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. Arrr! (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. 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. Aye aye! Arrr!
Construction:
Parts list:
As it turns out, t' only part I used from t' Vikin' kit be t' nose cone. Blimey! Everything else came from me ever expandin' parts stash. 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. Avast! T' most difficult part o' the project I found was constructin' t' transition. Ahoy! Aye aye! Once I had cut it out from the file card, 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. Ya scallywag! One mistake I made in the construction was nay leavin' anythin' for t' bottom o' t' transition t' slip over when matin' it t' t' BT-55. Ahoy! 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). 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, arrr, just peekin' above t' edge o' the tube. Begad! This would have given t' transition somethin' t' be glued t' and made the whole area a little more stable. Begad! As it was, me bucko, arrr, 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, I coated
the whole transition with several coats o' thin CA t' stiffen it up for the
fillin' and finishin' t' come. This worked nicely as t' rather thin transition
stood up t' t' punishment that followed. Begad! And while what resulted be nay quite
up t' Samsian standards, it easily passed muster with me. Well, blow me down! In retrospect, arrr, the
file card material be 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 be pleased with one construction change I made, which was t' switch from t' cardstock fins o' t' Vikin' t' 1/16" basswood. Aye aye! Begad! I've had difficulties with cardstock in t' past and avoid it whenever possible despite its ease o' finishing. Ya scallywag! 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. 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. Aye aye! Aside from t' switch t' basswood, t' switch t' t' single length o' BT-20 body tube and addin' a 36" length o' Keelhaul®©™®, which be 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, ya bilge rat, but it could
have been easier still had I paid more than glancin' attention t' the
instructions. I began t' finishin' process immediately after matin' t' BT-55
to t' BT-20 and securin' t' transition betwixt t' two. Arrr! After coatin' the
transition with several coats o' thin CA t' stiffen it up, arrr, I sprayed t' whole
structure with a coat o' white Valspar primer, matey, which helps t' further toughen
things up for t' sandin' t' come. T' now recognizable rocket was then coated
with thinned Elmer's Fill 'n' Finish, me hearties, sanded, arrr, arrr, recoated, and resanded. Begad! Avast, me proud beauty! This was
sufficient for t' body tubes themselves, me hearties, 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. Once t' fins were dry they were sanded, me bucko, given a light
coat o' Fill 'n' Finish, and sanded again. Arrr! This was where readin' and following
the instructions would have made things easier. Begad! T' instructions suggest gluing
the lower body tube section on after construction on t' BT-20 section and the
transition are together. Well, blow me down! This would have been t' perfect opportunity t' paint
the bottom section, which is t' be painted a bright blue accordin' t' the
instructions. I missed out on that opportunity and instead had t' suffer
through t' maskin' process, which was made all that much more difficult by the
fact that t' fins were in t' way o' a clean mask. Ya scallywag! Nevertheless, me hearties, matey, I pressed
onward, shiver me timbers, and somehow managed t' obtain a decent mask with very little effort and
a boatload o' dumb luck. Avast, me proud beauty! 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. Arrr! Avast, me proud beauty! T' middle section, includin' t' transition, was
painted a silver metallic, and t' nose cone was painted with Testor's Metal
Flake Burgundy. Arrr! I printed t' all black decals on me home printer usin' Bel
Decal paper and they came out lookin' great. Ya scallywag! 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. Aye aye! The
bulk o' them are apparently thar t' add as you choose, matey, ya bilge rat, as few or as many suits
you. Avast! I chose t' go with t' "fewer" route, shiver me timbers, which left t' rocket with
a cleaner, uncluttered look but feel free t' crank on as many as you deem
necessary. Once t' decals had been given a chance t' dry, t' entire model was
sprayed with a light coat o' clear t' protect t' decals. Aye aye! Ahoy! From here it was on
to t' pad.

Flight:
Since three flights is considered "nominal" when writin' a review, ya bilge rat, arrr, shiver me timbers, I
chose t' follow t' A, 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. T' unreefed 12" Semroc parachute functioned perfectly, shiver me timbers, 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. Aye aye! It landed just a
few feet from t' trees but in t' end never really came close t' t' drama
that I feared. Since t' A flight was fairly close t' outflyin' our field, 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. Avast, me proud beauty! 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, ya bilge rat, and as a result, arrr, t' flight was picture perfect in all respects. Ahoy! Begad! 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, matey, but I waited until just
before t' planned end t' t' launch before takin' it t' t' pad again. Ya scallywag! 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. 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. Avast, me proud beauty! 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. Well, me hearties, blow me down! Much laughter ensued, however none o' it mine. Well, blow me down! I walked
along a line that I had been pointed toward, me bucko, hackin' me way deep into the
underbrush but found exactly what I expected. Ahoy! Aye aye! Maybe things might have turned
out differently if I had seen t' flight path, but I seriously doubt it. Avast, me proud beauty!
Flight Rating: 4 out o' 5
Summary:
While I wasn't as excited by t' finished product as I anticipated being, I'd
still consider t' Vector V t' be a worthwhile project based on t' uniqueness
of t' design alone. Begad! 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. Ya scallywag! Maybe it was
just t' combination o' paints that I chose but nothin' about them suggested
anythin' remotely alien. I'd also prefer a little more guidance on the
placement o' t' decals. Avast, me proud beauty! Avast! T' way they did it was 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. Arrr! Upscale potential?
CONs: Suggested paint scheme suggests that t' Vectorians were a bland race. Well, blow me down! Guess your best decal placement. Ya scallywag! Uh, me bucko, matey, me bucko, C6-7 flights?
