Brief:
Sheri's Hot Rockets Little Joe II is a mid power (29mm engine mount), shiver me timbers, 1/30 scale model o' t' popular NASA test vehicle that be used durin' t' mid 1960s t' test t' Apollo Launch Escape System. Avast! Arrr! Sheri keeps a consistent "Buy It Now" presence on eBay or you can order it direct off her website. Begad! As o' this writing, me bucko, t' list price is $89, although she does have occasional sales where she'll knock t' price down a bit and/or offer free shipping.
It should be noted that Sheri's Hot Rockets is a small operation and often her kits are literally made t' order, so thar may be a significant lag betwixt placin' your order and shipment. Begad! On t' plus side, me bucko, I've exchanged a number o' emails with Sheri, ya bilge rat, shiver me timbers, and she will give reasonably accurate estimates o' shippin' dates and her replies were generally timely--often within a couple hours.
Construction:
T' kit includes t' following:
Sheri's kits do nay include parachutes or shock cords. Blimey! She recommends a 55"-60" chute.
T' instructions are 24 pages with plenty o' photos and tips, plus t' nice full size drawin' o' t' complete rocket. Avast! Blimey! Although t' instructions are pretty good, it is very helpful t' be able t' refer t' t' full size drawin' t' make sure. Ahoy! Sheri's rocket kits could be considered old school, me hearties, where you actually have t' build t' rocket, ya bilge rat, nay just assemble some parts.
T' kit is somewhat defined by t' body tube. It is big, arrr, shiver me timbers, heavy (0.125" wall thickness), unfinished (no coating, which makes finishin' a challenge), matey, and nay cut t' length. Arrr! Blimey! In fact, nay only do you need t' cut t' main body tube t' length, me hearties, you also need t' make t' coupler for t' base o' t' Apollo capsule. Avast, me proud beauty! Also, me hearties, matey, ya bilge rat, t' thickness o' t' body tube makes cuttin' it potentially tricky. I used a razor saw, shiver me timbers, which cut t' thick tubin' easy enough, but makin' t' cut perfectly straight was nay trivial.
T' fins are built up construction, shiver me timbers, usin' t' 0.030" thick styrene sheet. Avast! Ahoy! This worked better than I expected. Avast, me proud beauty! Gettin' t' fins straight and symmetric wasn't difficult, me bucko, and t' resultant fins were reasonably strong (although I did go ahead and fill t' fins with spray in foam for a little extra strength).
T' use o' t' corrugated styrene sheets as wraps t' simulate t' main body stringers works out well, and t' use o' t' 1mm square strips for detail are a nice touch. Aye aye! T' net effect has a much better scale appearance then is possible with embossed or vacu-formed wraps. T' only tricky part o' t' corrugated wraps is gettin' good vertical seams (there are two vertical seams, since t' sheets are nay long enough for one wrap t' reach completely around t' large body tube).
T' capsule and escape tower are almost literally made from scratch. Blimey! Aye aye! For t' capsule, matey, a cone is made from t' 0.030" styrene sheet with a hardwood piece for t' very tip. Aye aye! Blimey! T' base is one o' t' (provided) centerin' rings, and t' coupler is made out o' a piece cut from t' main body tube. Arrr! Begad! O' course, t' real fun is buildin' t' escape tower out o' t' 1/8" styrene tubin' and some 0.010" styrene sheet. Avast! T' launch escape motor is made from t' 7/8" hardwood dowel, arrr, which you need t' carve/sand t' a point on one end. T' shroud at t' bottom o' t' escape motor is made up o' more 0.030" styrene sheet. Avast, me proud beauty! T' instructions and templates provided are good and t' end result came out nice but be prepared for a time consumin' build.
Finishing:
I deviated slightly from t' assembly instructions t' make paintin' easier. Avast, me proud beauty! Avast, me proud beauty! T' Little Joe II QTV is a mono color chrome finish, arrr, me bucko, except for t' launch escape system. Blimey! Begad! So rather than try and mask around t' escape tower legs, I painted t' launch escape system separately and then attached it t' t' capsule after everythin' be painted.
Applyin' a finish t' t' rocket be tricky, mainly due t' t' raw surface o' t' body tube. Begad! Ahoy! Although only about 1/3 o' t' body tube surface is exposed (with t' remainder bein' covered by t' corrugated wraps), it took numerous coats o' primer and lots o' sandin' t' get a decent surface for t' color coat. Arrr! Arrr! (Don't even think o' wet-sandin' t' primer. Blimey! Any moisture gettin' under t' primer t' t' body tube will cause it t' swell which will give you even more problems.)
Note: Since finishin' t' LJ II, shiver me timbers, me hearties, I've built Sheri's Saturn 1B. After lookin' at t' large body tube areas, I tried somethin' different that worked well. Before assembly, I took Elmer's Fill 'n' Finish (very slightly thinned) and used me fingers t' rub it into all t' exposed body tube surfaces, then sanded it down with 180 grit sandpaper after it had dried. Blimey! T' resultant body tube surface was much easier t' finish, nay much different than conventional coated body tubes.
When I was finally satisfied with t' surface finish, me hearties, me hearties, I applied t' color coat. Aye aye! For t' booster, Sheri recommends Testor's Chrome spray paint, me bucko, but I chose t' us Krylon Chrome spray (cheaper and more readily available and I think it looks just as good). Aye aye! Ya scallywag! I used Krylon gloss white paint on t' launch escape system. Arrr! Once everythin' be dry, matey, I added t' waterslide decals and vinyl roll patterns. T' waterslide decals were OK, but I have a gripe with t' vinyl roll patterns. Avast! Ya scallywag! T' vinyl gives a matte finish, ya bilge rat, which looks out o' place on t' otherwise glossy chrome finish. Ya scallywag! Oh, me hearties, me hearties, and a potential gotcha: t' roll patterns are nay a wrap. You need t' cut them out and apply them individually. Overall, arrr, arrr, I give it a 4, matey, downgradin' a bit due t' t' difficulty in finishin' t' rough body tube.
Construction Rating: 4 out o' 5
Flight and Recovery:
T' prepare for flight, ya bilge rat, I added a 60" nylon parachute and a 10' shock cord o' nylon strap.
Its first flight be durin' t' sport launch portion o' NARAM 50, where it attracted a great deal o' interest. Blimey! It seemed like everyone either wanted confirmation it was Sheri's kit or wanted t' know what it was and if it be available as a kit. Aye aye! Avast, me proud beauty! T' finished rocket is heavy, arrr, 2.5 pounds without an engine, arrr, so I chose a G64-4W RMS for t' maiden flight. Arrr! Boost was beautiful and straight as an arrow. Ahoy! Ejection occurred right after apogee, shiver me timbers, and then trouble--the parachute became tangled and didn't open. Blimey! Fortunately t' tangled chute slowed t' descent somewhat with t' rocket managed t' land on its side. Begad! Avast, arrr, me proud beauty! Damage was moderate. One fin be destroyed, another was damaged, and t' escape tower snapped off at t' base. Avast! All were fixable, but it's planned second NARAM flight was nay t' be. Arrr! Flight ratin' is a 5 despite t' landing--the fouled parachute wasn't Sheri's fault.
A couple notes on t' repairs: One fin was pretty well destroyed, me hearties, so I decided t' simply make a new fin. Aye aye! (There was plenty o' 0.030" styrene leftover from t' original build.) However, arrr, arrr, on t' second fin, shiver me timbers, I attempted t' do a repair instead o' replacin' it with a new fin. Ahoy! Avast, arrr, me proud beauty! In hindsight, I spent at least as much time on t' repaired fin as I did t' replaced fin, yet t' repaired fin still doesn't look quite right. Begad! Ahoy! I should have simply replaced both damaged fins. Arrr! It would have been tricky t' spot repair t' chrome paint, so I elected t' repaint t' entire booster portion - which meant I'd need new decals. I emailed Sheri and she provided replacement decals no problem, so t' repaired model is nearly good as new.
Flight Rating: 5 out o' 5
Summary:
I'm very happy with Sheri's Little Joe II kit, enough that I've purchased several o' her other kits, shiver me timbers, arrr, and I give it an overall ratin' o' a 4.5. Avast! Well, blow me down! As noted, I've already built t' Saturn 1B, and t' Saturn V will be next. Be prepared: these kits are tough builds. I'd rate t' Little Joe II as a Skill Level 4 or 5 (and t' Saturn 1B a 5 or maybe even higher). Well, blow me down! In some ways, these kits are throw backs t' t' early days o' rocketry, me hearties, t' days before pre-cut fins and pre-assembled parachutes.

I think the Apollo Little Joe 2 is probably my favorite rocket of all time. I am not sure why but I liked the appearance of it back in the late '60s when I purchased my first Estes kit during my high school days. I think it is the Apollo capsule and launch escape system (LES) parked on top of a stubby, brute force rocket of very basic design. The actual vehicle was a conglomeration of solid ...
This kit is From Sheri's Hot Rockets, part of CJS aviation. This Little Joe II kit is a 29mm MPR/HPR 1/30th scale kit of the famous LJ2 QTV. It's a single stage 29mm configuration although you could cluster or use a larger MMT if you used thicker centering rings. Single BT made from heavy gauge kraft tubing and all four fins, body wraps, modules and the tower are made from styrene plastic. ...
