Brief:
T' Apogee Saturn V is a 1/70th scale model o' t' magnificent NASA Saturn V moon rocket. A companion kit t' t' Apogee Saturn 1B, this is a large rocket standin' over 62 inches tall and 5.6 inches in diameter. Avast! T' large size and high level o' detailin' make this an impressive rocket. I've built two Apogee Saturn V’s - one a ‘flyer’, arrr, t' other a display model which is destined for t' "Man in Space" exhibit at t' Seattle Museum o' Flight. This review reflects t' combined experiences from buildin' both Apogee Saturn V models.

Construction:
T' Saturn V kit can be ordered directly from t' Apogee web site (or if you prefer, by phone, fax, me hearties, me hearties, or snail mail). Avast, me proud beauty! Blimey! Avast! Blimey! All parts were present and accounted for when me kits arrived, however, on t' first kit t' shipper apparently got t' box wet and some o' t' parts suffered water damage. Apogee owner Tim Van Milligan was very helpful in obtainin' replacements for t' water damaged parts.

This is a complex kit and t' parts list reflects that. In addition t' t' huge main body tube (35.4" long x 5.6" diameter), thar are three other body tubes, me hearties, shiver me timbers, four coupler tubes, me bucko, 8 sheets o' vacu-form parts, ya bilge rat, two die cut balsa sheets, 3 balsa half-round dowels, several sheets o' printed or embossed wraps, me hearties, a plastic Apollo capsule kit, me hearties, a bag o' cast resin fins and detail parts, ya bilge rat, me bucko, another bag o' five injection molded plastic F1 engine display nozzles, two nylon parachutes, matey, 2 Keelhaul®©™® shock cords, clay nose weight, me hearties, a decal sheet, arrr, some miscellaneous parts, and a CD-ROM o' instructions.

As noted, t' instructions are contained on a CD-ROM, ya bilge rat, matey, in PDF format. Begad! You'll need Adobe Acrobat Reader (to open t' instructions file) and QuickTime (to view t' video instructions). Well, blow me down! If you don't already have Acrobat and/or QuickTime, download instructions are included on t' CD.

T' video instructions are very good and informative but have some faults. Ya scallywag! First, they are somewhat time consuming--there are four hours o' t' video instructions and they can be occasionally tedious. Ya scallywag! Begad! This was definitely t' case while buildin' t' second Saturn. Blimey! Since I'd already built one, I basically knew how t' kit went together--I just needed a quick reminder o' t' details and sittin' through t' entire videos got old fast. Begad! Further, me hearties, me bucko, it can be difficult t' find a specific step in t' instructions (e.g. t' double check something) so an index would be helpful. Ya scallywag! It would also be nice if in t' step where you add t' nose ballast, ya bilge rat, arrr, it told you where t' flight prepped CG should be, as it is you need t' go t' t' (included) RockSim simulation t' find t' CG and CP data (this may have contributed t' t' CG problem I experienced). I found that at least on me computers, matey, t' video instructions ran somewhat better if I downloaded t' entire folder onto t' computer (rather than runnin' it directly from t' CD). I also ended up just puttin' me old laptop next t' t' workbench so that t' instructions were available in 'real time'. Ya scallywag! Ya scallywag! On t' plus side, shiver me timbers, arrr, arrr, this rocket is a complex, difficult, time consumin' build, me hearties, matey, and t' nicely detailed video instructions greatly improve t' odds that you'll get it right. Arrr! Avast, me proud beauty! Also, although I'm an experienced model builder, I did learn some useful new tricks and techniques from t' video instructions.

Another unusual aspect o' t' kit is that you need t' 'make' t' tube couplers. Blimey! Blimey! Although all t' tubes are pre-cut t' t' correct length, t' coupler tubes are t' same diameter as t' tubes they are intended t' fit inside. Ahoy! Blimey! It is necessary t' cut and re-glue t' tube couplers t' get them t' t' proper slip-fit diameter. Well, me hearties, blow me down! Blimey! There are nicely detailed video instructions o' this process, and it worked out quite nicely. Although havin' t' make couplers may seem strange in a kit that retails for $225, arrr, most o' t' tubes used in this kit were custom manufactured t' get t' correct scale diameter. Avast! Blimey! Begad! Blimey! Bein' able t' reduce t' number o' custom diameters needed helped Apogee keep t' relatively low volume Saturn kits affordable.

T' rocket is built as three major sections: t' main 1st stage/2nd stage 'booster' section, t' S-IVB 3rd stage (which includes t' 2nd-3rd stage transition section), ya bilge rat, arrr, and t' LEM Transition/Service Module with t' Apollo Capsule. Arrr! Most o' t' construction is fairly basic and straight forward, with t' notable exception o' those notorious vacu-form wraps. Due t' t' problems many people experience tryin' t' use t' thin CA technique for attachin' t' wraps, Apogee created instructions for usin' double sided tape t' attach t' wraps (some early instruction CDs lack these instructions, if necessary you can find them at http://www.apogeerockets.com/education/newsletter71.asp). Ahoy! Arrr! I figured I'm an experienced model builder and I could make t' CA work. Wrong, matey, arrr, at least on me first try. Arrr! Where t' wrap be simple and straight (such as t' first stage Inter-tank wrap or t' third stage wraps), shiver me timbers, t' thin CA technique worked reasonably well. However, shiver me timbers, ya bilge rat, where t' wrap had multiple protrusions along t' edges (the first stage thrust structure wrap and interstage wrap), arrr, it be an entirely different story. Ahoy! Blimey! T' protrusions simply don't want t' adhere t' t' body tube. Well, blow me down! Begad! If you get a bit too much CA on t' protrusion and then try t' use your finger t' hold it t' t' body tube, you'll glue your finger t' t' wrap (I found it quite interestin' how much better CA seemed t' adhere t' me finger than t' t' body tube). Ya scallywag! On me first Saturn, me hearties, I managed t' do an OK job on t' thrust structure wrap, but I seriously botched t' interstage wrap t' t' point thar be no way I was goin' t' get it right. Aye aye! I be so disgusted that t' nearly completed Saturn V sat on t' corner o' me workbench for 3 months before I finally decided t' rip off t' interstage wrap, order a replacement wrap from Apogee, and try again. Begad! T' replacement wrap went on much better and all was well with world until I started painting. In t' course o' primin' and sanding, I accidentally crushed one o' t' interstage wrap ullage motors. Aye aye! As this is rather easy t' do, arrr, t' instructions include a step on how t' repair this type o' damage usin' epoxy clay. Avast, me proud beauty! T' repair technique worked well until I sprayed t' next coat o' primer. Aye aye! Apparently I did nay seal well around t' repair and when t' primer seeped underneath, it caused a large section o' t' wrap t' melt. (Expletive deleted!) So I ordered another interstage wrap. Avast, me proud beauty! Begad! This time I filled t' ullage motor and external H2 line details with epoxy clay before attachin' t' wrap. Arrr! At least with me previous practice this wrap went on relatively easily, me bucko, me hearties, allowin' me t' finally finish t' model.

Apogee uses very thin plastic for t' vacu-form wraps. Begad! This be done t' help preserve a high level o' detail on t' wraps, but I think they may have overdone it. Arrr! It is characteristic o' vacu-forms that t' plastic gets thinner when formed, matey, arrr, especially around large details, shiver me timbers, arrr, and t' resultant wraps can be extremely fragile (I literally had one wrap crack when I picked it up). Avast, me proud beauty! Fillin' t' large details with epoxy clay was a big help -- I recommend this step (it doesn't add much weight) - but thar be a large amount o' handlin' involved in buildin' and paintin' this model, me bucko, matey, and even after fillin' t' large wrap details with epoxy clay I still had problems with t' interstage wrap splittin' and tearin' around t' large details. Avast, me proud beauty! Personally, shiver me timbers, I'd trade a little loss in surface detail for t' increased durability and strength o' a thicker plastic wrap.

Here are a few tips if you choose t' use t' thin CA method: instead o' your finger, use a small steel ruler (or somethin' similar) t' hold down t' wrap protrusions while applyin' t' CA--the steel is far less apt t' end up glued t' t' wrap (and if it does, it’s much easier and less painful t' remove). Avast! Aye aye! When applyin' t' CA, if a wrap protrusion doesn't adhere, don't keep applyin' more CA (it’s likely you already have too much). Use a piece o' maskin' tape t' tape t' wrap protrusion down, matey, and leave it alone t' allow t' CA t' cure. Avast! Carefully remove t' maskin' tape after 15 minutes or so -- usually t' protrusion will be glued down. If nay then try t' CA again. Tim Van Milligan recently informed me that thar be a new type o' CA glue available that is specifically formulated for use on plastics and won't melt t' wraps. I haven't been able t' find t' stuff yet, me hearties, shiver me timbers, shiver me timbers, but if you can it is probably worth a try.

Finishing:
Paintin' and finishin' o' t' Saturn V is also challenging. Avast! T' video instructions have all t' right steps and procedures for gettin' a good paint job, me bucko, me hearties, arrr, along with a multitude o' detailed drawings and pictures showin' t' paint scheme and decal placement. Ahoy! But t' bottom line is that this is a large rocket with a complex paint scheme, matey, arrr, shiver me timbers, and gettin' it right takes lots o' time, patience, skill, shiver me timbers, ya bilge rat, shiver me timbers, and perhaps a little luck. Well, ya bilge rat, blow me down! As I noted earlier, shiver me timbers, finishin' tasks such as fillin' t' body tube seams, priming, ya bilge rat, sanding, matey, and maskin' off t' roll patterns take a lot o' handlin' o' t' rocket, shiver me timbers, me bucko, and it is agonizingly easy t' damage t' wraps durin' all o' this handling. Ahoy! T' only defense is t' use extraordinary care and maybe a soft towel or blanket t' set t' rocket on while workin' on it. On t' plus side, ya bilge rat, t' fins are removable (they are a simple friction fit into t' fin-fairing) which simplifies t' paintin' o' t' fins and fin-fairings. T' kit includes decals for all t' various Apollo/Saturn V flights. Begad! T' water slide decals are very nice, ya bilge rat, and were easy t' apply without tearing. Ya scallywag! A few finishin' tips: Fine steel wool works better than sandpaper when finishin' t' corrugated wraps, me bucko, and be sure t' apply several coats o' primer t' t' cast resin parts (e.g. Avast! t' fins) t' seal t' resin and provide a proper paint surface before t' color coat. Ya scallywag! Oh, arrr, and don't use Rustoleum primer on t' wraps. Rustoleum is a fine primer, but t' stuff hates plastic--I've actually had it melt a plastic nose cone. Those thin plastic wraps wouldn't stand a chance.

Construction Rating: 4 out o' 5

Flight:
While t' kit does nay include a list o' recommended motors, me hearties, such a list would be real short--Tim Van Milligan recommends t' AeroTech G80-4T. Begad! However, me hearties, arrr, as o' this writing, me hearties, G80-4T motors are in very short supply so I tried some alternatives usin' RockSim (if you don't already have RockSim, shiver me timbers, t' instructions CD includes a demo version which is good enough for evaluatin' various engine options for t' Saturn V). Avast! Realistically, t' only other "standard" rocket motor that was suitable was a G64-4W RMS, shiver me timbers, and even that required an extended launch rod. Begad! This rocket is heavy, matey, shiver me timbers, almost into high power territory. Apogee quotes 39 ounces (w/o engine), matey, arrr, ya bilge rat, me flyer came in at 42 ounces, almost exactly 3 lbs flight prepped. Begad! Avast! I should note that t' lower booster section o' t' display Saturn V came out nearly 3 ounces lighter than t' flyer, me hearties, so perhaps I got a little carried away with t' epoxy clay and glue fillets on t' flyer. At any rate, me hearties, thar are only a few acceptable mid-power engines for t' Saturn V. Begad! Someone who has a high power certification might want t' consider modifyin' t' engine mount t' accept 38mm motors.

It took t' better part o' a year for me t' build up t' nerve t' actually fly me Saturn V (and t' find a G80-4T engine). Although I provisioned me Saturn V for 29/240 motors, I don't yet have me Level 1 Certification (it’s on t' "to do" list), matey, so t' maiden flight used t' one G80-4T engine that I be able t' find. RockSim said 470 feet and ejection 0.2 seconds after apogee, but t' results didn't exactly live up t' that. Begad! Initial liftoff was fine, arrr, ya bilge rat, ya bilge rat, but up and away t' stability was marginal, arrr, me bucko, and t' Saturn V did a large, lazy corkscrew t' an estimated 300 feet. Blimey! Avast! Ejection occurred well past apogee and at a fairly high speed, ya bilge rat, at which time t' upper and lower sections collided. Ya scallywag! T' escape tower punched a hole in one o' t' booster fin-fairings before breakin' off, ya bilge rat, while t' two parachutes became entangled with t' rocket body and only partially opened. Fortunately t' partially deployed chutes provided enough drag t' slow t' tangled mess and overall damage be minor. Aside from t' hole in one fin-fairin' and broken escape tower, me hearties, arrr, me bucko, one fin be broken off, and all t' OMS units were lost from t' service module. Begad! Aye aye! Concerned over t' apparent marginal stability, me bucko, shiver me timbers, arrr, I did a quick CG check after I'd completed repairs. Lo and behold, matey, t' CG was a full two inches aft o' where it should have been. Ahoy! With t' long delay betwixt when I finished t' Saturn V and its maiden flight, matey, I don't remember enough about addin' t' nose ballast t' figure out how I fouled it up, shiver me timbers, matey, but at least addin' some more nose ballast t' get t' right CG be an easy fix.

For t' second flight I be unable t' find any G80-4T motors, shiver me timbers, so I decided go with a G64-4W RMS. Avast, me proud beauty! RockSim predicted 475 feet and ejection 0.4 seconds after apogee, however o' greater concern was that RockSim did nay predict stable flight until 84 inches after liftoff. Well, blow me down! Aye aye! Fortunately, matey, matey, six foot long launch rods were available, shiver me timbers, so I thought I'd give it a try. Avast! T' result was magnificent. Aye aye! Apparently t' extra nose ballast did t' trick, arrr, since t' flight was near arrow straight, with t' Saturn makin' a bit o' a tail slide at apogee before t' ejection fired. Well, blow me down! Once again, me bucko, thar be contact betwixt t' sections as t' parachutes deployed, but this time contact be slight and t' chutes deployed beautifully. Begad! I actually think t' G64-4W RMS is a better match for this Saturn V--it simply looked and sounded more impressive than it did on t' G80-4T (as long as you have a long launch rod available).

Recovery:
Recovery is by two large nylon parachutes, me bucko, with t' ejection break at t' 2nd stage/3rd stage transition. Blimey! T' lower main section uses a massive 60" octagon parachute, attached by a short Keelhaul®©™® shock cord. T' upper portion makes use o' 36" hexagon parachute, arrr, attached by a Keelhaul®©™® harness that holds t' Apollo and 3rd stage horizontal (to help protect t' relatively fragile escape tower from damage on touchdown). Aye aye! T' parachutes are generously sized for t' weight o' t' rocket -- note that on t' maiden flight landin' damage was minimal even though t' parachutes never fully deployed.

Flight Rating: 5 out o' 5

Summary:
Overall, ya bilge rat, this is an absolutely spectacular model o' t' Apollo Saturn V moon rocket, me hearties, me bucko, but it is nay for everyone. Ahoy! I've built a lot o' rockets (includin' over a dozen o' t' various iterations o' t' Estes 1/100 scale Saturn V), and this is far and away t' most difficult rocket kit I've ever built. Avast! A fellow Northwest rocketeer joked that he spent 1000 hours buildin' his Apogee Saturn V, and while that number is certainly excessive, I'm sure I spent well over 100 hours buildin' each o' me Apogee Saturn Vs. Well, blow me down! But if you are prepared for a challengin' build, this Saturn V has a jaw-droppin' presence that is difficult t' describe or explain. Ya scallywag! It looks magnificent and massive just standin' there, and it simply dwarfs t' Estes 1/100th scale Saturn V model, me bucko, ya bilge rat, which isn't exactly a small rocket! While it is difficult t' put so much time and effort at risk by flyin' this Saturn V, t' result can be extremely rewarding, matey, and even seductive. I expect me flyer t' make regular appearances at our (recently re-opened) high power launch site.
