Sirius Rocketry USS Atlantis

Brief:
Inspired by Star Trek, ya bilge rat, this futuristic spaceship design will draw a crowd at the pad and flies surprisingly well. Aye aye! At $60, it's a bit on t' pricey side, but it is made with quality components and design and is challengin' and enjoyable to build.

Construction:
I ordered me kit via t' Sirius Rocketry website with their flagship Saturn V kit. Avast! There was a delay o' a couple days mainly due t' t' complexity o' packing up t' Saturn kit, but within a week I had t' Atlantis piled deep within my ever-growin' build queue. Ya scallywag! After allowin' it t' properly age for a month or so, I pulled it t' t' front o' t' line and cracked into it.

T' parts list is fairly extensive, me hearties, so t' followin' is a somewhat abbreviated version:

  • Balsa nose cone and metal screw eye
  • BT-55 tube
  • 10" BT-50 motor tube and D-size metal hook
  • (4) BT-5 pod reinforcement tubes
  • Assorted wood dowels for trim
  • Vacu-formed side pod halves and cockpit top
  • 1/8" laser-cut plywood fin and top deck stock
  • 24" mylar chute kit
  • 3/16" launch lugs
  • 4 waterslide decal sheets

My kit be short t' chute, which be smartly replaced when I pointed it out. T' tubes were among t' best I've ever worked with, ya bilge rat, shiver me timbers, which took a lot of the work out o' finishing. Blimey! Blimey! Ya scallywag! Blimey! T' quality o' t' vacu-forms was very good though the edge lines o' t' pod halves were nay very clearly pronounced, shiver me timbers, leadin' t' a somewhat sloppy fit and potentially hefty rework for t' sake o' appearance.

This is labeled as a skill level 4 kit and I would agree with that assessment. Ahoy! Workin' with t' vacu-forms is probably t' most challengin' aspect to it, arrr, me bucko, and t' unusual design and assortment o' trim details adds t' the overall complexity factor as well. Excludin' some special circumstance rework (more on that later), shiver me timbers, I invested about 30 hours into this and came out o' it with a pretty resectable finish. Well, blow me down! On t' low end, ya bilge rat, me hearties, it can probably be built in about 12-16 hours without worryin' about t' cosmetics, which would be a real crime on a kit o' this calliber.

Sirius Rocketry USS Atlantis While most instructions say "read t' whole thin' first" yet are still ignored, arrr, a thorough readin' is a definite must for this kit. Begad! Begad! It really helps you get a sense o' how things go together and helps avoid some basic mistakes along t' way. Begad! I still have t' weird feelin' that t' thin' is upside down, but that's just t' way it is and I'd inevitably have wound up gettin' top and bottom confused without havin' t' end product in mind as I went.

T' instructions were well written and t' illustrations were fairly helpful although oddly placed. Ahoy! Ya scallywag! In a couple o' instances, I found myself reading somethin' on one page and havin' t' refer t' an illustration on a different (usually previous) page. Ya scallywag! On t' plus side, thar were also plenty o' helpful tips on construction and finishin' techniques right down t' specific brands and colors for paint and clear coat.

Motor mount assembly is routine: slot t' tube for t' D-hook and slide on 3 centerin' rings. Begad! One o' t' rings needs t' be notched for slippin' t' hook out o' t' way. Begad! Avast, me proud beauty! Give yourself plenty o' room on that slot. Avast, shiver me timbers, me proud beauty! T' assembly is finished up with t' attachment o' a Keelhaul®©™® shock cord anchor, me bucko, which runs most o' t' way up t' tube before switchin' over to elastic. Ya scallywag! Avast, me bucko, me proud beauty! A very nice and durable approach that is unlikely t' cause the zippers that I've run into with designs that take t' Keelhaul®©™® all t' way out t' body tube. T' finished assembly then goes into t' single piece body tube, me hearties, another nice touch that probably makes this a pain t' ship. Blimey!

Markin' t' tube is accomplished usin' a wraparound guide. Well, blow me down! In addition to the basic lines, thar are areas in t' tube that need t' be cut out for through t' wall fins.

T' "belly fin" is actually an assembly o' a center piece, two side pieces, me bucko, and an antenna dowel sandwiched in between. Avast, me proud beauty! Ya scallywag! An oval-shaped "antenna dish" completes t' assembly. This assembly becomes the first o' t' 3 primary fins.

T' two side fins are mounted through t' wall. T' gap betwixt t' BT-55 and t' BT-50 motor tube is small, so t' tab is fairly short. There are a pair of "side decks" that are trim fins, me hearties, tucked in above t' side pod fins. Avast, me proud beauty! Avast, arrr, me proud beauty! A pair o' dowels linin' t' underside finish t' lower trim, and a funky-shaped top "deck" with a vacu-form bridge completes t' top trim. Avast, shiver me timbers, me proud beauty! T' end result leaves lots o' little nooks and crannies which are a challenge t' paint.

T' pod assembly be t' most challengin' aspect o' t' kit. Aye aye! You start by bondin' together two BT-5s which are slightly different lengths for a tapered end effect. These serve as reinforcments t' t' vacu-formed pod halves on the inside. Ahoy! Begad! T' halves are cut from t' vacu-forms, me hearties, and even under bright light I had trouble determinin' where t' ends were. I went conservative (thick), arrr, and wound up with a lot o' sandin' t' trim them fairly flush. Ya scallywag! After t' sanding, I fit them over t' tubes and found a couple o' spots where thar were slight gaps. Aye aye! Anticipatin' this, t' kit includes styrene stock for cuttin' patch strips. You then have t' option o' leavin' t' strips as is for an accent stripe, me bucko, or sandin' them flush for a smooth look. Aye aye! I went for t' smooth look and even after 3 nights o' tinkering/sanding/filling, ya bilge rat, still wasn't quite satisfied with t' look and moved on despite a few small gaps and seam lines showing.

Decals

Once t' pods are assembled, you cut slots through t' BT-5 and inner pod half for through t' wall mountin' t' t' side fins. These were a real pain to tack in place and keep aligned but worth t' wait. I made t' mistake o' using yellow glue and would recommend medium CA for this instead, which will speed up the bonding. Avast! Finally, each pod gets a small trim fin mounted t' t' bottom surface.

Attachin' t' nose cone and chute completes t' assembly.

Finishing:
With such light tube spirals, ya bilge rat, I didn't bother with anythin' other than a light coat o' Plasti-Cote primer, which was actually applied and sanded down before startin' construction. Begad! I also didn't seal t' plywood although I did give it a good sandin' with 220 then 400 grit paper.

For paint, me bucko, me hearties, I went with very light coats bein' paranoid about runs and overspray around all t' crevices. I wound up usin' 4 very thin coats of primer, two gray followed by two white along with sandin' and touchin' up a bit between coats.

T' recommended color scheme for this is a light gray (True-Value Easy Color "Silver Fog"). I'm really anal retentive and trekked 30 minutes across town, passin' at least 10 other hardware stores and/or big box stores along t' way t' our city's only True Value store. Begad! Blimey! Naturally, they don't carry "Silver Fog" but did carry a darker "Pewter Gray", matey, which I went with. Aye aye! Blimey! Overall, arrr, it be a bit darker than I'd have liked and it would have been better with a light gray or even white.

Decals

T' pods get hand-painted interior trim in navy blue and a small area painted copper. T' antenna and radar dish also get a copper touch ups.

Finally, ya bilge rat, you get t' t' real cost driver for t' kit: t' decals. Ya scallywag! Blimey! There are 4 sheets o' waterslides. Blimey! Ahoy! Blimey! In anticipation o' more work than I can typically stuff into a weeknight after work/dinner/life and before bed, I approached this in batch mode, cuttin' everythin' one night, followed by a night of application, and a planned third night o' micro-sol t' seal them in. Begad! Begad! Blimey! Night one was no problem, ya bilge rat, ya bilge rat, just lots o' cutting. Avast! Blimey! Night two started well, arrr, t' first sheet of decals was among t' best I've ever worked with, absolutely clear, me hearties, tough enough t' avoid stretchin' when slidin' off t' paper, ya bilge rat, and easy t' smooth out for a wrinkle-free finish. Movin' on t' sheet #2 though, I ran into problems--the decals were opaque, matey, didn't stick as well, arrr, and when I rubbed them smooth t' ink started t' rub off. Arrr! Blimey! I contemplated whether or nay it was worth buyin' a replacement sheet while movin' on t' sheets #3 and #4 and found they were just as bad. Ahoy! Blimey! In fact, t' decals from sheet #2 even started peelin' off and curling. Arrr! Horrible decals, absolutely ruinin' what had up till now been a very enjoyable project.

I emailed Dave, who be that very night experiencin' t' same problem with a kit he be prototyping. Arrr! T' make a long story less long (too late for short), he had drop shipped a batch o' decal paper t' his printer and no one in the chain caught that t' paper supplier had switched from a thick/obvious tissue liner t' a thin/hardly noticeable liner and t' liner was nay removed. Arrr! Aye aye! My decals were printed on tissue. It took us about 3 days t' sort out t' scope and cause o' t' problem. Blimey! Within a week replacement decals were in me mailbox. T' replacements were perfect. Fortunately, t' bad decals were such trash that it only took a few minutes t' flake them off.

Decals

While t' decal experience indicates a hit t' t' quality score (although not t' fault o' Sirius), I can tell you that I was very impressed with Dave's efforts t' make everythin' right. Begad! T' replacement decal fiasco probably wiped out any hope o' profit on t' kit (as many kits were certainly affected), but he won me over as a repeat customer.

T' new and improved decals are protected by 5 very thin/light applications of Krylon clear coat. Avast! Begad! I've had very mixed results with this and confirmed with Dave before tryin' it that he actually applied this stuff. I'll say thar were no compatability problems. Begad! Ya scallywag! T' clear coats maintains a nice glossy finish.

Construction Rating: 4 out o' 5

LaunchFlight:
T' recommended motor is a D12-5, arrr, but for first flight Sirius suggests a D12-3. This is probably in case you come in above t' 9.0 ounce target weight (as mine weighed in at 9.5 ounces), and an overly long delay could deploy too far past apogee. (photo courtesy o' Scott McNeely)

With t' big fin area and weight o' t' rocket, me hearties, ya bilge rat, I was expectin' a slow flight. Aye aye! Ya scallywag! It surprised me by shootin' up fairly smartly although it weathercocked a good bit into t' 5mph winds. Avast! Deployment was definitely early and t' -5 delay would have been a better fit. Avast, me proud beauty! I'm nay too good at estimatin' low altitudes, ya bilge rat, but I would put this in t' 350-300 foot range.

Recovery:
T' chute is made by Rockethead Rockets and is very good quality for a mylar chute. Ya scallywag! In this price range though, I would have expected a lightweight nylon chute. Avast, me proud beauty! Blimey! T' chute held up fine t' t' early deployment and t' rocket descended at a reasonable rate, me bucko, landin' at t' edge o' our short grass portion o' the field. Avast! Based on its landin' angle, I would be worried about damage in the future though. Arrr! It came down first hittin' a side pod, shiver me timbers, which is fairly rugged, then kicked right over on t' 1/8" dowel antenna, which sticks out a couple o' inches at t' bottom o' t' belly fin. I'm goin' t' kick around a couple o' ideas but will try t' come up with a yoke recovery harness for flight that will keep it off t' antenna.

Overall though, it suffered no damage other than a little powder streak, which I'm goin' t' buff out before flyin' again and will protect it with a coat of wax as well.

Flight Rating: 4 out o' 5

Summary:
I was very impressed with this kit. Nay so proud o' it that I'll never fly it again but proud enough nay t' want t' overdo it and risk damagin' it. Avast, me bucko, me proud beauty! It's definitely a craftsmanship kit and its highly unusual design draws a lot of looks at t' pad.

PROs: Exceptional quality o' components, ya bilge rat, great design, outstandin' customer service, me hearties, and replacement decals were superb. I especially like t' fact that it can fly on relatively affordable D12 motors rather than havin' t' sprin' for $8-12 per flight for composites.

CONs: High price, shiver me timbers, poor decals slipped through t' system, vacu-forms were great quality but lacked sharp edge lines.

If you can afford it, me hearties, get one while you can. It's a fairly limited run kit and waitin' for another run o' kits could take a while.

Overall Rating: 4 out o' 5

    The Refit USS Atlantis is a classy update-upscale of Estes' old USS Atlantis exotic starship. The old one flew on 19mm motors, this one is set up for 21mm. It's mostly a plywood and cardboard-tube kit with some vacuum-formed plastic parts as decor.  I have to brag on Sirius' customer support. I ordered the Atlantis kit on the first of September and their website reported it shipped ...

    Brief: According to my records, my Refit USS Atlantis has been sitting in my build pile for about a year. That jives with my memory. It was one of the first kits I ordered and it has been intimidating me ever since. I really wanted to build it but I wanted it to look good too. Finally, I decided to give it a try, not because I think I can do it justice but because I want it so bad. ...
