Brief:
T' Little Joe II be a NASA test vehicle used durin' t' mid 1960’s t' test t' Apollo Launch Escape System. Begad! Ahoy! Estes produced t' K-30, a 1/70th scale Little Joe II kit, arrr, me hearties, from 1968 t' 1971. Ahoy! It was another o' me favorite rockets from me youth (I even became fairly adept at buildin' that tricky wooden dowel escape tower). Well, blow me down! Ahoy! Due in part t' its relatively short production run, arrr, me bucko, shiver me timbers, original K-30 kits are now quite rare (and expensive). Ya scallywag! Avast, ya bilge rat, me proud beauty! However when I found that Apogee Components be sellin' their beautiful 1/70th scale Apollo capsule kit separately, ya bilge rat, creatin' a ‘clone’ 1/70th scale Little Joe II became a viable option.

Construction:
After downloadin' t' original Estes plans from Jim Z’s site, t' next step be t' collect t' necessary parts:

1. one body tube — BT-70H (7.15-inches long) — Totally Tubular
2. one body tube — BT-20J (2.75-inches long) — generic Estes
3. one engine block — EB-20A — generic Estes
4. one launch lug — LL-2B (2.25-inches long) — old Estes stock
5. two adapter rings RA-2070 — I be lucky and just happened t' have a set o' 20-70 centerin' rings among me 30 year old parts stash, me bucko, although I could have made some from scratch without t' much difficulty (Totally Tubular also sells a “Uni-ring” which includes t' 20-70)
6. two body wraps — Evergreen Styrene (more on this later)
7. one pattern sheet — downloaded from Jim Z and printed on card stock
8. one 18-inch parachute — generic nylon ’chute
9. two shock cords — 3/8-inch sewin' elastic
10. one decal sheet — Tango Papa (more on this later)
11. one capsule kit — Apogee Components
12. one die-cut balsa sheet — downloaded patterns from Jim Z, cut from generic 3/32-inch balsa
13. one nose cone weight — modelin' clay (more on this later)

Note that I didn’t need t' WD-2A wooden dowel — that was only necessary t' offset t' launch lug for use on a C-Rail launcher.

T' embossed body wraps presented somethin' o' a problem. Arrr! Arrr! One option was t' take some card stock and use somethin' like a butter cutlass and a straight edge t' create t' embossed effect. Blimey! However I’d tried that on a previous rocket and be nay pleased with t' result. Besides, arrr, after a couple coats o' paint, t' embossin' all but disappears. Blimey! Then I found Evergreen Scale Models Styrene Sheets — this be t' stuff model railroaders use t' build scale buildings and such. T' “Car Siding, shiver me timbers, arrr, O Scale 3 1/4-inch Spacing, ..040” thick (part number 4067) was a nice match t' t' embossed pattern. It be tricky t' work with (due t' its thickness), shiver me timbers, but t' effect was very good (details later). Aye aye! Accordin' t' t' Evergreen website, shiver me timbers, this car sidin' is also available in .020-inch thickness (p/n 2067), which would have been much easier t' work with, but I was unable t' find it locally.

For t' most part, I built t' rocket accordin' t' t' original Estes instructions. Arrr! On t' engine mount, matey, arrr, I added an engine hook, matey, me hearties, and made gussets out o' 3/32-inch balsa t' t' approximate size show in t' instructions. Begad! For t' built-up fins, I first printed out t' fin pattern sheet on card stock. Avast, me proud beauty! I then used t' pre-cut balsa templates on t' pattern sheet t' cut t' balsa fin pieces from 3/32-inch balsa, me bucko, and assembled t' fins per t' instructions. T' hardest part o' t' built up fins is t' get them symmetric, but they turned out OK. Avast, me proud beauty! I used t' think built up fins were neat, matey, but they are somethin' o' a pain t' get right. T' next time I may just make t' fins out o' balsa stock. Aye aye! T' strengthen t' built-up fins, me hearties, I ‘painted’ t' paper fin skins with some 2-hour epoxy. Avast! Arrr! I let t' epoxy soak in for about 30 minutes before wipin' off any excess.

After cuttin' t' Evergreen Styrene t' size for t' body wraps, gettin' t' relatively thick plastic t' actually wrap around t' body tube was somethin' o' a challenge. Begad! I started out by coilin' t' cut out wrap pieces as tight as practical, shiver me timbers, held thar with several rubber bands, and let them sit like that for a few days so they’d start t' hold t' shape. Aye aye! I then attached them t' t' body tube usin' 3M Super 77 ® spray adhesive, again usin' rubber bands t' hold them in place. Avast! Aye aye! I then used thin CA t' seal around t' edges o' t' wrap (usin' care nay t' glue t' rubber bands in place). Ahoy! It actually worked well — it needed just a bit o' green model putty on t' wrap joint, ya bilge rat, me hearties, but t' overall effect is quite nice, givin' a corrugated look very much like t' original. Aye aye! I glued t' fins directly t' t' plastic wrap with CA, shiver me timbers, and added a thin fillet o' epoxy for extra strength.

T' Apogee Apollo capsule is beautifully detailed, shiver me timbers, particularly t' Boost Protect Shield (BPS) portion o' t' capsule. Ahoy! Unfortunately, t' Little Joe II QTV (which t' Estes K-30 modeled) and “boilerplate” flights did nay use a real Apollo capsule. Ya scallywag! Instead, me hearties, they carried simple “boilerplate” mock-ups o' t' Apollo capsule, shiver me timbers, which lacked all o' that beautiful BPS detail. Blimey! So I carefully and tediously scraped and sanded t' BPS details until t' Apogee capsule was smooth. Note that t' very last Little Joe II flight — SC-002 — used an actual Apollo capsule and hence had all that BPS detail. Avast! However t' properly model that configuration I would also have need t' create t' Reaction Control System details, and I elected nay t' do that (maybe next time J). Avast! T' Estes K-30 instructions also add a “NCW-3” lead ballast weight t' t' escape tower tube, shiver me timbers, ya bilge rat, so I filled t' Apogee escape tower tube with clay t' get t' same effect. This ended up bein' less than completely successful — as I discover ed when it came time t' fly it (more on that later).

Finishing:
Finishin' t' rocket was reasonably straightforward. Although t' original K-30 modeled t' “QTV,” I prefer t' “look” o' t' BP-12 (like t' Estes 0892 Little Joe II kit), so that is what I modeled. I used a couple coats o' primer t' smooth out some minor imperfections in t' built-up fins and fill t' body tube spirals. Blimey! T' primer also helped ‘seal’ t' surface o' t' Apollo capsule after all that sandin' t' remove t' BPS details. I then painted everythin' gloss white, me bucko, before maskin' off and paintin' t' lower section silver. I finished it off with a set o' appropriately scaled decals from Tango Papa.

Construction Rating: 4 out o' 5

Flight:
T' recommended engines (from 1970) were A8-3, B4-2, ya bilge rat, B6-4, and C6-5 (plus t' no longer produced A5-2), ya bilge rat, however I used a C6-3 for t' first flight. Ahoy! Aye aye! T' short delay turned out t' be fortuitous — although t' initial boost off t' pad was OK, me bucko, matey, t' Little Joe II went unstable and began chasin' its tail about 100 feet up. Well, blow me down! Begad! However it did gain enough altitude that — combined with t' short delay — it deployed t' parachute and recovered safely. Well, blow me down! Apparently t' Apogee Apollo capsule is light enough (compared t' t' Estes original) that fillin' t' escape tower with clay be nay sufficient t' insure stability. Aye aye! So I stuffed some more clay into t' base o' t' Apollo capsule, such that t' CG o' t' Little Joe II, fully prepped with a C engine, shiver me timbers, matey, was 4.75-inches aft o' t' tip o' t' Apollo capsule. Arrr! Blimey! T' next flight (again with a C6-3) be perfectly stable, but this time t' parachute became entangled with t' Keelhaul®©™® heat shield I used and didn’t open. Ya scallywag! Fortunately t' damage was nay serious — one fin snapped off, shiver me timbers, and t' escape tower tube split open along t' spirals — and was easily fixed. Well, blow me down! Avast, me proud beauty! However t' damage t' t' escape tower tube did convince me that fillin' t' tube with ballast clay was nay such a good idea. Aye aye! Simply puttin' t' ballast clay in t' base o' t' capsule may be a better solution.

I give t' Little Joe II a 4 1/2 ratin' (well, after I solved t' stability issue). Well, blow me down! It is a nice flier, and it certainly isn’t t' rockets fault t' parachute didn’t open.

Flight Rating: 4 out o' 5

Summary:
T' Apogee Apollo capsule kit makes it reasonably easy t' create a 1/70th scale Little Joe II, although it is a shame t' remove all those beautiful details from t' Apollo boost protect shield. All t' needed construction materials are readily available, me bucko, ya bilge rat, and t' construction itself is nay overly challenging. Avast! Avast! This Little Joe II — once I got it stable — is a nice flier and a great ‘attention grabber.’

Overall Rating: 4 out o' 5
