Sheri's Hot Rockets Saturn V

Brief:
Sheri's Hot Rockets Saturn V is a high power (54 mm engine mount), 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). Well, blow me down! Avast, matey, me proud beauty! Sheri keeps a consistent "Buy It Now" presence on eBay or you can order it directly off her website. As o' this writing, t' list price is $449, arrr, although she does have occasional sales where she'll knock t' price down a bit and/or offer free shipping. Ahoy! However, matey, 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, arrr, shiver me timbers, ya bilge rat, 8.25" x 49"
  • 1 tube coupler, 8.25" x 3"
  • 1 upper stage body tube 5.25" x 24"
  • 1 3.125" Service Module body tube
  • 1 Styrene sheet 0.010" thick
  • 1 Styrene sheet 0.030" thick
  • 1 Fiberboard stock 1/8" x 12" x 12" (for display nozzle mount).
  • 4 ¼" ply centerin' rings (not all t' same, but they're marked)
  • 6 corrugated styrene wraps
  • 2 sheets white cardboard stock
  • 125 1mm x 1mm styrene detail strips
  • Cast resin Apollo Command Module
  • Cast resin LES rocket
  • 5 Cast resin F1 Main Engine display nozzles
  • 38mm motor mount tube with 54mm-38mm reducer rings
  • 54mm motor mount tube

  • 1 Shock Cord eyelet w/ blind nut
  • 1 Shock Cord eyelet with screw end
  • 1 piece 1/8" x 1/8" x 3" long hardwood stock
  • 1 piece 3/8" round by 6" long hardwood dowel
  • 2 piece 3/16" round by 4" long hardwood dowel
  • 3 piece ¼" x 3/8" x 36" long square balsa stock
  • 2 piece 3/16" x 3/8" x 36" long balsa stock
  • 1 piece 3/16" x 1/4" x 18" long balsa stock
  • 2 "L" brackets with nuts/bolts/washers
  • 5 flathead brass screws
  • 2 wood screws
  • 2 ¼" launch lugs
  • 1 set waterslide decals
  • 1-¼" x 1" x 1" fiberboard anchor block for screw eyelet
  • 1/8" x ¾" x 6 ¼" plywood fin structure
  • 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, I purchased me kit shortly after it was introduced, me bucko, and Sheri subsequently made some improvements. Aye aye! Blimey! Avast, me proud beauty! Blimey! 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. Sheri be happy t' oblige. She'd upped t' price o' t' Saturn kits when she improved it, so I paid t' difference betwixt t' current price and what I'd paid. Ahoy! Blimey! Ya scallywag! Blimey! 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. Begad! Avast! As purchased, ya bilge rat, t' fairin' assemblies were manufactured from pieces o' body tube and plywood with each stringer an individual piece o' 1mm x 1mm styrene that was glued into place. Ya scallywag! Similarly all t' stringers on t' 2nd-3rd stage transition shroud were individually glued into place. 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. Well, blow me down! Ya scallywag! Blimey! One downside is that this drawin' is so big that findin' somewhere t' put it is non-trivial. Ya scallywag! Begad! Blimey! I ended up tackin' it t' t' wall...

T' 8.25" diameter main body tube is simply massive. Arrr! 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, me bucko, uncoated type. Avast, me proud beauty! 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. Avast! Begad! After it dried, I sanded it down with 180 grit and then 300 grit sandpaper. As before, this worked well, ya bilge rat, ya bilge rat, but workin' a body tube over 8 inches in diameter and 4 feet long took a long, shiver me timbers, long time. 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. Arrr! By far t' largest rocket I've built t' date. 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). Blimey! Previously, matey, t' largest rocket I'd built had been t' 1/70th scale Apogee Saturn V (yes, I do really like Saturns). Ya scallywag! Ya scallywag! While t' difference betwixt 1/70th and 1/48th may nay sound like that much, remember t' effect is three dimensional, effectively makin' Sheri's Saturn 3 times t' size o' t' Apogee Saturn. Blimey! With somethin' this big, even seemingly ordinary steps can be very time consuming. Aye aye! Nay necessarily a bad thing, me hearties, but be prepared. Blimey! This is a long, involved build.

That bein' said, t' actual build o' this rocket is relatively straightforward. Ahoy! Begad! I think it may have been easier t' build than t' SHR Saturn 1B, ya bilge rat, although it did take quite a bit longer due t' t' larger size. Ahoy! T' cast resin engine fairin' assemblies were particularly appreciated. Begad! T' original instructions devoted 10 pages t' buildin' up t' fairings. Begad! With t' assemblies, it be reduced t' markin' t' body tube and gluin' t' fairings in place. I wrapped some coarse sandpaper around t' body tube t' sand t' appropriate body tube contour t' t' fairings, matey, thick CA be used t' attach t' fairings, and then epoxy fillets were added for strength. Begad! T' fins are then simply glued t' t' fairings (again, me bucko, attached with CA then epoxy fillets). Begad! Durin' an email exchange with Sheri after me Saturn was completed, matey, matey, she suggested addin' small screws t' anchor t' fairings t' t' body tube if you plan t' use particularly high thrust engines. Avast, me proud beauty! Since mine be already finished, arrr, I didn't bother t' retrofit t' change, ya bilge rat, ya bilge rat, but if you're plannin' t' build one as a flier, it would be a worthwhile addition. Avast, me proud beauty! A more robust fin attachment may also be in order. Betwixt two flights and two cross-country shipments, ya bilge rat, 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, me hearties, arrr, ya bilge rat, t' full size construction drawin' is helpful), plus thar are several more pages o' templates and patterns for makin' t' various parts and pieces. As was t' case with t' Saturn 1B, me bucko, t' instructions for addin' additional details were weak--basically little more than "shape t' part from balsa stock per t' template", matey, although anyone capable o' buildin' this rocket really doesn't need much more in t' way o' details. Avast, me proud beauty! Blimey! T' cast resin detail parts were a nice additional, although they are nay all that detailed. Again, if you want t' make it super detailed you'll need t' modify or make parts from scratch. Havin' already decided that this be t' be a flier, shiver me timbers, I didn't worry about addin' additional details.

Like Sheri's Little Joe II and Saturn 1B kits, shiver me timbers, this kit uses corrugated styrene sheets t' simulate t' external stringers. T' corrugated sheets are pre-cut t' t' appropriate width, although with a main body tube circumference o' over 25 inches, 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). 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, 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. Blimey! Sheri's kits simply provide a solid bulkhead, ya bilge rat, and t' smaller tube is butt glued t' t' center o' t' bulkhead. It works, matey, me bucko, but it is tricky t' get everythin' correctly positioned and centered. Ya scallywag! Aye aye! In fact t' entire 2nd-3rd stage transition was tricky. Begad! T' transition shroud is made from 0.030" styrene, matey, and per t' original instructions, me bucko, t' stringers were individually glued into place, shiver me timbers, matey, which be tedious and difficult. Ya scallywag! Aye aye! With t' additional cast resin transition shroud pieces, it's a relatively straightforward matter t' fit and glue t' cast shroud pieces in place. Blimey! 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. Avast! However, me bucko, me bucko, me hearties, with t' cast resin shroud pieces on top o' t' styrene transition, t' base o' t' shroud ends up significantly larger in diameter than t' top o' t' 2nd stage, makin' for a very noticeable step. Avast! If I had it t' do over again, 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. Avast! It's big, solid, shiver me timbers, me bucko, and heavy at 8 ounces (although as it turned out, nay quite heavy enough). T' additional parts Sheri sent me included cast resin parts for t' escape tower. Ahoy! Ahoy! However, arrr, me bucko, as with t' Saturn 1B, I elected t' scratch build t' escape tower from styrene tubing. Blimey! Aye aye! I think t' scratch built tower looks better, me bucko, and I sort o' enjoyed t' challenge.

Sheri includes ¼" launch lugs, but given t' large size and weight, I felt these would be insufficient so I left them off and I fitted rail buttons. Well, blow me down! 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. Avast! I strongly recommend t' addition o' t' rail buttons--just be sure t' center them betwixt t' fairings.

Finishing:
As noted previously, me bucko, me hearties, I pre-finished t' body tubes before startin' assembly. Blimey! Blimey! But this thin' is big. Avast, me hearties, me proud beauty! Blimey! Really big. Arrr! Blimey! Begad! Blimey! It takes a lot o' priming, sanding, shiver me timbers, me bucko, and paintin' t' paint. Begad! Blimey! Avast, me proud beauty! Blimey! 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. Aye aye! Blimey! Avast, me proud beauty! Blimey! 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. Blimey! This was particularly true for t' 2nd-3rd stage transition. Despite me best efforts, me hearties, I got a lot o' bleed through o' t' black paint. Well, blow me down! A trick that I successfully used t' 'patch' t' black bleed through on white/black patterns is dry film typin' correction tape. Begad! Aye aye! It's delicate t' work with, me hearties, ya bilge rat, but it can provide straight, shiver me timbers, crisp color breaks, and t' color match is generally at least as good if nay better than touch-ups o' white paint with a paintbrush. Begad! With a coat o' clear, me bucko, t' fix is nearly invisible. 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, ya bilge rat, and come with good instructions on placement. Aye aye! (Although once again, it's time consumin' t' apply them.) After maskin' off t' chrome painted areas, a coat o' clear finished everythin' off [Note: you do not want t' clear coat chrome paint--it ruins t' chrome finish. Arrr! Been there, done that.] T' effect is striking. Well, blow me down! It be a whole lot o' work, arrr, but t' result was a really good looking, really big Saturn V model.

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

As purchased, ya bilge rat, I wonder if I would have built this kit (and if I had, shiver me timbers, thar be a good chance I would have left all those stringers off t' fin-fairings and t' 2nd-3rd stage transition). Aye aye! But t' post-purchase improvements make it worthwhile. Well, blow me down! Ahoy! 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. I'd rate it betwixt a 3 ½ and 4. Givin' it t' benefit o' t' doubt, matey, I'll call it a 4.

Construction Rating: 4 out o' 5

Flight:
As previously noted, Sheri's kits do nay include recovery components. Well, blow me down! Blimey! Although she recommended two 55"-60" parachutes for t' lower section, I ended up goin' with a single 90" X-form chute, connected with a generous length o' nylon strap. Ahoy! 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. Begad! After me less than successful experience with t' Saturn 1B harness, me hearties, I decided on overkill. Avast, me proud beauty! 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. 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. Aye aye! Avast, me proud beauty! Sheri includes parts for a 38mm-55mm motor mount adapter, but for it's first flight with a 38mm motor, shiver me timbers, I invested in an Aero Pack 38mm-54mm adapter. Arrr! Begad! T' Aero Pack retainer and adapter are outside this review, but they are fantastic--definitely five stars!

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

First flight be at "Fire in t' Sky 2009", better known as FITS, me bucko, a major high power launch held in central Washington over Memorial Day weekend. Aye aye! Showin' up at pretty much any launch with this rocket will make you a center o' attention, ya bilge rat, me bucko, and FITS was no exception. Ahoy! As previously mentioned, t' rail buttons proved t' be an issue when t' launch rail wouldn't clear t' fin fairings. Avast, arrr, me proud beauty! (To help hide t' black buttons I'd centered them in t' black section o' t' roll patterns.) So thar was a false start and a minor thrash while I relocated t' rail buttons. Arrr! Avast! But finally everythin' came together. Arrr! Arrr! Liftoff o' a big Saturn V is spectacular, arrr, and this was no exception. Avast! There be a slight weathercock off t' rail (remember that marginal velocity off t' rail) but t' flight was spectacular. I'm nay sure about t' altitude. RockSim said 610 ft, but it didn't look that high t' me. Perhaps me perception be fooled due t' t' large size. At any rate, ejection occurred a moment after apogee and t' chutes opened shortly thar after. Begad! There be a minor problem: t' lengthy shock cords for t' upper and lower sections become entangled so t' two sections came down together. Ya scallywag! T' main concern be that t' entangled shock cord had t' effect o' reefin' that big main parachute, shiver me timbers, so descent was a little more rapid than I would have liked, ya bilge rat, however, touchdown damage be minor. Begad! Blimey! 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! Avast! This be goin' t' be me Level 2 Cert Flight at LDRS 28. Ya scallywag! Motor selection be a 54mm J275W-S (we had a discussion at FITS, me bucko, it was agreed that t' only appropriate propellant selection for a Saturn V is White Lightning). O' concern be t' rocket CG. Arrr! With t' 38mm I211W, t' CG be already close t' t' recommended aft CG limit. Well, blow me down! Blimey! T' J275W was goin' t' be roughly a pound heavier so I'd gone t' work on t' Apollo capsule. Begad! 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. Begad! Well, blow me down! O' course this had t' undesirable affect o' makin' t' rocket even heavier, arrr, but I saw little choice.

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

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

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

Amazingly, I found it. Ahoy! 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. Blimey! I'd like t' say it be a properly devised search that yielded t' recovery, matey, but in reality it was more luck than anythin' else. After landing, t' wind had dragged it through a corn field knockin' t' escape power off in t' process, but I be able t' backtrack through t' knocked down corn and located t' missin' tower. Arrr! Ya scallywag! 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, 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. Well, shiver me timbers, blow me down! This is especially important on this big Saturn V. Well, blow me down! Begad! Even usin' a fairly generous ejection charge (over 2 grams on t' second flight), t' chute protector has yet t' leave t' body tube. Begad! Puttin' t' upper chute on t' bottom increases t' risk that t' two sections will get tangled (as happened on t' first flight), shiver me timbers, but that is definitely preferable t' t' possibility o' t' lower section parachute failin' t' exit t' rocket. Well, blow me down! Also, as t' cert flight demonstrated, 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. Begad! Blimey! Well, blow me down! Blimey! 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, me bucko, arrr, me bucko, motor retainer, matey, paint, etc.) It's big, complex, and will take a major commitment o' time t' do t' rocket justice. Begad! Arrr! I also remain less than thrilled with t' rough surface body tubes, me bucko, shiver me timbers, 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, arrr, but t' detail parts could be a little more detailed.

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

Overall Rating: 4 out o' 5
