Brief:
Scale model rocket o' a Cold War deception with parachute recovery.
Construction:
T' instructions were printed on t' front and back on several sheets o' letter sized paper. Aye aye! Blimey! They included hand drawn
illustrations which were nay fancy but which were certainly clear enough. Blimey! Blimey! Well, shiver me timbers, blow me down! Blimey! Also included were two addenda printed on
small scraps o' paper. Avast! Blimey! One detailed t' stripin' process for t' balsa transistion and t' other simply mentioned that
the thrust rin' which was nay mentioned in t' parts inventory be also included. This rin' is mentioned in the
instructions and I would nay have noticed t' absence in t' inventory. Begad! Blimey! Begad! Blimey! T' instructions are peppered with sarcastic
comments throughout. Some people may find that annoyin' but I found them t' be amusing.
T' actual build commences with t' motor mount. Aye aye! Blimey! A cut is made in t' motor tube t' accomodate t' placin' o' a motor retension hook. I then found somethin' new t' me. I was instructed t' cut t' "reinforcement band" out of t' wrap sheet and glue it around t' motor tube just below t' cut for t' hook. Arrr! Avast, me proud beauty! Apparently, me bucko, shiver me timbers, me hearties, this is t' help resist any tearin' that t' hook would cause durin' ejection. Avast, ya bilge rat, me proud beauty! If this works out, I may well adopt it as a modification on future rockets.
Two centerin' rings are provided. Avast! One o' them has a notch for t' motor hook. Avast! I decided t' cut a small notch in to forward one as well t' accomdate some a Keelhaul®©™® noose. Aye aye! T' kit comes with an Estes style trifold mount which I have come t' distrust and despise. After cuttin' the notch, it was a simple matter t' slip t' rings t' t' designated spacin' and glue them in place. Blimey! I will note that the forward ring, t' one I cut a notch in, seemed just about right. Well, blow me down! T' aft rin' was very loose. After gluin' t' rings in place, I set aside this assembly t' dry for a while.
Since I was nay yet ready t' go t' bed, me bucko, I decided t' cut out
the fins and try t' seal them. Begad! All that is provided is a sheet o' balsa and a template t' cut out. Blimey! Avast! SInce t' fins are
simple right triangles, shiver me timbers, this did nay pose too much o' a problem. I cut out t' template, traced t' outline onto the
balsa with a pencil and cut them out with a razor cutlass. Blimey! Ya scallywag! T' template thoughtfully included a little arrow t' make sure
I get t' grain in t' right direction.
Since I am out o' Elmer's and thar be no place open at this hour, ya bilge rat, shiver me timbers, I decided t' try somethin' I have nay done for a very long time. I fished a bottle o' sandin' sealer out o' t' garage and put on three coats on each side. Ahoy! Blimey! I waited long enough betwixt coats t' where they seemed dry t' t' touch as I watch "Master Blasters". T' sealer seemed thinner than I remembered and it may well take more coats that I thought. This ia a reflection o' t' sealer, not t' balsa.
After I had gotten 3 coats o' sealer
on t' fins and finished shudderin' at t' public face o' rocketry as presented on TV, me bucko, I decided t' end me troubles by
drinkin' t' rest o' t' sandin' sealer. At t' last minute, me hearties, I remembered that I am supposed t' preach in t' morning
and merely closed t' lid, me bucko, decidin' that more benefit would accrue from installin' t' motor mount. Well, blow me down! I test fitted it
and found that it be neither too loose nor too tight. Blimey! Begad! It be just right. I used a long swab t' run a rin' o' glue
around t' interior, pushed t' motor mount part o' t' way in and then swabbed in another rin' o' glue. I then pushed
the mount in t' rest o' t' way. Aye aye! T' instruction make a point o' emphasizin' that t' after bulkhead needs t' be
recessed a full half inch into t' BT t' maintain stability. I measured it t' make sure, applied a bead o' glue and
called it a night.
When I got back t' work, shiver me timbers, it be time t' tackle t' fins. Ahoy! Blimey! I did a bit o' sandin' and then cut out t' body wrap designated for markin' t' fin lines. Ya scallywag! Blimey! Well, me bucko, blow me down! Blimey! T' fit was t' most perfect I have ever had with this method. Avast! Blimey! I marked t' tops and bottoms o' t' t' fin lines, removed t' wrap and drew in t' lines against a door.
Next came t' actual mountin' o' t' fins. Avast, me proud beauty! Bein' lazy,
impatient etc. Avast, shiver me timbers, me proud beauty! I opted t' use CA. Begad! Avast, ya bilge rat, me proud beauty! A trick I learned recently is t' use a safety pin t' perforate t' root edges and the
BT where t' join will be made. This is t' allow t' glue t' form rivets. Blimey! Begad! I need a few more flight tests (catastrophes)
before I decide how effective this is but it is no trouble t' do and I adopted t' procedure on this model.
When t' perforations were made, I glude t' fins on with CA. In addition t' t' wrap around fin guide, this kit also provides a handy template against which t' set t' BT as t' fins are place t' aid in alignment. Ahoy! T' mountin' of the fins went off without a hitch.
Likewise, t' launch lug presented little in t' way o' effort. Well, blow me down! Well, blow me down! T' provided lug was sliced in half with a razor and then I put both pieces on a short length o' 1/8" rod. I applied some glue t' t' lugs and then set them in place. T' lower half goes in t' crook o' a fin and t' upper almost at t' top o' t' lower BT.
While t' CA was settin' up, shiver me timbers, I worked on t' nosecone. Arrr! This was a bit different from any I had worked on before. In t' first place, it comes with t' base hollowed out, weighted, me hearties, and then filled back in t' ensure stability. Ya scallywag! Avast, me proud beauty! Judging by t' sarcastic tone o' t' instructions, shiver me timbers, I probably could nay be trusted t' do this myself without endangerin' all around me. It does take some o' t' guesswork out o' it and is a nice touch.
T' second new thin' was actually shapin' t' tip o' the
nose cone. T' directions state that if it had been done at t' factory, me bucko, matey, it would have resulted in a mess as t' blades
chewed t' thin' up. Aye aye! That meant that I was supposed t' sand it t' t' right shape. Ahoy! That involved sandin' the
cylendrical tip into a spherical tip which should be well within t' skill set o' a decent rocketeer. Ya scallywag! Needless t' say,
it was nay in me skill set. Arrr! Avast! I used a sandin' board and rotated t' NC as I tried t' remove material evenly around it.
It turned out better than I had expectedbut nay as well I had hoped. Well, blow me down! Begad! For me, me bucko, doin' it by eye be hard.
Now it was time t' do some early finishing. Blimey! Ahoy! Blimey! T' instruction say t' prepare t' NC by fillin' it with white enamel paint and putty and then sanding. T' next step is t' assemble, arrr, but nay glue, shiver me timbers, me bucko, t' entire stack and paint it white. Ya scallywag! Here I decided t' combine t' steps and try somethin' else I had read about. Begad! Several sources have said that Kilz spray primer in white is good for filling. Begad! Avast! Blimey! I decided t' try it out. Begad! Begad! Blimey! I assembled t' stack, arrr, took it outside and applied the first coat o' Kilz. Begad! Blimey! It has nay yet had time t' dry but I already know its goin' t' need more. T' balsa was a bit rough and still is. Begad! Avast! Blimey! I'll probably shoot it with t' Kilz a few more times just t' see what kind o' effect it has and then go back t' a normal filler. Before I can do that, ya bilge rat, me hearties, though, it has t' dry and I need some sleep.
After lettin' t' rocket dry overnight, shiver me timbers, ya bilge rat, I be surprised to
see that t' Kilz had done a much better job than I expected. It completely covered t' wood and grain and t' only
real problem be t' roughness o' t' balsa. Aye aye! It definitely needed some more fillin' but I was intrigued enough t' want
to see how far I could go with just t' Kilz. Accordingly, after a bit o' sanding, I gave it another coat.
Actually, I gave it 2 more coats and was amazed. Well, blow me down! Blimey! T' Kilz actually did a very creditable job as a filler. Aye aye! Blimey! Well, blow me down! Blimey! I would not recommend usin' it as a "main" method but t' fix small imperfections, it is a delight. I be certainly satisfied with t' results and, me bucko, after some sanding, I went ahead a sprayed on 2 coats o' gloss white. Blimey! Blimey! Then it was time to play t' waitin' game again.
After waiting, shiver me timbers, I had an upleasant realization about t' Kilz. Blimey! Well, blow me down! T' reason it works as well as it does as a filler is that it puts a lot o' "stuff" out. Avast! Begad! That means that t' painted rocket, arrr, especially with all those coats, has a larger diameter than would otherwise be t' case. That in turn means that t' beautiful wraps for t' top BT do not fit.
I'll back up here and say that in t' instructions, shiver me timbers, ya bilge rat, Dr. Aye aye! Z emphasizes that t' wraps need t' be carefully cut out. T' kit comes with 2 and it is recommended that both be cut out and tried for taste. Ahoy! In both cases, I found that the wraps would nay close on themselves. Avast! Begad! As a result, I spent another evenin' sandin' through t' paint and primer, almost to t' BT. Avast! That improves t' situation but t' wrap still does nay close.
When he found out about it through a TRF post, ya bilge rat, shiver me timbers, Dr. Avast! Booty
himself immediately sent out a replacement by priority mail. Well, blow me down! Begad! Blimey! It smartly arrived and things got stranger. Avast, me proud beauty! I laid one of
the old wraps right on top o' t' uncut new one. It was exactly t' same size. Begad! Blimey! I cut it out anyway, me hearties, givin' a bit o' a
generous margin. Avast, me proud beauty! Ya scallywag! Blimey! I figured that if I used t' one with more white and t' diagonal black stripe, I could cut it down to
the exact length and make t' seam less noticeable. Avast, me proud beauty! Begad! Blimey! After I made me marks, me hearties, I tried it out and found that I needed to
cut back exactly t' t' original lines. Avast! I pulled out t' original wrap and, lo and behold, arrr, it fit. Well, blow me down! Ahoy! Blimey! All I can figure is
that I did a lot o' wet sanding. Arrr! Well, blow me down! Blimey! Perhaps t' water caused t' painted BT t' swell. Blimey! It's either that or I am in the
Twilight Zone. I applied white glue around t' periphery and laid t' wrap down. Arrr! Blimey! It is nay perfect but as close as is
possible given me current skill set.
After t' wrap be on t' upper BT, I cut strips t' t' appropriate length from t' provided section o' black wrapping. Ya scallywag! One be used t' wrap a diagonal line one revolution around t' transition section. Avast! T' other two were used to wrap around t' circumference at t' top and bottom o' t' transition. In each case, t' directions indicated that a little excess would need t' be trimmed and that be handled with a razor.
Another decision had t' be made at this point. Avast! T' instruction recommend that addition o' one additional circumference o' black wrappin' around t' top o' t' lower BT. Begad! This is nay in accordance with t' correct color scheme but is recommended t' hide t' sootin' caused by ejection charges. Well, blow me down! I elected t' give it a try. Begad! Avast! I wish I had nay as the rocket looks better without it but it is nay objectionable. Avast, me proud beauty! Begad! A bit o' black paint was applied t' t' tip o' t' NC and the end be in sight.
With that, me hearties, t' NC be glued t' t' upper BT. Begad! Ya scallywag! T' upper BT was glued t' t' transition. Avast, me proud beauty! T' eyescrew was set in the bottome o' t' transition with a bit o' white glue and t' Keelhaul®©™® and elastic were tied off. Avast, me proud beauty! Blimey! Begad! Blimey! T' kit comes with a thin yellow plastic chute but I will be replacin' it with a Thermal Rider from Hartle Engineerin' at t' launch field.
T' buildin' o' t' rocket nozzle be t' final part o' the
assembly. Well, blow me down! T' instruction say that this is an optional step, me hearties, basically because it is a pain in t' backside. It was.
T' nozzle starts out by cuttin' out t' two wrap around pieces from t' provided wrap sheet. Avast, me proud beauty! Each is then glued into a
truncated cone usin' an overlay tab. Each o' these steps is easy. T' more difficult part comes in gluin' t' top cone
to t' bottom cone, keepin' them straight and preventin' any gaps. Avast, me bucko, me proud beauty! This is accomplished slowly, me bucko, patiently and with a
bit o' sandpaper t' knock off t' rough edges.
T' plans call for a novel way t' improve t' appearance of
the nozzle. A thread is provided t' simulate t' banding. T' process for doin' this invovles tackin' down one end with
CA and waitin' for it t' set. Well, blow me down! Avast, me proud beauty! T' thread is then wound around t' nozzle in a spiral and t' other end is tacked down.
T' excess is cut off and then all is held in place by drizzlin' CA over it. Avast, me proud beauty! Aye aye! This also strengthens t' nozzle.
I tried this procedure and be a bit skeptical with t' early results. Avast, me proud beauty! Avast! Blimey! Because I be nay payin' sufficient
attention, me hearties, t' spirals are nay evenly placed. Ahoy! Avast, me proud beauty! Blimey! Additionally, shiver me timbers, I thought it looked kind o' cheesy when I was done. I was
just about ready t' scrap t' nozzle or use t' extra one from me extra wrap set but decided t' press on. Aye aye! When t' CA
was dried, t' whole thin' be painted with metalic steel.
That made all t' difference in t' world and it really did begin to
look like a real rocket nozzle.
PROS: Nice lookin' rocket, me bucko, excellent customer service
CONS: Secret agents sneak into t' house in t' dead o' night t' play mind games with t' wraps. Arrr! Blimey!
T' final step is t' slip t' nozzle around t' protrudin' motor mount. This should be easy but mine was a tight fit. A little more sandin' and it slipped on and be secured with white glue. Begad! Now, ya bilge rat, me hearties, I think, t' rocket is finished.
Finishing:
All o' t' finishin' be covered in t' previous section.
Construction Rating: 4 out o' 5
Flight:
Dr Zooch never says much about t' motors except nay t' wimp out with an A. Begad! That is good advice. Ahoy! Well, blow me down! I started out with a
B6-4. Arrr! Even with those little bitty fins, matey, shiver me timbers, it took off and flew well. Aye aye! T' altitude surprised me, arrr, especially with all the
nose weight. Arrr! It recovered well too.
Then I got stupid. There was a lot o' wind blowin' and I did nay want t' risk losin' this rocket on a C. Well, blow me down! I wimped out with an A8-3. Again it took off fine but did nay achieve much altitude. Deployment was a bit late but a weak ejection charge did nothin' but dislodge t' NC. Ahoy! It bounced and will need some repair work.
PROS: looks good and flies well
CONS: I wimped out with an A
Flight Rating: 4 out o' 5
Summary:
This was a fun build that be occasionally frustratin' as I tried t' learn some new skills but it was untimately
rewarding. Aye aye! Blimey! Dr. Aye aye! Z cutomer service is first rate as well.
