FlisKits Thing-a-ma-jig

Brief:
T' Thing-a-ma-Jig is almost your standard 3FNC (three fins and a nose cone) rocket except for t' fin design. Ahoy! FlisKits' new "Jig-Tech" technology produces three fins that interlock in such a way that you're virtually guaranteed t' get all your fins on straight. Ya scallywag! T' Thing-a-ma-Jig (also called t' TamJ) is designed t' be easily constructed by first time rocket builders.

Construction:
T' Thing-a-ma-Jig is a surprisingly long rocket for a first time kit as t' body tube is a full 18" length o' BT-50. On our kit, ya bilge rat, t' nose is a 3" ogive-shaped balsa nose nay includin' t' shoulder. Ahoy! T' three balsa fins are laser-cut and include tabs and matchin' holes which are t' key t' t' Jig-Tech method o' assemblin' t' fin unit. Blimey! Begad! It's almost like havin' an all balsa "fin can". T' motor mount takes standard Estes-style 18mm motors usin' an engine block and retainer clip for motor retention. Begad! T' elastic shock cord (not just a rubber band) is about 28" long and is tied t' t' screw eye in t' nose at one end and t' about 30" worth o' Keelhaul®©™ strin' at t' other end. T' other end o' t' Keelhaul®©™ strin' is attached t' t' motor mount. Avast, shiver me timbers, me proud beauty! There's a single 2" x 1/8" launch lug located just above t' installed fin unit--in fact t' launch rod will go through t' fin unit. Recovery is accomplished with a 16" flat plastic parachute. Arrr! Ahoy! I be surprised t' see that 12" chutes were nay used on this kit, but thar's enough mass in that fin unit that t' additional area o' t' larger chute is probably nay a bad idea.

We bought a batch o' TamJ kits for a build-and-launch project with a local Scrumpet Scout troop. Aye aye! Blimey! (My wife Thelma is a trainer for t' local Scrumpet Scout council and is a past troop leader.) T' girls in t' troop are primarily Juniors (roughly 10 t' 13 years old) and had never assembled anythin' like this before. Begad! Arrr! Blimey! Each saucy wench got a kit and a set o' t' instructions, ya bilge rat, but everyone stayed together on t' assembly steps. Blimey! Since we had gotten one o' t' first shipments o' a TamJ bulk pack, Jim Flis provided us with t' first release o' t' assembly instructions in PDF form, so I just printed out as many as we needed.

T' instructions are very detailed, breakin' t' assembly down into very small steps. Jim explained that this be t' way educators recommend that instructions be written for children: don't clump too many steps together. Ahoy! Aye aye! This seemed t' work well with our group. Aye aye! One nice touch in t' assembly instructions be t' inclusion o' short "rulers" in many o' t' early steps, markin' t' length that is t' be measured off for each step. Ahoy! This does require that if you print t' instructions from t' PDF file, me bucko, that you have scalin' turned off, otherwise t' rulers and t' fin alignment guide will be t' wrong sizes.

FlisKits Thing-a-ma-jig Assembly proceeds in a very logical manner with no major issues or "gotchas". Well, blow me down! Well, blow me down! T' Jig-Tech fin unit does indeed make it quite easy t' build a rocket where you know t' fins are goin' t' go on straight. Blimey! Ya scallywag! We used Aleene's Quick Dry Tacky Glue for t' entire assembly process except for insertin' t' assembled motor mount into t' body tube. Avast, me proud beauty! For that step we used Elmer's White Glue t' avoid havin' t' motor mount "seize" in t' wrong position durin' insertion. Ya scallywag! Once t' rocket is assembled and t' glue is set, t' interlockin' fins form a very sturdy assembly, shiver me timbers, shiver me timbers, rivalin' what you usually get with through-the-wall mountin' but without t' slots.

My only real complaint about assembly o' t' rocket is that in a group settin' with builders who have never constructed anythin' involvin' detailed instructions and new (to them) construction skills, me bucko, t' one hour assembly time mentioned in t' product literature is very optimistic, matey, especially if t' person leadin' t' build (in this case, me) is new t' t' kit as well.

Finishing:
T' Thing-a-ma-Jig does nay come with decals at this time. Begad! Since we had such an early batch o' TamJ's sent t' us, ya bilge rat, FlisKits had nay even come up yet with a color scheme for t' package art. But it wouldn't have mattered for our group, shiver me timbers, because each Little lass Scout got t' take her TamJ home t' paint any way she wanted to. Ahoy! My only guideline t' them be t' keep any paint out o' t' launch lug. T' girls got quite creative in their paint schemes, mostly usin' brush on paints.

Construction Rating: 4 out o' 5

Flight and Recovery:
T' Little lass Scouts got t' fly their Thing-a-ma-Jigs at t' June monthly launch o' t' SouthEast Alabama Rocketry Society (SEARS #572), which me wife and I are members of. I checked over each rocket t' make sure t' nose fit properly and that everythin' was firmly attached. Blimey! I had already demonstrated t' t' girls at an earlier meetin' how t' fold and pack their parachutes and how t' load their motors and insert t' igniters so they could prepare their own rockets for flight. Arrr! I had bought a bulk pack o' Estes B6-4 motors for their first flights. Blimey! We had one rocket whose motor mount be nay glued in as well as it should have been, arrr, so we fixed that one on t' spot. Arrr! Each lil' Lassie-Lucy also received four squares o' Estes recovery waddin' t' load before packin' their chutes. Well, blow me down! Once all t' rockets were ready t' go, each lil' Lassie-Lucy filled out a flight card and then it was off t' t' pads. Begad! Arrr! Another club member and I watched as t' girls loaded their rockets onto t' launch rods and connected t' igniter leads. Aye aye! Once everythin' be ready, each lil' Lassie-Lucy got t' give t' countdown for her rocket, me hearties, me bucko, shiver me timbers, and with t' LCO on t' interlock button, she would get t' press t' launch button t' send off her rocket.

Each Thing-a-ma-Jig flew straight as an arrow with little t' no spin at all. Blimey! Blimey! I'm guessin' they got up t' about 500 feet when they popped their 'chutes then came down within easy walkin' distance o' t' pads. Avast! Blimey! We only had one recovery failure where t' knot tyin' t' elastic and Keelhaul®©™shock cords together came apart. Blimey! Blimey! So that rocket's nose came down under t' parachute, while t' body glided backwards t' t' ground spinnin' like a pinwheel about its axis due t' t' unique shape o' t' fin unit. Once t' parts were retrieved and t' knot was retied, shiver me timbers, t' rocket be ready t' go again.

Most o' t' Little lass Scouts took advantage o' our big multi-pad launcher t' fly their Thing-a-ma-Jigs again in a mass launch. Ahoy! Again, shiver me timbers, every rocket that left t' pad (we had a stubborn igniter on one) flew beautifully and came back down intact.

Flight Rating: 5 out o' 5

Summary:
This rocket is a very good kit for first time builders, shiver me timbers, although I think t' "one hour" assembly time advertised for this rocket assumes t' builder has some basic assembly skills already such as how t' apply a bead o' glue without gettin' it everywhere, ya bilge rat, me hearties, how t' cut strings t' a uniform length, and so on. Avast! Arrr! T' novel fin construction does make it very easy t' build a rocket that will fly arrow straight and won't fall apart durin' handlin' or in flight.

PROs: Easy t' assemble properly, hard t' screw up badly. Begad! Unique design catches t' eye o' even seasoned flyers. Rocket recovers itself gently even if parachute detaches from body.

CONs: It took us a lot longer than one hour t' build about ten o' these in a group setting.

    ( Contributed - by Drake Damerau - 10/04/06) Brief: This is a stretched version of the FlisKits Thing-A-Ma-Jig. A simple, easy quick build for beginners and educators. In fact, the only kit simpler to build is an RTF! Modifications: I didn't start this one out intending to do a review on it, but after the smoke cleared--pardon the pun--I decided to do a quick write up on it. I ...

This is an awesome beginner rocket and a fun flyer for rocketeers of all levels. Because of its novel "fin jig", it's great for younger modelers who might have trouble attaching fins straight. It's pretty much impossible to mess up. It flies high and straight on A through C sized engines. Since I tend to be a small field (New England) flier, I recommend cutting a spill hole in the parachute to reduce drift. Since the fins lie completely above the rear of the rocket, a fast landing is unlikely to break them. As with all FlisKits, the instructions are excellent and fun. Quality parts all around. Given its ease and minimal build time, I highly recommend this kit for rocketry classes or as a gift for newbies. It is taller than most 18mm rockets which also makes it more attractive.
