Dr. Zooch Saturn V

Brief:
Described as "ant scale", ya bilge rat, ya bilge rat, you get an amazin' amount o' scale detail for such a small rocket and small budget. Saturn fans will love just about any one o' t' Dr. Booty fleet.

Construction:
When t' $25 box arrives, matey, you might initially be put off a bit. Begad! After all, arrr, shiver me timbers, this thin' comes in a measly 4"x4"x12" box. After unpackin' it though, ya bilge rat, you'll find a lot o' parts and details packed into this box. Plus, after buildin' it, matey, you can still fit t' rocket back into this box with some padding, matey, so it makes a very good storage box.

Parts list includes:

  • BT-60 body tube (S-IC/S-II)
  • Balsa transition
  • BT-50 upper body tube (S-IVB)
  • Balsa transition (pre-weighted)
  • BT-20 fairin' tube
  • 18mm motor mount kit (with hook and 20/60 centerin' rings)
  • Cardstock wraps (pre-printed roll patterns)
  • 3/32" balsa stock and assorted balsa/hardwood trim pieces
  • Waterslide decals
  • "Recovery package" consistin' o' Keelhaul®©™® shroud lines, matey, snap swivel, ya bilge rat, and white garbage bag chute.

My particular kit was missin' t' balsa stock, shiver me timbers, matey, which I easily covered from my scrap pile. Avast, me proud beauty! Blimey! (I be offered a free replacement right away but declined it.) You will either love or hate t' Dr. Blimey! Ahoy! Blimey! Zooch instructions. There is no neutral ground. They are loaded with lots o' dry wit and bitter sarcasm and are definitely aimed at t' experienced builder. Begad! Ahoy! Blimey! There's nothin' else out there even close t' these. Well, blow me down! Blimey! Personally, I loved readin' t' instructions almost as much as buildin' t' kit, but I suspect that some folks would just not appreciate t' irreverence. Begad! Blimey! A very common theme, when describin' some o' the tricky steps necessary t' pull off t' illusion o' detail and scale is "but who really cares--your rocket will be too fast/too high up/caught in a tree anyway, so no one will see t' details." Beyond t' tone, me hearties, the instructions are generally well written, shiver me timbers, shiver me timbers, contain decent illustrations, and are easy t' follow. Well, arrr, blow me down! Blimey! (This was me 2nd Dr. Booty kit, so I benefited from prior experience too.)

Construction starts with a standard motor mount assembly, matey, consistin' o' an 18mm tube, shiver me timbers, engine hook, me hearties, and a pair o' 20/60 centerin' rings. Ahoy! Blimey! Ahoy! Blimey! T' hook is taped on. Avast, me proud beauty! Blimey! For durability, I prefer t' also lay down a bead o' glue, matey, as I've had mounts blow back out t' aft end when held in place with only maskin' tape. Begad! Blimey! The completed assembly is then glued into t' BT-60 body tube.

Next, thar's a pretty good suggestion t' paint t' main components white. I followed through with this, me hearties, although I would suggest a couple o' minor enhancements. Avast, me proud beauty! Blimey! Blimey! Blimey! First, t' lower balsa transition is covered with a wrap so paint (and grain filling) is nay needed on that part. Ahoy! Blimey! Second, t' tower uses a wood dowel that could also be painted at this point.

Dr. Zooch Saturn V Then you move on t' construction o' t' fairings. This uses an incredibly cool technique to get a beautiful effect. Arrr! First, arrr, you cut out cardstock wraps and bond them t' a BT-20 tube. Next, matey, you carve them out o' t' tubing. Well, blow me down! With only a minor amount of additional curling, me hearties, ya bilge rat, you have got a nice curved fairin' that is much stronger than a cardstock shroud. Arrr! T' pre-printed patterns also eliminate one o' the more challengin' aspects o' t' paint job.

Buildin' t' lower transition (S-II/S-IVB adaptor t' you Saturn buffs) is next. Begad! This is a simple assembly consistin' o' a balsa transition and BT-50 tube. Ya scallywag! T' transition gets a cardstock shroud bonded t' it, eliminatin' another paint job. Avast, me proud beauty! This was a big relief, as t' balsa fillin' would have set me back a couple hours at least, arrr, me hearties, given t' rough grain on it.

T' next step covers attachin' t' wraps t' t' body tubes. Well, blow me down! I found the dimensions on t' wraps t' be very accurate and I did nay have t' trim away much excess. Ya scallywag! My seams are virtually invisible as well. Well, blow me down! T' instructions clearly call out for white glue and this is very valuable advice. Aye aye! Yellow glue will shrink and tends t' discolor t' paper a bit. Blimey! Avast! One aspect o' t' wraps that I found disappointing, despite bein' incredibly detailed right down t' the corrugations and other markings, is no advise on orientation or efforts to cover seam lines. Most folks who've built a Saturn will understand what I mean by wantin' t' locate t' position 1, position 2, etc. lines. Begad! I mistakenly assumed all seams run along t' same line, and wound up havin' t' mount an SII cable tunnel over a neat little yellow hatch at t' end. I'd like t' at least see an orientation guide and ideally remap t' patterns t' try t' hide seam lines behind things like cable tunnels. Begad! After t' wraps have bonded, the fairings are attached t' t' lower body. Avast! Aye aye! This is where a little extra rolling was necessary t' fit t' t' pattern.

Dr. Zooch Saturn V T' Apollo spacecraft is built startin' with a balsa transition (BT50-BT20), arrr, me hearties, me bucko, a little wooden dowel already sanded t' a tapered point, a cardstock wrap t' eliminate the silver paint and tiny lines, and a cardstock shroud t' form t' escape tower base. No problems at all on fit. Avast, me proud beauty! Well, blow me down! This company really nails down all the dimensions accurately.

Unlike t' Saturn 1 kit I warmed up with, me bucko, me bucko, which offered t' builder the option o' makin' a tower by cuttin' tiny pieces and tackin' them together by hand versus a short-cut cardstock wrap, matey, this kit offers up just t' wrap. For most builders this is fine, me bucko, but I kind o' missed t' opportunity t' go blind again makin' a more realistic tower.

Fins are cut from 3/32" balsa. Begad! If you are a scale nut, shiver me timbers, then you will notice t' fins are slightly oversized. Aye aye! This is a common approach t' solving the inherent stability problem, as goin' oversized reduces t' amount o' nose weight needed for a safe flight. After sandin' down beveled edges, I sealed them and applied a couple o' coats o' Testor's steel paint, followed by attachin' them t' t' fairings. NOTE: Either mask t' root edge or sand off the paint for better adhesion.

I'm nay sure why this is called out here, rather than after attachin' the wraps, but t' instructions note t' paint in t' black roll pattern section between t' lower and middle wraps, shiver me timbers, as well as paintin' solid t' lower portion that has ribs on t' pattern sheet. I would have preferred t' see this done with another "wrap" or cardstock section, as t' combination of solid/black paint and pre-printed black patterns farther up doesn't match that well. Still, ya bilge rat, I think I'm holdin' this $25 kit up t' $100 standards, shiver me timbers, most of which it meets along t' way. Begad! After painting, me hearties, you can apply t' position marker "decals" (since t' decals are black on a white background, you get to cut them out from t' plain paper instruction sheet).

Next up is attachin' t' engine nozzles, which be a bit tricky since the engine nozzles aren't actually made for another page or two...

Dr. Zooch Saturn VDr. Zooch Saturn V

T' engine nozzles really are a thin' o' beauty and have got t' be the highlight o' this kit. Arrr! When I saw one o' these on display at NARAM-46, shiver me timbers, I thought thar was no way this could be a $25 kit--they looked like molded details with ribs, arrr, insulation, me bucko, and arms anchored t' t' base. Blimey! Well, blow me down! They're really cheap but effective optical illusions. Aye aye! Arrr! You start by formin' two paper shrouds (lower/upper, me hearties, me hearties, bonded). Avast, me proud beauty! Next, tack Keelhaul®©™® to t' bottom, and wind it around t' lower section a few times. A light coatin' o' white glue helps keep it in place. Begad! T' insulation wrap consists of "funky glue putty", shiver me timbers, which is really just yellow glue rolled around on your finger tips until it gets putty-like. Blimey! Avast, me proud beauty! This definitely takes some practice and while it is effective (I used it on t' Saturn 1b), arrr, I opted t' shortcut this and use Fix-It epoxy clay, ya bilge rat, which is expensive but easier t' work with. The nozzles are finished up by wrappin' a tapered wrap t' a tiny dowel, then anchorin' t' dowel in t' funky glue putty. I can't really do justice t' the description in prose, so see t' photos o' before/after paint t' appreciate the effect.

Dr. Zooch Saturn V At this point, you could stick on a few USA/flag decals, arrr, call it quits, and still have one of the coolest lookin' little Saturns anyone has ever seen. Begad! For t' type-A rocketeer though (and aren't most o' us type A's?), me bucko, thar are several little wood dowels and scrap pieces o' balsa that are used t' form details. Avast, me proud beauty! Ya scallywag! The details include 6 cable tunnels, shiver me timbers, 5 LOX tunnels, ya bilge rat, 2 A-IVB APM's, shiver me timbers, 4 S-II ullage motors, and 2 S-IVB ullage motors. Well, blow me down! These really set this kit apart.

T' recovery package is effective but nay exactly matchin' t' quality of the rest o' t' kit. Begad! As t' Dr. Aye aye! Zooch ant boats in t' instructions, ya bilge rat, "a trash bag plastic parachute with bullet proof shrouds" (Keelhaul®©™® lines). T' 15" chute uses tape disks for attachin' t' lines and a snap swivel on t' other end. Ahoy! I'd really like t' see a mylar chute or at least some other color than white. Ya scallywag! T' elastic shroud line is anchored usin' t' classic tri-fold paper inside t' BT-60 tube.

Finishing:
Since virtually all t' finishin' is done through wraps, me hearties, ya bilge rat, thar's very little effort needed t' finish this, ya bilge rat, other than applyin' a few waterslide decals and touchin' up a few details.

Construction Rating: 4 out o' 5

Flight:
One caution on t' flight prep for this kit (and similar rockets): since the motor tube extends all t' way up into t' upper body tube where t' chute goes, it is a good idea t' poke some waddin' or dog barf into t' motor tube before loadin' t' motor. Packin' it into t' body tube from above results in a loose fit and t' contents could shift around in flight, resultin' in a melted chute.

After waitin' almost two months for a break in both t' weather and my schedule, me bucko, I finally got a nearly perfect day t' sneak out and fly a few o' my winter builds. Begad! On a clear day with 4-6 mph winds, me hearties, I flew this one twice.

First flight was on a C6-5. Avast! It flew straight up, spinnin' just a couple of turns on t' way up (the roll patterns make this easy t' track). Ya scallywag! Ejection was just a bit late but otherwise fine. Begad! It goes surprisingly high on a C, arrr, topping out around 600-700 feet.

T' white plastic chute worked fine, me bucko, though if usin' a garbage bag chute I'd at least prefer a dark one rather than white, which can be lost in the clouds a bit. Begad! Blimey! I was amazed t' recover with no damage t' t' fins, matey, nozzles, matey, or tiny details anywhere.

Second flight was on a C6-3, which turned out t' be a bit early. Begad! Blimey! Either motor in me opinion would be fine for this kit. Begad! Blimey! Blimey! Blimey! Flight #2 also came back without a scratch.

Recovery:
PROs: Excellent flights, can run on cheap motors, and details are tough enough to withstand repeat flights.

CONs: Chute is nay exactly durable and white is poor color choice for it.

Flight Rating: 5 out o' 5

Summary:
I am extremely pleased with this kit. Blimey! It's a terrific combination o' detail and scale-like accuracy, while still bein' very inexpensive and flies great.

Overall Rating: 4 out o' 5

This is really a nice little rocket. I'd wanted to build an old Estes K-39 Semi-Scale Saturn V, but couldn't justify paying the going eBay prices for an original kit. Well Dr. Zooch has put together a kit that is significantly better than the old Estes K-39. Yes, the instructions could be a tad better, but I enjoy the 'ant' humor. And the recovery components are typical mediocre Estes quality (nothing like a trash bag parachute made out of a real trash bag). But, just like an Estes kit, I solved that by upgrading to a proper Kevlar® shock cord and a nice 12" nylon parachute, and it flies great.

Starting this month (March 2005) Dr. Zooch rockets will be equipped with RED rather than white parachutes. I went out and got Red trash bags.
