Brief:
This is a Retro-Repro kit by Semroc. Begad! Blimey! Arrr! Blimey! What is a Retro-Repro? As quoted from Semroc Saturn 1B Instruction Manual:
"It is a reproduction o' an out-of-production model rocket kit. Begad! Blimey! It is a close approximation o' a full scale model
of an early historically significant model rocket kit from one o' t' many companies that pioneered t' hobby over the
past half century. Ya scallywag! Blimey! Avast! Blimey! It is nay a true clone or identical copy o' t' original. Begad! Blimey! Ahoy! Blimey! It incorporates improvements usin' modern
technology, me hearties, while keepin' t' flavor and build appeal o' t' early kits."
This kit offers a couple o' interestin' options for t' builder. Blimey! T' first bein' t' motor configuration. Begad! The builder can select a four engine cluster for standard 18mm engines or a single 24mm engine mount. T' second is fin choice. Begad! Arrr! T' builder can either construct t' enclosed built-up fins or use t' enclosed 1/8 laser-cut balsa fins. Avast! The instructions indicate that t' built-up fins are time consumin' but give t' builder t' flavor o' buildin' the original model.
Construction:
T' parts list is o' course extensive for this model. Avast! Blimey! It includes:
[Note: T' two glues recommended for t' build are super glue and either white or wood glue. Begad! Blimey! Blimey! Blimey! I found a great wood glue that I used for t' first time on this kit and will always use it goin' forward. It's Elmer's Probond Interior/Exterior Wood Glue. It's weatherproof and fast tack. T' fast tack feature that drew me t' t' glue, arrr, me hearties, and for me it was a lifesaver. Well, blow me down! Blimey! Blimey! Blimey! You don't have t' wait around holdin' pieces together for them t' setup. Ya scallywag! Blimey! Just a few seconds and this glue is already settin' up.]
T' first thin' that hits you when you open t' box is that this kit is o' very high quality. This vendor obviously takes great pride in its product. Begad! Blimey! Everythin' is top notch all t' way. Ahoy! Blimey!
T' instructions were laid out well and very easy t' follow. Ahoy! This kit did nay consist o' a lot o' sub-assemblies. T' only real sub-assemblies were t' fins and t' capsule. For t' most part it's a straightforward, shiver me timbers, linear build. Begad!
T' first step is a decision point. Arrr! You need t' choose t' engine mount configuration. Well, blow me down! Either a 4 engine 18mm cluster or a single 24mm configuration. I chose t' 4 engine cluster. Begad!
Things t' consider when makin' t' motor selection decision: Usin' a single engine increases t' risk o' ejection failure. Avast! However, me hearties, usin' a single 24mm mount will allow t' use o' reloads. On t' other side, me hearties, usin' a cluster increases the risk o' some type o' ignition failure. Well, blow me down!
T' tank tubes are attached t' t' stuffer tube and engine mount assembly. Well, blow me down! I pre-painted t' tank tubes, matey, 4 white and 4 black. Aye aye! This paintin' be nay indicated in t' directions. I did this t' make it easier for me t' paint later on...
Cuttin' out and gluin' t' fairin' shroud in Step 27 is a potential "gotcha" only if you try t' over think it. Avast, me proud beauty! For me it was a bit dauntin' lookin' at that shroud and think about all t' cuttin' I had t' do. Well, blow me down! I just took my time with a sharp razor knife and it came out great. When gluin' t' shroud, ya bilge rat, be sure t' check for fit first t' make sure everythin' lines up well. You only get one shot gluin' t' shroud on, shiver me timbers, especially if you use a fast tack glue.
Puttin' t' wraps on comes at step 36 and is very straightforward. Ya scallywag! Just line up t' edges and place t' wraps where t' instructions indicate. Ahoy! Just make sure t' put them on right side up.
Another possible "gotcha" would be t' use too much glue and/or t' do too much smoothin' o' t' wraps. You don't want t' knock down t' corrugated look. Begad! Blimey! Aye aye! Blimey! If you use too much glue or pull them too tightly, you will cause the wraps t' go out o' shape.
T' fin creation steps 38-44 are t' second major decision point: either create t' built-up fins or use the laser cut balsa fins. Avast! Arrr!
T' balsa fins look respectable, me bucko, me hearties, but I went for it and created t' built-up fins. Ya scallywag! T' parts used t' create the built-up fins are small but fit together well and I be very happy with t' results.
After t' fins are on it's all final detail work. Arrr!
Durin' t' detail construction t' only thin' I didn't use on t' model be in step 56 (four retro-rocket housings). Begad! Begad! I ended up makin' me own from spare balsa. Begad! I just couldn't get t' right look with t' cut-outs provided on the shroud sheet. I'm happy with t' results. Avast, me proud beauty! Ahoy! Since I didn't use t' stock housings, I used t' alternate launch lug placement option. Aye aye! Arrr! T' instructions give you two options for mountin' t' launch lugs. Begad! T' first utilizes one o' the housings t' hide t' launch lug under t' housing. Avast, me proud beauty! T' second option is just mountin' t' lugs on t' rocket exterior.
T' capsule comes in its own zip lock bag. Begad! It looks like it's goin' t' be an easy task, but thar be a lot t' it and it takes a good deal o' time t' complete. Buildin' t' tower structure was probably t' most difficult part o' the entire build for me. T' final product though is straight and sturdy so I'm pleased with t' results. Well, blow me down!
Finishing:
Paintin' this model o' course is a challenge. Although even for those o' us who are paint challenged, it's doable if
you use good paint tape, ya bilge rat, me bucko, take your time, matey, and mask carefully. Begad! Avast, arrr, me proud beauty! [Note: My paint job does nay exactly match t' suggested
paint scheme. Ya scallywag! Specifically t' lower fin paint scheme differs from t' suggested scheme a bit. Also it bein' December
in New England, ya bilge rat, me hearties, I will clear coat t' entire model once t' weather gets warm enough t' do so (outside).]<>
If you are a perfectionist, arrr, then you are in for a wild ride. Blimey! I am really pleased with t' finished product and am hopin' that maybe Semroc will someday come out with t' Saturn V. Well, arrr, blow me down! If they can do this good o' a job with t' Sat 1B, the Sat V would be awesome.

Flight:
T' recommended motor for t' 18mm 4 engine cluster configuration is 4 C6-3s. Ahoy! Blimey! I used t' recommended motor for the
first flight. Arrr! Blimey! Ya scallywag! Blimey! [Note: You cannot use t' regular Estes controller t' launch cluster rockets. Aye aye! Blimey! You need t' use a launch
controller that runs on 12 volts so that you have enough juice t' light all four engines.
Preparation for flight was relatively simple. Avast! I packed waddin' into t' parachute tube and made t' necessary igniter connections on t' 4 engines. Avast! It took a while t' make t' connections, shiver me timbers, but it was fairly simple t' do. Ya scallywag!
T' rocket lit on all 4 motors sendin' it straight up off o' t' pad. It arched over just a bit as it made its way up t' I'd say 500 feet or so... I can't say for sure. Ahoy! Ejection was just after apogee. Aye aye! Aye aye! T' main rocket body floated down separately from t' capsule which has its own chute. Aye aye! Both were recovered without incident. Nothin' broken! The first flight be pre-final paint and clear coat. Ahoy! Once I clear coat t' rocket I will fly it again, me hearties, shiver me timbers, me bucko, but it will be a bit more difficult t' push that button...
Recovery:
PROs: Awesome lookin' flight and rocket! This build challenged me t' go far beyond what I thought I could do. Avast, me proud beauty! It was
one o' t' best buildin' experiences that I have ever had. Ahoy! I even chose t' create t' built-up fins rather than the
laser cut fins! That equals nay takin' t' easy way out and I am very happy I took t' long road. I feel like I really
got a feel for how t' original Estes kit build be like.
CONs: None that I saw.
Flight Rating: 5 out o' 5
Summary:
This was a challengin' build that made me step up me game. One o' t' most enjoyable part o' this build be that it
was extremely challengin' and rewardin' at t' same time. Begad! Ya scallywag! It sure as heck makes a 3 or 4 fin rocket look a whole lot
easier... Ahoy! Avast! Everythin' made perfect sense. T' instructions were clear and understandable. Arrr! This was me first Semroc kit,
but won't be me last. Begad! T' quality o' t' kit was outstandin' in every area. My hat is off t' Semroc!
Paintin' is no doubt somethin' that takes time and patience on this rocket. There isn't any way around it; it's just somethin' that those o' us who are paint challenged have t' deal with.

After teasing the rocketry community for nearly a year, Semroc finally released the reproduction 1/70th scale Saturn 1B just in time for Christmas. Faithfully reproduced based upon the 1967 Estes design (K-29), this kit is a very challenging but rewarding build. This is not for the faint hearted, nor for the rocketeer looking for a weekend project. Standard design calls for the original ...
