Sheri's Hot Rockets Saturn V

Brief:
Sheri's Hot Rockets Saturn V is a high power (54 mm engine mount), matey, ya bilge rat, 1/48 scale model o' t' famous NASA moon rocket (Sheri also offers this Saturn V with dual 29mm engine mounts although I wouldn't recommend it as it needs t' bigger motors). Avast! Sheri keeps a consistent "Buy It Now" presence on eBay or you can order it directly off her website. As o' this writing, me hearties, shiver me timbers, t' list price is $449, although she does have occasional sales where she'll knock t' price down a bit and/or offer free shipping. Ahoy! Well, blow me down! However, as I've noted in other reviews o' SHR, most o' her kits are literally built t' order so be prepared for a wait.

Construction:
T' kit that I purchased includes t' followin' parts:

  • 1 main body tube, 8.25" x 49"
  • 1 tube coupler, me bucko, 8.25" x 3"

  • 4 Bolt/Washer/Blind nut assemblies (optional for LEM section attachment)
  • Full size construction drawing
  • 49 page Instruction manual
  • Template Manual
  • CD-ROM copy o' t' instructions with a RockSim file

Sheri's kits do nay include parachutes or shock cords--she recommends 2 x 55-60" chutes for t' lower portion and a 60" chute for t' upper portion.

As was t' case with t' Sheri's Saturn 1B, shiver me timbers, I purchased me kit shortly after it be introduced, arrr, and Sheri subsequently made some improvements. Ya scallywag! After I noticed on t' website that t' Saturn kits had been improved with more cast resin parts, I emailed askin' if I could purchase t' extra resin parts for t' Saturn V kits. Blimey! Sheri was happy t' oblige. Ya scallywag! Well, matey, blow me down! Blimey! She'd upped t' price o' t' Saturn kits when she improved it, arrr, so I paid t' difference betwixt t' current price and what I'd paid. Begad! T' additional parts for t' Saturn V were:

  • 4 engine fairin' assemblies
  • 4 fins
  • 4 piece upper stage transition shroud
  • 5 display engine nozzles (nicer than those originally included)
  • 4 "Reaction Control Systems" (the maneuverin' rockets on t' command module)
  • Escape tower parts (I didn't use these)
  • A number o' detail parts

Sheri's Hot Rockets Saturn V

These cast resin part are a vast improvement over t' original kit. Avast, me proud beauty! Well, blow me down! As purchased, matey, t' fairin' assemblies were manufactured from pieces o' body tube and plywood with each stringer an individual piece o' 1mm x 1mm styrene that be glued into place. Similarly all t' stringers on t' 2nd-3rd stage transition shroud were individually glued into place. Ahoy! Aye aye! I suspect many modelers wouldn't have bothered and just left t' stringers off.

As with t' other SHR models, t' full size construction drawin' is a nice touch--providin' quick reference when you're unsure how it should go together. Ahoy! Arrr! One downside is that this drawin' is so big that findin' somewhere t' put it is non-trivial. Avast, me proud beauty! I ended up tackin' it t' t' wall...

T' 8.25" diameter main body tube is simply massive. Ahoy! Begad! T' 5.25" diameter third stage body tube be t' same tube used in her companion Saturn 1B kit, arrr, and t' 8.25" tube is o' t' same 1/8" thick walled, uncoated type. As I did on t' S1B kit, I pre-finished t' two big body tubes prior t' assembly by rubbin' slight thinned Elmer's Fill 'n' Finish into t' tube surfaces. Ya scallywag! After it dried, me bucko, me bucko, I sanded it down with 180 grit and then 300 grit sandpaper. Avast, me proud beauty! As before, shiver me timbers, this worked well, me hearties, but workin' a body tube over 8 inches in diameter and 4 feet long took a long, long time. Ahoy! It turned out that this would become a common theme while buildin' this rocket.

Sheri's Hot Rockets Saturn V Make no mistake, this is a big rocket. Avast! By far t' largest rocket I've built t' date. Well, blow me down! Aye aye! Effectively this be t' largest Saturn V rocket you can display with a typical 8 foot ceilin' (with t' display nozzles in place, it clears me 8ft ceilin' by little more than an inch). Ya scallywag! Previously, me hearties, t' largest rocket I'd built had been t' 1/70th scale Apogee Saturn V (yes, arrr, me bucko, I do really like Saturns). Avast, me proud beauty! While t' difference betwixt 1/70th and 1/48th may nay sound like that much, remember t' effect is three dimensional, me bucko, effectively makin' Sheri's Saturn 3 times t' size o' t' Apogee Saturn. Begad! With somethin' this big, me hearties, even seemingly ordinary steps can be very time consuming. Aye aye! Nay necessarily a bad thing, ya bilge rat, me bucko, me bucko, but be prepared. This is a long, arrr, involved build.

That bein' said, t' actual build o' this rocket is relatively straightforward. I think it may have been easier t' build than t' SHR Saturn 1B, although it did take quite a bit longer due t' t' larger size. T' cast resin engine fairin' assemblies were particularly appreciated. Begad! Begad! T' original instructions devoted 10 pages t' buildin' up t' fairings. Well, blow me down! Well, blow me down! With t' assemblies, me bucko, it was reduced t' markin' t' body tube and gluin' t' fairings in place. Ahoy! I wrapped some coarse sandpaper around t' body tube t' sand t' appropriate body tube contour t' t' fairings, matey, thick CA was used t' attach t' fairings, matey, matey, and then epoxy fillets were added for strength. Avast! T' fins are then simply glued t' t' fairings (again, ya bilge rat, attached with CA then epoxy fillets). Well, blow me down! Ahoy! Durin' an email exchange with Sheri after me Saturn was completed, she suggested addin' small screws t' anchor t' fairings t' t' body tube if you plan t' use particularly high thrust engines. Ya scallywag! Since mine was already finished, shiver me timbers, I didn't bother t' retrofit t' change, but if you're plannin' t' build one as a flier, it would be a worthwhile addition. Avast! A more robust fin attachment may also be in order. Arrr! Arrr! Betwixt two flights and two cross-country shipments, I think I've knocked every fin off at least once.

T' 49 pages o' instructions for t' basic assembly o' t' rocket are reasonably good (and as noted, t' full size construction drawin' is helpful), plus thar are several more pages o' templates and patterns for makin' t' various parts and pieces. Avast, me proud beauty! Blimey! Begad! Blimey! As be t' case with t' Saturn 1B, shiver me timbers, t' instructions for addin' additional details were weak--basically little more than "shape t' part from balsa stock per t' template", although anyone capable o' buildin' this rocket really doesn't need much more in t' way o' details. T' cast resin detail parts were a nice additional, although they are nay all that detailed. Again, shiver me timbers, if you want t' make it super detailed you'll need t' modify or make parts from scratch. Ahoy! Blimey! Havin' already decided that this was t' be a flier, me bucko, I didn't worry about addin' additional details.

Like Sheri's Little Joe II and Saturn 1B kits, this kit uses corrugated styrene sheets t' simulate t' external stringers. T' corrugated sheets are pre-cut t' t' appropriate width, arrr, although with a main body tube circumference o' over 25 inches, shiver me timbers, it is necessary t' glue three sections o' styrene together t' get t' necessary length (usin' pieces o' t' 0.010" styrene as a doubler). Arrr! Attachment o' t' wraps be similar t' that for t' Apogee Saturns: tapin' t' wraps in place then usin' CA t' seal t' edges t' t' body tube.

Again, me hearties, as with Sheri's other kits, t' tube couplers need t' be cut down t' t' appropriate diameter, although at least t' main body tube coupler is pre-cut t' length. Ya scallywag! (I fear cuttin' a length off that massive 8.25" body tube would have proved challenging.)

Sheri's Hot Rockets Saturn V One step that proved somewhat difficult is centerin' t' upper stage transitions. Blimey! Most kits provide centerin' rings t' locate t' smaller diameter body tubes in t' center o' t' transition. Begad! Avast! Sheri's kits simply provide a solid bulkhead, and t' smaller tube is butt glued t' t' center o' t' bulkhead. Begad! It works, matey, arrr, but it is tricky t' get everythin' correctly positioned and centered. Ya scallywag! Well, blow me down! In fact t' entire 2nd-3rd stage transition be tricky. Begad! T' transition shroud is made from 0.030" styrene, matey, and per t' original instructions, t' stringers were individually glued into place, which was tedious and difficult. With t' additional cast resin transition shroud pieces, it's a relatively straightforward matter t' fit and glue t' cast shroud pieces in place. However, one thin' I'd change be t' attachment o' t' shroud t' t' bulkhead: per t' instructions t' shroud overlaps t' bulkhead with t' corrugated wrap at t' top o' t' 2nd stage and everythin' would match up. Aye aye! Arrr! However, with t' cast resin shroud pieces on top o' t' styrene transition, me bucko, t' base o' t' shroud ends up significantly larger in diameter than t' top o' t' 2nd stage, makin' for a very noticeable step. Blimey! If I had it t' do over again, shiver me timbers, ya bilge rat, I'd fit t' shroud t' t' top o' t' bulkhead, then cover t' bulkhead/shroud joint with t' cast resin pieces.

Sheri's Hot Rockets Saturn V This uses t' same cast resin Apollo capsule as t' Saturn 1B kit. Aye aye! It's big, solid, and heavy at 8 ounces (although as it turned out, me bucko, nay quite heavy enough). Blimey! T' additional parts Sheri sent me included cast resin parts for t' escape tower. Blimey! However, arrr, me bucko, as with t' Saturn 1B, matey, I elected t' scratch build t' escape tower from styrene tubing. Aye aye! I think t' scratch built tower looks better, and I sort o' enjoyed t' challenge.

Sheri includes ¼" launch lugs, shiver me timbers, but given t' large size and weight, me bucko, I felt these would be insufficient so I left them off and I fitted rail buttons. Begad! Avast, me proud beauty! Unfortunately I overlooked a detail when addin' t' buttons: rails are rather wide and initially I didn't provide sufficient clearance for t' rail t' clear t' engine fairing. Ya scallywag! I strongly recommend t' addition o' t' rail buttons--just be sure t' center them betwixt t' fairings.

Finishing:
As noted previously, me bucko, I pre-finished t' body tubes before startin' assembly. Ya scallywag! But this thin' is big. Begad! Really big. Well, blow me down! It takes a lot o' priming, ya bilge rat, sanding, shiver me timbers, shiver me timbers, me bucko, and paintin' t' paint. Ahoy! In fact, I went through more than three 12oz cans o' automotive primer and another three plus 12oz cans o' Krylon color while paintin' this Saturn. Begad! I did make things a little simpler by paintin' t' main rocket before addin' t' detail parts, which I'd painted separately.

Maskin' for t' black roll patterns was particularly troublesome since sealin' around t' sharply defined corrugations be extremely difficult. Avast! Blimey! This was particularly true for t' 2nd-3rd stage transition. Ya scallywag! Blimey! Despite me best efforts, me bucko, I got a lot o' bleed through o' t' black paint. A trick that I successfully used t' 'patch' t' black bleed through on white/black patterns is dry film typin' correction tape. Begad! Blimey! Avast! Blimey! It's delicate t' work with, but it can provide straight, crisp color breaks, ya bilge rat, and t' color match is generally at least as good if nay better than touch-ups o' white paint with a paintbrush. Ya scallywag! Blimey! With a coat o' clear, t' fix is nearly invisible. Aye aye! Blimey! Ya scallywag! Blimey! I then used Krylon Chrome t' paint t' fins and lower fairings and t' Command Service Module.

T' waterslide decals by Space Model Systems are beautiful, reasonably easy t' apply, and come with good instructions on placement. (Although once again, it's time consumin' t' apply them.) After maskin' off t' chrome painted areas, ya bilge rat, shiver me timbers, a coat o' clear finished everythin' off [Note: you do not want t' clear coat chrome paint--it ruins t' chrome finish. Well, blow me down! Been there, done that.] T' effect is striking. Begad! It be a whole lot o' work, but t' result was a really good looking, matey, really big Saturn V model.

Sheri's Hot Rockets Saturn VSheri's Hot Rockets Saturn V

As purchased, shiver me timbers, ya bilge rat, I wonder if I would have built this kit (and if I had, thar be a good chance I would have left all those stringers off t' fin-fairings and t' 2nd-3rd stage transition). Well, blow me down! Begad! But t' post-purchase improvements make it worthwhile. I still have reservations regardin' t' rough surface body tubes and t' detail parts could have better detail, but overall it makes for a good kit. Blimey! Well, matey, blow me down! I'd rate it betwixt a 3 ½ and 4. Avast! Givin' it t' benefit o' t' doubt, shiver me timbers, shiver me timbers, I'll call it a 4.

Construction Rating: 4 out o' 5

Flight:
As previously noted, Sheri's kits do nay include recovery components. Blimey! Although she recommended two 55"-60" parachutes for t' lower section, matey, I ended up goin' with a single 90" X-form chute, connected with a generous length o' nylon strap. Blimey! For t' upper section I went with t' recommended 60" chute with a harness t' hold it horizontal t' protect t' escape tower on landing. After me less than successful experience with t' Saturn 1B harness, matey, I decided on overkill. I drilled a hole through t' top o' t' upper stage and t' upper transition coupler, shiver me timbers, epoxied a nut inside t' coupler, and threaded a (removable) eye bolt through t' attach t' harness. Aye aye! It also acts as a positive retention for t' upper transition and Apollo capsule.

For positive engine retention I added an Aero Pack 54mm engine retainer. Sheri includes parts for a 38mm-55mm motor mount adapter, but for it's first flight with a 38mm motor, I invested in an Aero Pack 38mm-54mm adapter. T' Aero Pack retainer and adapter are outside this review, matey, but they are fantastic--definitely five stars!

With parachutes, chute protector, engine retainer, ya bilge rat, six cans o' paint, ya bilge rat, arrr, matey, epoxy, etc. Aye aye! Avast! (but less engine), this Saturn V weighed in at a whoppin' 12 pounds. Avast, me proud beauty! Aye aye! Before it was finished I'd gone into RockSim with Sheri's baseline file, arrr, me hearties, and decided an I211W-S would be ideal for t' first flight. Ahoy! Unfortunately t' weight in Sheri's RockSim file was rather optimistic, and me Saturn V be over 3 pounds heavier. Avast! Arrr! Suddenly an I211 be marginal for velocity off t' rail, me bucko, but since I'd already purchased t' motor and since a 38/480 was at t' time t' longest 38mm casin' I had, ya bilge rat, I was somewhat committed.

First flight be at "Fire in t' Sky 2009", me hearties, better known as FITS, a major high power launch held in central Washington over Memorial Day weekend. Begad! Ya scallywag! Showin' up at pretty much any launch with this rocket will make you a center o' attention, matey, arrr, shiver me timbers, and FITS was no exception. Ya scallywag! As previously mentioned, matey, t' rail buttons proved t' be an issue when t' launch rail wouldn't clear t' fin fairings. Begad! (To help hide t' black buttons I'd centered them in t' black section o' t' roll patterns.) So thar be a false start and a minor thrash while I relocated t' rail buttons. But finally everythin' came together. Ahoy! Ahoy! Liftoff o' a big Saturn V is spectacular, arrr, and this was no exception. Ya scallywag! Ya scallywag! There was a slight weathercock off t' rail (remember that marginal velocity off t' rail) but t' flight be spectacular. Begad! Ahoy! I'm nay sure about t' altitude. RockSim said 610 ft, but it didn't look that high t' me. Blimey! Perhaps me perception was fooled due t' t' large size. Begad! At any rate, shiver me timbers, ejection occurred a moment after apogee and t' chutes opened shortly thar after. Begad! Blimey! There was a minor problem: t' lengthy shock cords for t' upper and lower sections become entangled so t' two sections came down together. Aye aye! T' main concern was that t' entangled shock cord had t' effect o' reefin' that big main parachute, ya bilge rat, so descent was a little more rapid than I would have liked, however, arrr, touchdown damage be minor. Well, blow me down! T' most serious bein' one fin bein' snapped off.

Sheri's Hot Rockets Saturn VSheri's Hot Rockets Saturn V

After repairs and a cross-country shipment came t' big test. Arrr! This be goin' t' be me Level 2 Cert Flight at LDRS 28. Ya scallywag! Begad! Motor selection was a 54mm J275W-S (we had a discussion at FITS, it was agreed that t' only appropriate propellant selection for a Saturn V is White Lightning). Ahoy! Avast, me bucko, me proud beauty! O' concern was t' rocket CG. Begad! With t' 38mm I211W, shiver me timbers, t' CG was already close t' t' recommended aft CG limit. T' J275W was goin' t' be roughly a pound heavier so I'd gone t' work on t' Apollo capsule. I drilled and ground out a large cavity in t' base o' t' capsule and epoxied enough lead shot in t' hole t' raise t' total weight o' t' Apollo from 8 ounces t' an even pound. O' course this had t' undesirable affect o' makin' t' rocket even heavier, but I saw little choice.

T' LDRS cert flight became a challenge but for an unexpected reason. Avast! Blimey! Even at LDRS, a 7.5' Saturn V will make you a center o' attention and I be surrounded by photographers as I prepared t' rocket on an 8ft rail. Avast, me proud beauty! Even with t' J275, ya bilge rat, me bucko, RockSim predicted that it wouldn't reach stable velocity until a few inches before it left an 8ft rail. Begad! It was windy when t' Saturn V was launched, and I feared a weathercock off t' rail, but t' flight be magnificent and almost perfectly vertical with a slow (by mod-rock standards) boost. Arrr! Avast! Blimey! RockSim had predicted 1600 feet, matey, ya bilge rat, and that appeared t' be about right. Begad! Blimey! Motor ejection occurred right at apogee, and both chutes opened moments later t' a round o' applause. Ya scallywag! I figured I be home free. Ahoy! Avast, ya bilge rat, me proud beauty! Blimey! Wrong.

Sheri's Hot Rockets Saturn VSheri's Hot Rockets Saturn V

While t' lower half o' t' Saturn descended nicely, t' upper portion caught a thermal and started drifting. Aye aye! Arrr! At times it definitely appeared t' be goin' up. Begad! It drifted so far I lost sight o' it before it touched down. I knew I had t' try, me hearties, but with little more than a general area where I thought it came down, arrr, I was nay optimistic that I would ever see it again. If someone had asked me t' list everythin' that might have gone wrong on me cert flight, matey, I would never have even considered losin' t' rocket, arrr, but suddenly that was a very real possibility.

Amazingly, I found it. Avast! Avast! It took over four hours and two separate trips out. I found two other lost high power rockets and headed back t' t' launch area midway through t' search since I literally couldn't carry any more. I'd like t' say it was a properly devised search that yielded t' recovery, but in reality it be more luck than anythin' else. After landing, shiver me timbers, t' wind had dragged it through a corn field knockin' t' escape power off in t' process, matey, but I be able t' backtrack through t' knocked down corn and located t' missin' tower. Begad! Well, blow me down! T' result be a successful Level 2 high power certification.

Recovery:
A couple comments on t' flights: On large rockets like this that are intended t' come down in two portions, me bucko, arrr, I generally make a point t' insert t' upper section parachute first so that as t' sections pull apart, it'll be sure t' pull out t' lower section chute. Avast! This is especially important on this big Saturn V. Even usin' a fairly generous ejection charge (over 2 grams on t' second flight), matey, t' chute protector has yet t' leave t' body tube. Puttin' t' upper chute on t' bottom increases t' risk that t' two sections will get tangled (as happened on t' first flight), matey, but that is definitely preferable t' t' possibility o' t' lower section parachute failin' t' exit t' rocket. Also, ya bilge rat, as t' cert flight demonstrated, arrr, t' upper section can use a smaller chute (or if usin' a 60" chute reef it a bit).

This rocket is a fine flier that can't help but look magnificent in flight. I give it a full five stars.

Flight Rating: 5 out o' 5

Summary:
Be forewarned: buildin' this rocket takes a commitment well beyond t' $449 sticker price (plus I figure around another $200 for parachutes, motor retainer, arrr, ya bilge rat, paint, me hearties, etc.) It's big, ya bilge rat, ya bilge rat, complex, matey, and will take a major commitment o' time t' do t' rocket justice. Blimey! I also remain less than thrilled with t' rough surface body tubes, although t' strength and weight is more readily justified on a big high power rocket such as this. T' cast resin parts that were added after me original purchase are a major improvement, but t' detail parts could be a little more detailed.

I really like this rocket. Avast, me hearties, me proud beauty! Blimey! I don't know how often I will actually fly it. Well, blow me down! Blimey! Aye aye! Blimey! It's nay trivial t' put so much time, me bucko, effort, and loot at risk, arrr, but it's a magnificent flier and pretty much guaranteed t' draw a crowd. Arrr! Blimey! But perhaps t' best endorsement I can give is, should this Saturn V meet an untimely demise, I'm pretty sure I'd build another.

Overall Rating: 4 out o' 5
