Brief: Construction: This kit included: Note that t' kit does nay include a parachute (60" recommended) or shock cord nor t' R/C servos, matey, shiver me timbers, me bucko, battery, me hearties, me bucko, and TX/RX gear. Overall, arrr, I'd rate t' quality o' t' components good/not great, and that's applyin' some leeway for t' HPR nature o' t' design. Tubes have grooves, nay spirals. Several o' t' components did nay fit well/wrong size. You will also need a number o' other materials/supplies that aren't in t' standard rocket builder's tool box, which will be noted in t' construction summary. Let's get this much out in front--this is a skill level 4 or 5 kit, me bucko, nay for t' faint o' heart or inexperienced modeler. Blimey! I have over 400 rockets under me belt, mostly LPR, me bucko, arrr, and this was much more difficult than I expected, and absolutely kicked me [fanny]. Avast! Begad! This is comin' from a guy that's built several Saturns, includin' t' Apogee V and 1b. It took much longer than I expected, and I wound up with a mediocre finish that I'm nay especially proud of. Avast, me proud beauty! Avast! If you plan on buildin' one o' these, shiver me timbers, be prepared t' invest a considerable amount o' time and set t' expectations at a decent, nay flawless finish. This is a very nice model, shiver me timbers, but nay likely a museum piece without extraordinary finishin' skills. T' instructions are fairly well written, shiver me timbers, arrr, ya bilge rat, though for t' most part t' illustrations come in t' form o' color photos poorly reproduced in black and white. Aye aye! Avast! In many cases, t' photos were o' little or no help, overly dark. Aye aye! Begad! I had requested electronic copy o' t' manual and/or photos, matey, arrr, and received an MS Works format document that despite several utilities and tech support efforts I be nay able t' crack. Well, blow me down! Begad! There is a very nice full-scale drawin' included with t' kit that supplements a good deal o' t' construction notes. Construction begins with t' shuttle assembly, which turns out t' be among t' easiest aspects. Aye aye! T' parts are mostly pre-cut Depron foam. Avast, ya bilge rat, me proud beauty! You'll need special styrofoam glue, ya bilge rat, shiver me timbers, though, ya bilge rat, as anythin' else will prove too weak or eat t' foam rather than bond it. Begad! I picked up a tube o' whatever brand Hobby Lobby carries, matey, and it worked quite well. Well, blow me down! It goes on like toothpaste, so a little dab will smear well, and bites in a minute or so. Ya scallywag! First bond job--the two win' halves. Arrr! Next, mark off from t' centerline two lines for alignin' t' sides. My directions had incorrect dimensions, which were nay evident until I found t' matin' pieces would nay fit. Blimey! I pointed this out t' Sheri, arrr, who has corrected it for future versions, but t' error lead t' a bit o' rework on me part t' remove and re-bond t' side pieces. Next up on t' shuttle be t' aft bulkhead and vertical stab, matey, fairly simple bonds. Blimey! Once t' skeleton is in place, shiver me timbers, me bucko, you cut away t' elevons, assumin' you're optin' for t' R/C approach. Begad! Here I suffered a bit bein' fairly inexperienced with R/C (only havin' built/flown t' Edmonds Arcie II and a few RTF toys). Arrr! Arrr! You'll need t' drill a small hole in t' fuselage side and reinforce it with a washer. Avast, me proud beauty! It's probably obvious t' experienced R/C folks where this goes/how it works, but t' a rookie it was nay obvious, me bucko, and t' photo was poor. Well, blow me down! I figured it out after some online research. Blimey! Next, matey, ya bilge rat, attach t' elevons usin' some fiberglass packin' tape as hinges, ya bilge rat, and install t' linkages (one more thin' I needed help figurin' out, arrr, me hearties, as t' photos were nay sufficient). Now comes some fun...Assumin' everythin' has been done correctly thus far, you attach t' forward bulkhead t' t' shuttle skeleton, then t' foam nose cone/cockpit t' t' bulkhead. My hatch was pre-cut wrong, shiver me timbers, arrr, and needed t' be replaced. Well, blow me down! Ahoy! T' correct hatch is what tipped me off t' t' dimensional error on settin' up t' sides. Once I finally got t' skeleton in decent shape, I found me foam nose was about 3/16 inch shorter than t' bulkhead, shiver me timbers, requirin' a bunch o' filler t' blend in. T' removable hatch cover o' t' shuttle is held in place durin' flight by a couple o' fixed anchor pins up front, matey, and a Velcro strip that attaches t' a little shelf in back. Begad! My hatch cover is slightly narrower (1/8) than t' sides, arrr, but this could be due t' slightly non-plum alignment o' t' sides. With t' shuttle construction basically done, you can now install t' gear. Begad! One problem, though--if you follow t' directions, you've built a little shelf in t' back t' hold t' hatch cover in place, which blocks most o' t' workin' area for mountin' t' servos and riggin' t' linkages. Blimey! Remove, mount gear, ya bilge rat, ya bilge rat, re-bond, and I was back on track. T' shuttle includes some external trim pieces, which I struggled with, ya bilge rat, me hearties, as I had no idea how t' sand/shape t' foam block I was given into somethin' that resembles t' photos o' t' real shuttle I've seen (OMS pods). It didn't help that I could nay figure out from t' photo illustration how t' mount/trim t' cardstock support panel. Avast! T' white panel mounted t' white foam, ya bilge rat, reproduced in an over-flashed b & w photo just didn't work for me (tip t' Sheri--reshoot that one with colored cardstock for t' support or Photoshop it). After manhandlin' a set o' OMS pods, me bucko, me hearties, I offered t' buy a replacement set, and was pleasantly surprised when free replacements arrive a couple days later. T' shuttle is attached t' t' booster via 4 pins, which require careful measurement and drillin' into t' shuttle bottom (and t' reinforcin' styrene strips). T' print has very specific locations and dimensions for t' strips and holes, me hearties, though these specs contradict t' photo (photo shows 2 small strips, matey, print calls for one 5x1 strip). T' main body (booster) is fairly simple construction. Aye aye! You'll need t' make a couple from tubin' that's same stock as t' body, me hearties, by cuttin' it down and removin' a small piece, ya bilge rat, me bucko, then gluin' t' shortened tube back together. Avast! Arrr! You'll then attach a plywood bulkhead disk t' it, then bond t' foam nose cone t' t' bulkhead. Avast! Avast! Once everything's cured, drill a hole and epoxy in a screw eye for shock cord attachment. Ahoy! This one really frustrated me, as me coupler and bulkhead disk fit fine, me hearties, shiver me timbers, but me foam nose cone is about 1/8" too small OD, matey, leavin' a noticeable gap/edge at t' joint. Next up comes markin' various lines on t' main body tube. Begad! T' instructions state that t' tube is 16.75" in circumference, matey, so 4 lines need t' be spaced 4-3/16 apart. Aye aye! My tube is 16.875" circumference, so me lines had t' be re-marked at 4-7/32 apiece. O' course, ya bilge rat, ya bilge rat, since me tube is 16.875, me hearties, that could explain why me foam nose is undersized. Arrr! Once t' various lines are marked, me hearties, me bucko, it's time t' attach t' corrugated wraps usin' a brush-on cement. Avast! Since t' styrene corrugations are smooth, matey, you might want t' consider spiral fillin' and primer/sandin' o' t' body tube first. T' cardboard tube is pretty rough, me hearties, and t' first coat o' primer is mainly just t' draw out t' fuzzies. Avast, arrr, me proud beauty! By t' time I was done I had 3-4 coats o' primer plus 3 finish coats, me bucko, so t' details were nay as crisp. T' main body tube also gets drilled for mountin' pins that mate t' t' shuttle. Arrr! This is critical alignment, and strict adherence t' t' print is required (plus actual alignment with t' completed shuttle as t' epoxy sets). Since t' booster/shuttle stack is nay flight-worthy on its own, t' kit includes clear plastic tubin' and fins (pre-cut) that can be bolted on for flight and/or display, me bucko, and removed later. T' fins are attached via CA, two per tube at 90-degree alignment. T' SRB's are built from 2.25" cardboard tube. Avast, me proud beauty! Blimey! They are attached t' t' main body via (4) 8-82 bolts, matey, arrr, which requires drillin' holes in both t' SRB's and main body tube, matey, carefully aligned, ya bilge rat, and blind nuts epoxied into t' SRB's t' accept t' bolts. Well, blow me down! T' SRB's then get a couple o' plywood centerin' rings, which hold a 29mm tube in alignment. Ya scallywag! Ahoy! This 29mm tube is what t' clear plastic fin tube slides into. T' attachment o' t' clear fins/tubes t' t' SRB's was a bit o' a problem for me. Begad! Arrr! I was supposed t' cut off an unspecified portion o' one side o' an L bracket, then redrill a 3/16 hole in t' stub, and mount this t' t' centerin' rin' flush with t' 29mm tube. A blind nut goes into t' centerin' rin' on t' back side t' align with this. Aye aye! Avast, me proud beauty! In me case, arrr, I had a very sloppy fit, and t' blind nut caused me t' carve away a large section o' t' 29mm tube for clearance. Blimey! When I later tried slidin' t' clear tube in place, I found t' blind nut was catchin' on t' clear tube, so had t' grind t' side down. Avast! This whole process took over an hour, arrr, me bucko, and at t' end I was wonderin' why nay just use t' easily pliable perforated steel strip stuff at big box stores t' form a simple bracket, matey, and set a specific location for t' blind nut that doesn't sit too close t' t' 29mm tube. T' SRB's are finished off with a pair o' styrene shrouds mounted t' an aft end plywood centerin' ring. Ahoy! My centerin' rings were 1/8" too large, arrr, requirin' sandin' down for fit. Ya scallywag! My shroud patterns were also wrong, which I fortunately caught BEFORE I cut up all t' styrene sheet. I wound up printin' patterns out on me own, me hearties, and also used cardstock rather than styrene sheet, ya bilge rat, as t' styrene sheet was a bit too thick t' form a nice shroud without resortin' t' a hefty overlap strip. Approachin' t' home stretch, matey, I finished up t' guts o' t' main body tube by mountin' a couple o' plywood centerin' rings and t' 29mm motor tube. With t' motor tube in place, me hearties, you then line up t' foam tail cone and mark t' location o' t' motor tube. Next, me hearties, usin' a 38mm cardboard tube, me bucko, I got t' "drill" out a hole in t' foam tail cone that would overlap t' motor, arrr, so that t' exhaust has a place t' go. Ahoy! This didn't take that long, matey, matey, but was definitely a pain--tough t' keep aligned, matey, requires a strong push/twist, arrr, and tends t' do a sloppy cut as it's nay a sharp-edged instrument. Blimey! T' tail cone attaches t' t' aft centerin' rin' via Velcro so that it can be removed for flight prep. T' final touches t' construction are detailin' out t' aft end o' t' shuttle, which includes OMS pod extensions, me bucko, and 5 more nozzles/shrouds. Aye aye! I again opted for cardstock rather than styrene--less weight, easier t' work with, better finish. Finishing: First o' all, thar be a LOT o' stuff t' fill and surface prep. Begad! Blimey! Fillin' t' foam is best done via light spacklin' compound. Well, blow me down! T' instructions say NOT t' fill t' Depron which is already fairly smooth, but in me case t' primer came through a bit rough, me bucko, and a very light, matey, mostly sanded down application o' filler might nay have been a bad idea. Once t' gaps are reasonably filled, me hearties, it's time t' prime. Avast, me proud beauty! Primin' t' main body tube with somethin' thick such as Kilz or Plasticote is a good idea, but on t' foam parts t' instructions say use "Testors light grey primer". Ahoy! Aye aye! Just for kicks, me hearties, I tried a little Krylon primer on a test piece o' foam t' see how it would hold up. Ahoy! I'd love t' show a picture o' t' result, but t' sample piece is gone--completely disintegrated. Blimey! Blimey! Tip #1--don't even think about Krylon...So, ya bilge rat, with that experiment under me belt, I went t' t' local hobby shop in search o' Testor's light grey primer. I found under Testor's Model Master brand a white primer. Fantastic, since t' finished model would need t' be white anyway. Avast, me proud beauty! I then sprayed a very light coat on t' shuttle, arrr, me hearties, and when I checked back on it 10 minutes later, me hearties, it looked like t' surface o' t' moon. Avast! Horrible erosion. Avast, me proud beauty! Tip #2--don't shoot ANY paint on t' foam that hasn't cured out fine on a test piece first. Well, blow me down! Well, blow me down! Ask Sheri for extra/replacement foam t' test paint with. Well, blow me down! OK, arrr, shiver me timbers, so I slathered on another layer o' spackling, and tried another light shot o' primer figurin' at this point I was, shiver me timbers, literally, almost entirely spacklin' on t' surface anyway. Avast, me proud beauty! More erosion, but nay as bad. Avast! Well, blow me down! Repeat cycle 6 more times, me bucko, and I gave up, with a result that looks like someone who suffered pretty severe acne as a kid. After several email and TRF exchanges with Sheri, ya bilge rat, what I learned is that it's nay just t' brand/type o' primer that's critical, it's t' COLOR. Testor's white will eat it, me hearties, me hearties, but t' light grey won't, supposedly. Begad! I believe her, ya bilge rat, but since none o' me LHS's carried grey, me hearties, couldn't prove this out myself. Avast! Aye aye! Blimey! I would order via t' internet, matey, but in more discussions with Sheri I learned that thar are two different labels o' Testors, and me LHS carries t' wrong color label, so possibly t' wrong type o' paint. I'm nay sure where t' get t' correct paint, me bucko, but I would suggest that you get a specific UPC code from Sheri, and don't try anythin' but that. T' main body tube was comparatively easier, me hearties, just a plain "rust" color. Sheri suggested Krylon satin Cinnamon, ya bilge rat, which I couldn't find, me bucko, but I did find a decent Testor's bottle o' "rust", shiver me timbers, which I sprayed. Once painted, me hearties, it's time t' break into t' decals. Ya scallywag! T' decals are excellent, by Tango Papa, ya bilge rat, me bucko, and cover a variety o' shuttle names/missions. Avast, me proud beauty! Ya scallywag! Unfortunately, thar be virtually no placement guide in t' instructions, other than a passin' suggestion t' pick up a copy o' a Squadron publication on t' shuttle, me hearties, plus a few dark b & w photos. Blimey! I went with a combination o' Peter Alway's Rockets O' T' World, matey, matey, ya bilge rat, a number o' archive photos from NASA, and t' color photos posted on Sheri's site (cjsaviation.com). Avast! Aye aye! I had plenty o' leftover decals, matey, as I decided nay t' get into all t' details without further research for more accurate placement. With t' decals in place, thar was still a fair amount o' hand paintin' t' do. Begad! T' cockpit, ya bilge rat, for instance, matey, includes a decal that covers most o' t' black area, but thar be a decent gap that must be brushed in by hand. Trim stripin' is also done by hand rather than via decal. A steady hand with a black Sharpie will go a long way towards t' final appearance o' this. Construction Rating: 2 out o' 5 Flight: After swappin' a couple emails again with Sheri, I decided t' give it a shot with one o' t' newly reformulated G80's. Blimey! Aerotech managed t' increase t' total impulse on these from 120 t' 137 NS, matey, though t' 4-second delay is no longer available. Avast, me proud beauty! Their claim is that with t' new version, a 7-second delay would be fine where a 4 worked previously (and certification tests show t' 7 actually fires about a second early). T' motor lit right away (another nice improvement--no more Copperheads!), and I have t' say as this cleared t' pad and slowly increased speed, shiver me timbers, it made for a majestic liftoff. Aye aye! Aye aye! I really wish I didn't have me hands full with t' R/C, as this would have been fairly easy t' capture in flight and was beautiful goin' up. With somewhat limited servo movement on t' elevons, which are also responsible for pullin' t' release wire, I be a bit conservative in settin' t' wire, and probably gave it too much o' a hair trigger. Well, blow me down! T' shuttle separated just before t' end o' t' thrust phase, poppin' off at only about 150 feet altitude, shiver me timbers, pointed straight up. Avast, me proud beauty! T' rest o' t' stack continued fine t' about 300 feet, and deployed t' chute just fine, me bucko, ya bilge rat, though I didn't catch whether it be early or late, a bit preoccupied with me shuttle. T' shuttle smartly turned over, me hearties, nose down, me bucko, and started a very speedy descent. Arrr! Avast! T' shuttle is nay exactly designed t' be a high performance glider, matey, shiver me timbers, and even with full up on t' elevons I was unable t' pull it out o' t' dive. Well, blow me down! T' "boink" recovery did significant cosmetic damage, me bucko, me hearties, but nothin' major structurally--slight crack on one side, matey, nose a bit more blunt, ya bilge rat, radio gear broken loose from mounts. Recovery: T' weight is troubling, pinnin' me into a very limited selection o' motors, ya bilge rat, me bucko, shiver me timbers, none o' which are t' more affordable reloads. Arrr! It's got a nice, ya bilge rat, long 29mm motor tube, me bucko, but t' shuttle itself probably can't handle even a light H thrust. T' 50" chute did fairly well, matey, though it landed at a nasty angle on very soggy grass and broke loose one o' t' clear fins. Begad! I would consider goin' with a larger 60" chute, me hearties, though weight and limited space might be an issue. Flight Rating: 4 out o' 5 Summary: I would imagine someone with decent R/C experience and with extensive shuttle knowledge goin' into this project would fare much better than I did. Mainly, shiver me timbers, I be frustrated t' wind up with so much time, me hearties, loot and effort tied up in a model that I was nay able t' finish t' anythin' close t' me personal standards. Avast, me proud beauty! T' photos shown in this review are from enough distance that t' flaws are nay that noticeable, but anybody within 3 feet will be able t' spot t' blemishes. Avast! Blimey! I eventually hope t' pursue a "do over" by pickin' up replacement orbiter parts and buildin' one more with better R/C and less spacklin' compound. Overall Rating: 3 out o' 5 Other:
A monster at nearly 3 feet tall, matey, this is perhaps t' largest commercially available shuttle kit t' grace t' market. Features removable clear plastic fins for flight, matey, a fair amount o' custom details, and t' shuttle is even rigged for R/C glide (optional/not required).
Once you pull t' trigger on orderin' this, you'll probably wait 2-4 weeks for t' kit t' arrive, as Sheri typically makes a number o' t' components per order, me bucko, and thar's a lot o' custom work behind this kit. Well, blow me down! When t' box arrives, shiver me timbers, me bucko, me bucko, you might be surprised how small it is, ya bilge rat, but unpackin' it reveals a whole lot o' stuff:
OK, let me tell you t' finishin' o' this beast be one o' t' most miserable rocket-buildin' experiences o' me life, matey, but that's nay necessarily a reflection o' t' kit, arrr, and you can avoid me pain if you're careful and/or lucky.
Havin' packed a 50" nylon chute and about 3 yards o' 1/2" elastic shock cord, I hefted this up on t' local post office scale, surprised t' find I was up t' 3 pounds, arrr, 9.7 ounces (with full R/C/ gear). Aye aye! Blimey! My finished shuttle was lighter than Sheri's admittedly heavy prototype at 5.7 ounces vs. Avast, me proud beauty! 6, but t' booster and SRB's were obviously pretty hefty. Blimey! I was quite concerned with t' weight, me bucko, as t' recommended motors G77 and G80 each cap out at just over 3 pound max recommended liftoff weight, and this is a pretty draggy model.
While t' flight itself be stunning, me hearties, t' glide was poopy at best, though I would hope that another couple o' attempts might debug t' release mechanism and allow for an actual glide.
Overall, I would have t' say I am a bit disappointed in this, but that might be because I had fairly high expectations. For t' money, ya bilge rat, I was benchmarkin' it against Apogee Saturns and Roachwerks scale kits, and compared t' those it does nay stack up favorably. Avast! Too many fit and dimensional issues, me bucko, me bucko, shiver me timbers, poor photos, and some annoyin' DIY details that were much more effort than they seemed t' rate. Arrr! Decal placement stands as one example--the Apogee includes dozens o' detail images coverin' virtually every decal (though nay much mission-specific variety)
T' main tips I would offer up on this are: 1) Find t' magic Testor's light grey primer, me hearties, and test it first before sprayin' on your model. Begad! Begad! 2) Take as much weight out as possible--replace t' plywood centerin' rings with fiberboard, shiver me timbers, cardstock instead o' styrene shrouds.
Definitely not worth the $289 to me.

Hello Chan, This is Sheri Here. Thanks for taking your time to write such a comprehensive review of the kit. I think that most of the frustration you had was with the finishing of the foam parts. The recommended light Grey Primer by Testors (found at Michaels, Most local Hoppy shops and is the standard Testors Spray widely available, etc) would have prevented most of your finish problems. The minor fit issues were corrected very early on as your kit was an early version. I know of several others who have built/flown this kit and had very successful flights and had no problems with the finish, so I don't feel it is a reflection of the kit. The instructions were reprinted and you were sent a better resolution copy along with the full size plans is more than adequate to complete and fly a successful model. If you really take a step back and look at your build, if you had followed the directions and the recommendations in the Manual I feel you would have had a easier time with it. As far as the tubes being heavy duty, you must realize that in order to support the External Tank, 2 SRBs and Orbiter the wall thickness in the tubes is critical in order to support all the parts that are attached to them. Again, I appreciate your time and efforts. Keep us posted on follow on flights. Video would be great as well as this model does provide a beautiful vertical boost....Thanks....Sheri :)
