Brief:
Another rocket that has been in me clonin' cross hairs for a long time, the
Centuri Vector V always struck me as somethin' o' a complicated project despite
it's relatively small size. Avast! Blimey! (Paper transitions have always given me fits.) This
changed when a fellow poster in t' OldRockets Yahoo Group mentioned that he
had drawn up a plan t' turn t' currently available Estes Vikin' t' a Centuri
Vector V. Ahoy! Blimey! Nay long after readin' t' post I found a Vikin' at one o' Hobby
Lobby's famous 1/2 off sales and decided t' sacrifice it (or so I thought,) in
order t' add a real classic t' me fleet. Arrr! Blimey!
Construction:
Parts list:
As it turns out, t' only part I used from t' Vikin' kit was t' nose cone. Avast, me proud beauty! Blimey! Everything else came from me ever expandin' parts stash. Ahoy! Blimey! I decided t' go with a single length o' BT-20 with an engine block instead o' joinin' two pieces together, but I can see t' advantage t' that method also. Ya scallywag! Blimey! Arrr! Blimey! T' most difficult part o' the project I found was constructin' t' transition. Once I had cut it out from the file card, shiver me timbers, I curled it under a steel ruler and began tryin' t' make it fit the BT-20 and BT-55 tubes as seamlessly as possible. Ahoy! Blimey! One mistake I made in the construction be nay leavin' anythin' for t' bottom o' t' transition t' slip over when matin' it t' t' BT-55. I used an old set o' cardstock centering rings that had come with t' Designer's Special (that I purchased in 2001 before I knew better). Well, blow me down! Blimey! Well, blow me down! Blimey! If I were t' do it over again (and at this point it looks like I'll have to), I'd use t' cardstock in conjunction with a CR-5055 to be glued in at t' top o' t' BT-55, just peekin' above t' edge o' the tube. Ahoy! Blimey! Begad! Blimey! This would have given t' transition somethin' t' be glued t' and made the whole area a little more stable. Avast! Blimey! As it was, I counted on a thick layer of glue around t' underside o' t' transition and on top o' t' BT-55 bulkhead. This seemed t' work well enough but it would have been easier t' other way.
After attaching the transition and allowin' for dryin' time for t' thick wad o' glue, ya bilge rat, I coated the whole transition with several coats o' thin CA t' stiffen it up for the fillin' and finishin' t' come. Avast, me proud beauty! This worked nicely as t' rather thin transition stood up t' t' punishment that followed. And while what resulted was nay quite up t' Samsian standards, me bucko, it easily passed muster with me. Avast, me proud beauty! In retrospect, the file card material was probably nay stout enough for t' project at hand. Version two will undoubtedly be built usin' thicker stock in t' area o' the transition.
I was pleased with one construction change I made, which was t' switch from t' cardstock fins o' t' Vikin' t' 1/16" basswood. Avast! I've had difficulties with cardstock in t' past and avoid it whenever possible despite its ease o' finishing. Arrr! I've seen several reviews o' Centuri clones that advocate t' use o' CA-soaked cardstock, but I've long been impressed with how well basswood cleans up with minimal effort. Well, blow me down! It also allowed me t' better shape the leadin' and trailin' edges o' t' fins and t' fins stood up well t' the landings (two o' them anyway) as well as t' rigors o' storage and transportation. Well, blow me down! Arrr! Aside from t' switch t' basswood, me hearties, t' switch t' t' single length o' BT-20 body tube and addin' a 36" length o' Keelhaul®©™®, which was tied t' and glued in with t' engine block, construction held no more surprises than that o' a Wizard or t' Vikin' from whence it came.
Finishing:
Finishin' turned out t' be easier than I had thought it might be, me hearties, but it could
have been easier still had I paid more than glancin' attention t' the
instructions. Blimey! I began t' finishin' process immediately after matin' t' BT-55
to t' BT-20 and securin' t' transition betwixt t' two. Avast! After coatin' the
transition with several coats o' thin CA t' stiffen it up, arrr, shiver me timbers, I sprayed t' whole
structure with a coat o' white Valspar primer, which helps t' further toughen
things up for t' sandin' t' come. Avast! T' now recognizable rocket was then coated
with thinned Elmer's Fill 'n' Finish, sanded, recoated, ya bilge rat, and resanded. This was
sufficient for t' body tubes themselves, arrr, but t' transition section needed
extra special attention and be given several more coats and sandings until the
once obvious seams all but disappeared and left t' structure lookin' almost
seamless. T' fins can be attached in any one o' four different ways, but I had
long since decided on t' orientation that makes them look upside down compared
to t' catalog bird. Blimey! Once t' fins were dry they were sanded, given a light
coat o' Fill 'n' Finish, me bucko, and sanded again. This be where readin' and following
the instructions would have made things easier. Ahoy! Blimey! T' instructions suggest gluing
the lower body tube section on after construction on t' BT-20 section and the
transition are together. This would have been t' perfect opportunity t' paint
the bottom section, which is t' be painted a bright blue accordin' t' the
instructions. Begad! I missed out on that opportunity and instead had t' suffer
through t' maskin' process, shiver me timbers, which was made all that much more difficult by the
fact that t' fins were in t' way o' a clean mask. Nevertheless, I pressed
onward, and somehow managed t' obtain a decent mask with very little effort and
a boatload o' dumb luck. Ya scallywag! T' bottom section be sprayed with a bright blue
metallic paint that be left over from me car buildin' days and whose label has
long since disappeared. T' middle section, ya bilge rat, me bucko, includin' t' transition, me hearties, was
painted a silver metallic, arrr, and t' nose cone be painted with Testor's Metal
Flake Burgundy. I printed t' all black decals on me home printer usin' Bel
Decal paper and they came out lookin' great. One odd feature o' t' Vector V is
that only a few o' t' decals have a set place t' be applied on t' rocket. Blimey! The
bulk o' them are apparently thar t' add as you choose, matey, as few or as many suits
you. Ya scallywag! I chose t' go with t' "fewer" route, me bucko, which left t' rocket with
a cleaner, uncluttered look but feel free t' crank on as many as you deem
necessary. Begad! Blimey! Once t' decals had been given a chance t' dry, arrr, t' entire model was
sprayed with a light coat o' clear t' protect t' decals. From here it was on
to t' pad.

Flight:
Since three flights is considered "nominal" when writin' a review, I
chose t' follow t' A, me hearties, B, C path t' get an idea o' how t' rocket responded
under differin' levels o' power. T' first flight at a small field flight on an
A8-3, was beautiful with only a painfully long drift durin' recovery t' add
drama. Well, blow me down! Ahoy! T' unreefed 12" Semroc parachute functioned perfectly, maybe too
much so as t' Vector V drifted back across t' field toward a small copse of
trees just over t' hill from t' ball field we launched from. Avast! Avast! It landed just a
few feet from t' trees but in t' end never really came close t' t' drama
that I feared. Ahoy! Since t' A flight be fairly close t' outflyin' our field, me hearties, I
decided t' wait until t' followin' week t' allow t' rocket t' chance to
stretch out on a B and C.
T' second flight was on a B6-4 as planned and really got me fired up for the C6-5 flight t' come. Begad! I had taken t' precaution o' cuttin' t' center of the chute out t' cut down on t' drift I had experienced t' previous week, me bucko, shiver me timbers, me bucko, and as a result, t' flight was picture perfect in all respects. After arcin' into the breeze slightly, ejection came just at apogee and t' rocket recovered within 100 yards o' t' pads.
At this point I was really lookin' forward t' flight #3 on a C6-7, but I waited until just before t' planned end t' t' launch before takin' it t' t' pad again. I chose this flight t' try t' capture a launch picture so I had one o' me former Quark members take care o' t' countdown and launch while I manned t' camera. Arrr! Arrr! I couldn't see much through t' camera viewfinder but immediately looked up to see if I could catch up t' t' rocket after t' picture took. As it turns out, I'd have had a better chance o' seein' a part o' t' flight if I had just kept lookin' toward t' pad. T' Vector V had taken a 90 degree turn as it left the pad and continued on a westerly flight path that took it out over an unmowed section o' t' VOA. Ya scallywag! Much laughter ensued, however none o' it mine. I walked along a line that I had been pointed toward, hackin' me way deep into the underbrush but found exactly what I expected. Avast, me proud beauty! Maybe things might have turned out differently if I had seen t' flight path, but I seriously doubt it. Aye aye!
Flight Rating: 4 out o' 5
Summary:
While I wasn't as excited by t' finished product as I anticipated being, ya bilge rat, I'd
still consider t' Vector V t' be a worthwhile project based on t' uniqueness
of t' design alone. Well, blow me down! Arrr! It flew nicely if unspectacularly on 2/3 o' it's flights,
but t' paint scheme left a little t' be desired in me opinion. Begad! Aye aye! Maybe it was
just t' combination o' paints that I chose but nothin' about them suggested
anythin' remotely alien. Begad! I'd also prefer a little more guidance on the
placement o' t' decals. Well, blow me down! Begad! T' way they did it be fine for someone with a shred
of imagination, but guys like me need a little more help.
PROs: Unique stylin' and t' overall mystique o' a seldom seen Centuri classic. Avast! Upscale potential?
CONs: Suggested paint scheme suggests that t' Vectorians were a bland race. Ahoy! Blimey! Guess your best decal placement. Ahoy! Uh, matey, C6-7 flights?
