Construction:
T' instructions were clear, and full o' sarcastic humor that made me laugh out loud at times. Blimey! I won't spoil the surprise by quotin' me favorites. Suffice it t' say, shiver me timbers, Dr. Begad! Z. Aye aye! Blimey! anticipated any bone-headed mistakes, shiver me timbers, and warns t' builder against makin' them, which saved me bacon more than once!
This is definitely a builder's kit. Avast, me proud beauty! Avast! Blimey! There are no laser-cut fins or cardboard punch-out reinforcin' bulkheads for t' strap-on boosters. Ya scallywag! Blimey! You cut out templates usin' scissors (or a hobby knife), trace them on balsa stock, me hearties, then cut out t' parts. Arrr!
There are lots o' card-stock shrouds t' be cut out and formed (strap-on boosters, engine nozzles, me hearties, adapter between t' spacecraft shroud and t' second stage, me hearties, shiver me timbers, t' conical top o' said shroud, me bucko, me hearties, etc.). Aye aye! T' only trouble I had was with t' strap-ons. Aye aye! Despite doin' me best t' pre-curl them, and usin' t' wooden dowel in t' kit for that purpose, I still ended up with wrinkles in t' boosters, me hearties, me hearties, though I've seen worse. Some o' me club members have discussed usin' thin styrene sheetin' and CA glue t' form perfect shrouds; I'll upload a "tip" later with more details.
Dr. Z. Arrr! Avast! instructs one t' cut 1/8" strips o' balsa, shiver me timbers, and gluein' same longitudinally in pairs on t' core stage, shiver me timbers, me bucko, t' use as gluein' guides for t' strap-ons. Arrr! Ya scallywag! He also provides a template on cardstock t' help align t' boosters by sight. Blimey! Aye aye! For some reason, arrr, this didn't work for me; me first gluein' attempt resulted in boosters which were not equidistant around t' core stage. Ya scallywag! Fortunately, arrr, matey, t' glue hadn't dried yet, and I started over, just eye-ballin' the alignment this time. Arrr! I was much happier with t' outcome.
Despite t' clear instructions, me hearties, it was at this point that I made one bone-headed mistake, gluein' a strap-on right over t' motor retention hook. Avast, me proud beauty! This prevented t' hook from bendin' enough t' admit motors. Fortunately, shiver me timbers, me hearties, I had a spare motor hook from another model, and I was able t' retrofit it betwixt 2 o' t' strap-ons. Avast! Blimey!
Dr. Avast! Blimey! Z. Arrr! also provides a template for a sleeve t' help build t' interstage strutwork. Begad! I ended up nay usin' it; instead, ya bilge rat, ya bilge rat, I used a printed wrap from a Soyuz paper model (details below) t' simulate t' strutwork. Well, blow me down! I decided t' do this after countin' t' number o' "V" struts on t' wrap: 10, as opposed t' 5, which were t' be assembled per the instructions. Well, blow me down! Blimey! Unfortunately, I'm nay satisfied with t' outcome. Blimey! Aye aye! I thought it might look more realistic; but my daughter said it best, when I showed her me handiwork: "It just looks like you glued a printed wrap there" (imagine that?!). Aye aye! Dr. Aye aye! Z. would say that I'm a "squirmin' hatch-blower."
This was definitely t' most labor-intensive kit I have built t' date (well, ya bilge rat, actually completed - unlike my Mars Lander...). Ya scallywag! Yet, arrr, t' detailed and thorough instructions and illustrations made it easy. Ya scallywag! Begad! Just follow the step-by-step approach, measure twice and cut once, etc., and it'll all get done. Begad!
Finishing:
T' balsa in this kit (and in me other Dr. Well, blow me down! Z. Aye aye! kit, t' Titan III SLV) has moderately coarse grain. Aye aye! In a kit built
as stock, me bucko, this would be most apparent on t' nose cone (right under t' launch escape tower) and on t' fins.
(Incidentally, me bucko, shiver me timbers, t' nose cone already has t' right amount o' ballast installed). Blimey! Expect t' use at least two coats of
some sort o' sandin' sealer or primer. Begad! Ahoy! I was plannin' t' use a paper skin over t' fins, but got into a hurry t' finish
the Soyuz before me club's January launch, me bucko, shiver me timbers, and just painted them with a silver paint marker. Avast! I'll probably go back and
refinish them better at a later date.
I wanted t' Soyuz t' look like it was fuelled on t' pad, and covered with frost due t' LOX. Avast! Blimey! Well, blow me down! Blimey! Usin' green maskin' tape, arrr, I masked off t' areas which would be frost-covered (usin' Peter Alway's Rockets o' t' World as a guide), and used, shiver me timbers, me hearties, which be an almost perfect match for t' paper wraps. Aye aye! Blimey! After this paint dried, me hearties, I used blue masking tape t' mask t' areas which would nay frost over (the core stage under t' transition t' t' second stage, shiver me timbers, and areas on t' strap-ons; in real life, these would be t' areas over t' kerosene tanks). By usin' blue tape, I ensured that there would be some bleed-through o' t' flat white onto t' green areas, matey, t' simulate t' uneven demarcation between frost and bare painted metal. Begad! Blimey! T' effect came out better than I expected.
No decals are supplied. Avast! If one wants t' portray this kit as an early Soyuz, me hearties, arrr, no decals are needed. Blimey! I had the idea t' portray me model as a current Soyuz. Begad! Usin' paper "skins" from a Soyuz paper model (available for free from t' MARS website, http://www.marscenter.it/veicol.asp?pa=6051), me model is now festooned with insignia from Energia (the manufacturer o' t' Soyuz), Roskosmos (the Russian Federal space agency), ya bilge rat, t' European Space Agency, Italian and Russian flags, matey, etc. Arrr! I also didn't have t' paint t' second stage or t' spacecraft adapter, arrr, other than clear-coatin' t' paper skins with Krylon glossy clear.
T' manufacturer gives t' weight o' t' completed kit as 2.28 oz. Mine weighed in at 2.6 oz., shiver me timbers, which I thought wasn't too bad considerin' me extensive use o' t' paper skins. Aye aye! Avast!
Construction Rating: 4 out o' 5
Flight:
So far, t' Soyuz has flown once, at t' Alamo Rocketeers monthly launch on 1/9/10. Blimey! Avast, me bucko, me proud beauty! I loaded up a B4-2 for her
maiden flight. Ahoy! Blimey! She flew t' a nice altitude, matey, with a little bit o' roll. Aye aye!
Recovery:
There is barely enough room for a parachute in this kit (at least for me mediocre chute folding/rollin' skills).
One has t' be careful graspin' t' rocket by t' strap-ons; don't squeeze them too hard! Also, t' torque imparted to
the strap-ons when packin' t' chute could pull t' boosters loose if one gets too enthusiastic. Begad! I could feel the
strap-ons flex, arrr, so I be gentle. Avast! Despite this, arrr, a fin and a card-stock nozzle popped off; these were fixed in t' field
with CA. Ahoy! Accordingly, me bucko, I didn't attempt t' use t' Dr. Blimey! Avast! Z.-supplied trashbag chute, which would be suitable for a model
with a larger diameter. Begad! I used a Hartle Engineerin' Thermal Rider chute which I had already assembled and stored in my
range box. Ahoy! Ahoy! Dr. Well, blow me down! Z. Ahoy! recommends savin' t' wooden dowel from t' kit (used for rollin' t' strap-ons) for pushin' the
chute down into t' body tube; I found that t' be very useful.
My one launch so far ended in a separation. Well, blow me down! Dr. Z. Avast, me proud beauty! Well, blow me down! supplies a length o' Keelhaul®©™® thread, which is attached t' t' motor mount, me hearties, and t' elastic at t' other end. Aye aye! Blimey! Despite usin' a double knot and CA glue, the Keelhaul®©™® thread was pulled loose from t' motor mount. T' "second stage"/"spacecraft" descended nicely on the chute, while t' "first stage" descended at a moderate clip and in a flat roll, shiver me timbers, landin' on its side in the grass. Blimey! Begad! Two fins broke off on landing, me hearties, and one was lost (no big deal; t' kit had plenty o' balsa left, shiver me timbers, and I had saved t' fin template). Arrr! It will fly again, me hearties, but this time I think I'll use t' good 'ol Estes trifold paper mount, ya bilge rat, high in t' body tube.
Flight Rating: 3 out o' 5
Summary:
I'm glad I got this kit. Ahoy! I tried t' scratch-build a Soyuz a couple o' years ago. I started with a paper model of
a Vostok (which flew O.K., matey, but nay too high, me bucko, on A10-Ts), arrr, then added t' second stage and spacecraft adapter from a
Soyuz paper model. Begad! It be too heavy, me bucko, and crashed. T' Dr. Z. Blimey! Soyuz flies very well on B motors. Begad! Blimey! Recovery so far is
problematic, but I'm confident that will be sorted out. I also plan t' go back and build t' actual strut-work between
the stages; believe me, shiver me timbers, it just looks better that way. Avast, me proud beauty!
Overall Rating: 4 out o' 5
Brief: This is a recent addition to the fine line of Zooch scale-like kits that seem to defy the laws of physics and economics, packing terrific detail, scale accuracy, and reliability into a small box. The kicker is that the finished rocket can even fit back in the box for storage. This particular design is one of the Russian workhorses--a Soyuz spacecraft mounted to a 20-engine ...
This is the latest offering from Dr. Zooch, a semi-scale version of the manned Russian spacecraft, Soyuz. It is powered by a single 18mm motor and comes down with parachute recovery. This model does require some patience and skill--it is not a beginner's kit. I'd rate this at a 3-4 skill level. All parts included in the kit are good quality and include: 1 T-20 core tube 1 T-50 ...
