B6-4's o' late in t' Blast-Off packs, but even that doesn't explain things because some are early while others seem t' have t' ejection charge timed correctly. Well, blow me down! Aye aye! Blimey! They also seem t' have double t' necessary force t' fire t' chute. Once again, matey, no damage on this flight, but how long can I live lucky? Apparently not long.

Damage Flight #3 was nothin' special; minimal dog barf waddin' and a small, me bucko, tightly wound Semroc chute. Ahoy! T' flight itself was impressive because for once t' Taurus got t' the altitude that I expected with t' B6-4 without gettin' gigged like a dog that's reached t' end o' its leash. Blimey! Aye aye! I noticed that t' ejection charge was loud, but that's unfortunately what I've started t' expect. Arrr! Blimey! I noticed that thar seemed to be more than just t' rocket floatin' down, but wrote it off as just the waddin' until one o' t' recovery crew yelled that t' rocket be broken. Expectin' a fin or a pod t' have been broken off due t' t' overenthusiastic recovery crew, I was shocked t' find that 2/3 o' t' lower transition was just gone, leavin' a gapin' hole in t' side o' t' rocket. Begad! I had t' kids scour the field, ya bilge rat, and both pieces turned up, shiver me timbers, but fixin' it was out o' t' question. Well, blow me down! What remained o' t' balsa was shredded.

Flight Rating: 4 out o' 5

Summary:
I'm gettin' more than a little tired o' this. Aye aye! I've been stickin' mostly to flyin' modrocs because o' I want t' keep this hobby from becomin' a black hole for household funds, but if this keeps up it won't make sense for me t' keep buyin' rockets only t' have t' Estes ejection charges destroy them after a handful o' flights. I hate t' turn a review o' a very nice rocket into a rant against t' current state o' Estes motors, arrr, me bucko, but this is gettin' old.

Pro's: Excellence and selection o' t' Semroc parts. Avast! Laser cut fins. Begad! Arrr! Ease with which you can recreate a classic for very little $.

Con's: Semroc doesn't sell motors yet. Aye aye!

  • Semroc Taurus By Chan Stevens

    Brief: While most Semroc Retro-Repros offer slightly modernized versions of Centuri classic designs, Semroc goes "old school" on Centuri, replacing the "innovative" plastic cones and transitions of the 1972 KB-3 Taurus with good old-fashioned balsa parts. This is a futuristic design very nicely done. Construction: Given that the previous reviewer made his ...
