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