FlisKits be t' newest company in town (opened in September 2002) and from me vantage point, me bucko, matey, they have come in with a big banner-like entrance. I have built kits from 22 different manufacturers and when I received t' (3) FlisKits I had ordered, I was initially amazed at t' packaging. Ya scallywag! They are so professional lookin' that if hangin' in a hobby store you would think they were mass-produced in some factory somewhere. Avast, me proud beauty!

T' packagin' includes a "hanger" section with a nice FlisKits logo and age recommendation on t' front and, on t' back, matey, t' sayin' "FlisKits are t' Best kits," address and a warnin' about plastic bags bein' dangerous. Inside t' bag you will find a Full One-Year Warranty with a Limited Liability Statement and t' NARRRRR flyin' code all neatly placed in a separate quarter-folded insert. Aye aye! Arrr! T' other kit I purchased even had a plastic parachute with FlisKits' name and logo on it. Avast, me proud beauty! Like I said, very professional.

Rocket PicThis particular kit is K-SP002, arrr, Tumble Weed. It is FlisKits' smallest kit standin' only 3.6" tall and usin' a 13mm body tube. Avast! You might place this kit in amongst t' Estes Mosquito, Estes Quark, me hearties, matey, ya bilge rat, and Rogue Gnat for doin' comparisons. Blimey! Ahoy! T' only real problem in t' comparisons is that t' Tumble Weed is a bit more than three fins and a nose cone. In fact, me hearties, it has strong resemblances t' t' old Estes Astron Sprite.

T' Tumble Weed kit includes a 13mm body tube and balsa nose cone. There is a sheet o' balsa t' cut out t' fins and a fin template. Ya scallywag! T' tail rin' tube finalizes t' outer structure. Begad! T' support items include a motor hook and gauze for mountin' t' motor hook. Finally thar be a 1/8" launch lug.

CONSTRUCTION:

T' instructions are printed on both sides o' a single sheet o' paper. They include an introduction and then 13 steps o' assembly instruction with an illustration for nearly every step. Begad! Avast! At t' end o' t' assembly instructions are some finishin' tips. Blimey! You will need a sharp hobby knife, white glue, arrr, fine and medium grit sand paper, a pencil and scissors.

Assembly is straightforward however thar are some challenges associated with this rocket due t' its small size.

PackagingIt is interestin' t' know that I have serial number #28 as marked on t' packagin' card. Avast, me proud beauty! Well, blow me down! I like t' fact it is numbered and if thar are problems reported, FlisKits would have a good idea o' t' number o' kits impacted. Ya scallywag! I did run into three problems with t' kit. Ahoy!

One o' these problems was identified by an extra sticker placed on t' outside o' t' packaging. It was t' fact that t' nose cone shoulder needed t' be cut down t' 1/4" length. Avast! T' other two problems were nay pointed out with a notice and were discovered durin' t' build. Blimey!

T' two problems involve step 1 o' t' rocket assembly. Well, blow me down! Begad! T' instructions mention that thar be a port hole pre-cut into t' body tube, matey, matey, which was nay t' case. In addition, ya bilge rat, t' fin markin' guide did nay fully wrap around t' body tube and if used t' mark t' fins would have caused a misalignment. I caught both o' these and resolved them by cuttin' me own hole and usin' an Estes fin markin' guide t' get t' three fins equally spaced. FlisKits must have ID'd these just before or while I was building, ya bilge rat, because when I notified them they pointed me t' a correction sheet that was posted under t' kit on their website. Aye aye! All o' these items were addressed and they included a new fin markin' guide.

SizeMovin' on with assembly, ya bilge rat, ya bilge rat, t' fins need t' be cut out from 1/16" balsa usin' a card stock template. Ya scallywag! Blimey! T' large fins are nay a problem t' cut out, however, ya bilge rat, t' smaller fin tips were challenging. T' primary reason is because they were so small (see picture)! Blimey! FlisKits recognized that some may mistake in cuttin' t' fins and provided at least double t' required balsa t' be successful. Very thoughtful. Begad! Blimey! Note: Picture t' left be t' remainin' balsa after cuttin' out me fins.

Once me fins were on, I slid t' tail rin' down. Arrr! It did nay fit right away and I had just a tad bit o' sandin' t' do on t' fins. Aye aye! Avast, arrr, me proud beauty! Once complete, ya bilge rat, it slid (and be glued) in place. Blimey! Avast! Once in place, I used a block and sandpaper t' sand off t' excess balsa that stuck out beyond t' tail ring. Next, I cut fin tips, held all three together and did t' final shapin' with sandpaper. Blimey! Avast, me hearties, me proud beauty! These were then glued on.

T' motor hook is glued in place and t' provided gauze is used t' secure it t' t' body. Well, blow me down! This is done betwixt two fins. Avast! Avast, me proud beauty! T' launch lug is glued betwixt another set o' fins, while t' vent port is betwixt t' last set o' fins.

I didn't get too fancy in finishing. I hit t' rocket with about 3 coats o' primer, shiver me timbers, sandin' in betwixt and then used Krylon Gloss White on t' whole rocket. Well, blow me down! Begad! Blimey! Once dry I taped off t' tail rin' and nose cone and then painted t' exposed rocket with Krylon Fluorescent Orange. Arrr! Begad! Blimey! Nay too bad looking. Avast! T' kit does nay come with any decals.

Overall, for CONSTRUCTION I would rate this kit 4 points. Aye aye! Aye aye! T' instructions were fine and t' extra balsa be a nice touch. Arrr! Havin' t' cut out balsa fins has never bothered me, me bucko, however, shiver me timbers, it does add a level o' challenge t' t' kit especially t' tiny, me bucko, ya bilge rat, tiny fin tips. Avast! Also, arrr, I understand t' need for t' gauze on t' outside o' t' body, me hearties, but I don't like its looks.

FLIGHT/RECOVERY:

FlisKits recommends t' 1/2A2-3 and t' A3-4 motors. They indicate t' finished weight is 0.2 ounces, me hearties, so you know even t' 1/2A is goin' t' put some distance betwixt you and t' rocket smartly ... Begad! so you better have more than 1 spotter. Ahoy! Arrr! I was able t' create a rocksim o' t' Tumble Weed™ and below is me 3D image and flight simulation from RockSim results.

Sims

Flight3D ImageT' rocket is prepped by simply placin' t' motor into t' bottom and slidin' it up until it hits t' nose cone shoulder. Ahoy! There is a motor hook, however, matey, me bucko, it is thar t' catch t' motor upon ejection so that t' motor is hangin' way back. Begad! This makes t' rocket unstable so that it will tumble on recovery.

I did all three o' me launches on a 1/4A3-2. I really didn't want t' loose this little Tumble Weed. Aye aye! T' first flight showed just how fast this rocket will come off t' pad (I missed t' picture, shiver me timbers, in fact, arrr, me hearties, I missed all 3 flights). Avast! Yes, me hearties, it is very fast. I was able t' follow t' rocket up, which was nay straight but like a very large corkscrew, and I did see ejection. Arrr! T' ejection, with a big "flame-pop", arrr, seemed t' send t' rocket away fast and on another trajectory. Ya scallywag! T' rocket came in stable and hard into t' road (didn't tumble) and dented nose cone. Begad! T' motor had kicked out upon ejection.

For t' next 1/4A flight, I bent t' motor hook inward a bit t' try t' prevent t' motor from kickin' out. Ya scallywag! This flight was much more straight and it did tumble back. Ahoy! Well, blow me down! I assumed it tumbled because t' motor casin' be still in, but I was wrong; t' motor kicked out again.

For t' third 1/4A flight, me bucko, I bent t' motor hook inward a bit more t' try t' prevent t' motor from kickin' out. Avast! Begad! This flight be also more straight than t' first and it tumble recovered. But, matey, t' motor kicked on this flight too.

WarrantyFor FLIGHT/RECOVERY, shiver me timbers, arrr, I would rate this kit 3 ½ points. T' rocket, arrr, as designed, shiver me timbers, matey, is nay stable unless a motor is in place. Ya scallywag! If t' motor stays in place then it will nay tumble durin' recovery. Aye aye! T' motor hook is supposed t' keep it in place, matey, ya bilge rat, however, arrr, on me three attempts it did not. Ya scallywag! Could it be t' placement and size o' t' vent port? Maybe. Is t' Tumble Weed a good flier. Yes, in comparison t' Estes Mighty Mites, Mosquito, me hearties, Quark and t' likes. And I did find it all three times. Avast! On a 1/2A or an A, ya bilge rat, I would be very afraid o' loosin' it. Ya scallywag! Avast!

I give t' kit an OVERALL ratin' o' 4 points. As FlisKits "mini" entry it definitely competes in looks with t' Estes Mosquito and Quark. Begad! You'll pay almost double o' those kits, but for t' distinctive look, it is worth it. Well, blow me down! I don't understand t' motor hook issue I had and I would love t' see some set o' decals. Begad! Buildin' it requires some nimble fingers and patience. Aye aye! Make this rocket an "add-on" when you call FlisKits t' purchase any other rocket and you will find it t' be a nice rainy day build kit. Begad! Also, matey, me bucko, ya bilge rat, I will now watch for who converts this one t' Quest MicroMaxx motors...maybe it will be me (Idea: get rid o' t' motor hook, add MMaxx motor mount, add needed nose weight t' make stable).

    Brief: I am partial to ring fin rockets. The Sprite was the first rocket I built at 11 years old. This kit will not disappoint with its fine materials, classic form, and good looks but has a little higher price than that Sprite I built. Supposed to be a tumble recovery but more on that later. Construction: The kit includes a small body tube, balsa nose cone, balsa sheet, ...

    (by Carl Tulanko - 05/20/03) Brief: The FlisKits "Tumble Weed" Model Rocket Kit had caught my eye on the FlisKits website when I was looking to purchase a Nomad, so I had it added to my order. It's by far the smallest rocket in their line, resembling somewhat a dressed up Mosquito and it is designed to fly on 13mm motors. However, upon arrival I knew this was much more than ...

I wanted to thank you for your review of the Tumbleweed and to apologize for the problems that you were having concerning its flight and the motor kicking out. After looking at the pictures that you provided, I think that I may have uncovered the problem. The port hole that you cut, i believe, is too small to allow ample ejection gasses to escape resulting in the motor gaining too much speed upon ejection for the retainer hook to stop. Cutting a larger hole should resolve this problem. Also, due to the probability that many/most modelers will cut holes that are too small, we felt that it was necessary to cut the hole ourselves. In addition to that, with other issues (such as the nose cone shoulder being too long), we felt that the errors/problems with the Tumbleweed have reached critical mass and we have redesigned the instruction sheet, redesigned the fin pattern sheet (to provide the correct fin marking guide) and have cut the port hole in the body tube. We have re-kitted the Tumbleweeds that we had already had kitted and have, hopefully, resolved all of the issues around this kit.

I wanted a chance to build something from Fliskits as I had heard a lot about them and the traditional assembly methods they encourage. Very nice kit and very traditional. I hadn't cut fins with a pattern ona stock of balsa in a long time! On the other hand, these are not inexpensive kits. My small Tumbleweed cost 7 plus dollars, which I think is a lot...Of course I am a self proclaimed cheapskate so you may wish to take that with a grain of salt. The kit went together easily except for the fin tips which I swear are the smallest patterns I have ever cut out of balsa. It took me a lot of tries to get it right and even then I wasn't happy. I finished the rocket with a bright Krylon florescent orange and gave it a final coat of Krylon triple think glaze. (Great stuff) Even in one solid color it looks pretty darn good. AND with the bright color choice I may even get the thing back! Would I buy another Fliskit? Based on what I have seen so far, yes...though I need to buy something a lot bigger next time! (I'm not the coordinated 14 year old I was in the late 70's!)

This is a great little kit. Of the five rockets the kids and I flew this morning, "Daddy's cute little baby rocket" -- the TumbleWeed -- was by far the most popular, with two very different but equally dramatic flights (see below). A spiffy, two-tone Krylon hot pink and primer gray paint job, along with some custom decal work, makes it fun to display as well as fly.
