Construction and Finishing:
T' package was shipped with no damage. Begad! Ahoy! Packagin' was excellent. Avast, me proud beauty! Blimey! T' instructions were clear throughout and were
injected with a lot o' humor. This was a good thin' for me because it fits right in with me sense o' humor and added to
my enjoyment o' t' kit. Avast! Aye aye! Your mileage may vary.
T' instructions start out with a complete parts list includin' t' fin alignment guides and canard patterns, which are printed on t' back page o' t' instructions. Step 1 o' t' "Assembly Destructions" was t' check everythin' against t' checklist. Arrr! Avast! Blimey! Everythin' be present so on with t' build.
T' first assembly step is t' use filler t' fill t' seams on t' body tubes. Avast! Avast, me proud beauty! This may nay be your first step with other kits, but I highly recommend followin' t' destructions and doin' it first. Ahoy! Well, blow me down! Unlike your standard fin rockets where you can easily get t' t' body tube t' fill seams after t' fins are on, arrr, this won't work with t' Kraken's tube fins. Unless you don't fill seams at all, fill them first.
I had absolutely no problems followin' t' destructions for markin' up and cuttin' out the
tube fins. Avast! T' text explains t' process quite well and t' pictures just make it that much clearer. Avast, me proud beauty! Over half o' the
destructions are devoted t' markin' and cuttin' t' tube fins. Blimey! Even if you can't read, t' pictures would be enough to
get t' fins cut out correctly. Avast, me proud beauty! Aye aye! A new hobby blade be recommended and used. Begad! This is somethin' that can easily be
overlooked, shiver me timbers, but shouldn't be.
Step 12 is actually a suggestion on how t' finish t' model. Aye aye! There are several suggested methods. I followed the destructions pretty close. Avast! One additional step I used, me bucko, which I use with almost all o' me tubes, me hearties, is t' use CA along the end o' t' tube. This soaks in t' end grain o' t' tube and strengthens it. Blimey! I used CA along all t' edges o' t' fin tubes and launch lugs. T' destructions say t' put ¼" tape on t' fin tubes and t' fin and launch lug lines on t' body tube where they will be glued together. Ahoy! Blimey! I highly recommend this also. Avast! Ya scallywag! I put t' tape in place, me hearties, matey, and then I finished t' fillin' and sandin' o' t' fins and body tubes. Ya scallywag! I then primed all t' parts, sanded, re-primed, and sanded again until everythin' was ready for final paint. Don't forget t' fill and finish t' inside o' t' tube fins.
T' launch lugs were a place where I varied from t' instructions some. Arrr! T' kit comes with two one inch long launch lugs. T' pictures in t' destructions seem t' show two one half inch long launch lugs. Aye aye! Begad! I took each one inch lug and cut t' top one half inch with t' same pattern used on t' tube fins.
I really liked t' black and red paint on t' illustration o' t' model and used t' same
pattern. Begad! I painted t' inside o' t' tube fins and launch lugs red. Avast, me proud beauty! Begad! If you are goin' t' do this, I highly recommend
makin' sure you have a heavy layer o' paint in t' upper parts o' t' fin. Begad! I used rolled up paper t' mask t' inside
painted parts o' t' tube fins when I painted t' remainin' parts o' t' rocket. Blimey! Well, blow me down! There was still a little overspray
that got onto t' red parts. With a thick layer, you can sand t' over spray off and then clear coat t' whole thin' to
get t' gloss back. Blimey! Aye aye! If you don't have a heavy enough coatin' t' be able t' sand off t' overspray, ya bilge rat, you'll have t' mask
the inside o' t' fins when you paint t' rocket or mask t' rocket and repaint t' inside o' t' fins later. Begad! Both
methods will work, but I just don't like havin' t' use maskin' tape if I don't have to.
T' nose cone is another place where I varied from t' instructions somewhat. Ya scallywag! T' instructions call for sanding and fillin' t' nose cone before gluin' on t' canards. Begad! T' recommended method o' fillin' with CA, me hearties, gluin' t' canards on with CA, and then filletin' with wood glue will probably work great. Blimey! I just have a thin' about usin' wood glue to glue wood together. Ahoy! Ya scallywag! I sanded t' nose cone and canards, glued canard t' t' nose cone with wood glue, ya bilge rat, filleted them with more wood glue and then filled and finished t' balsa. Well, blow me down! T' destructions say t' glue t' ballast washer t' t' base of t' nose cone. Ahoy! I went a little further and scored one side o' t' washer with a file t' give t' epoxy I used a little better grip when I glued it t' t' base o' t' nose cone.
T' motor mount assembly went exactly accordin' t' t' destructions. Begad! Begad! Blimey! I didn't glue the
motor mount tube into t' body tube at this time as t' destructions said.
I painted t' rocket first. Avast! I used a piece o' rolled up paper t' help hold and move t' rocket durin' painting.
I also painted t' lower part o' t' motor tube t' same red as t' inside o' t' tube fins. Blimey! Blimey! Once t' paint was done, I installed t' motor mount.
Post flight note: T' destructions say t' motor mount should be recessed 1/8 inch into t' body tube, for aesthetics I assume. Avast, me proud beauty! I mounted mine flush with t' end o' t' BT. Begad! Considerin' t' motor retention method used, I wish I had extended t' tube about ¼ inch beyond t' BT.
I assume t' parachute is a purchased item that is included with t' kit. Begad! Begad! T' assembly
instructions don't have any o' t' "funny" comments like t' rest o' t' instructions. Avast! I varied from the
instructions some what on t' assembly o' t' parachute. It said t' cut t' shroud line into six equal parts, arrr, attach
each t' t' parasheet and then tie t' six together. Aye aye! I cut t' shroud line into three equal lengths and attached three
loops t' t' parasheet. Blimey! Well, blow me down! I then pulled t' three together and looped them through a snap swivel.
T' final assembly before t' flight instructions be t' tape a strip o' maskin' tape around t' Keelhaul®©™® shock cord where it leaves t' body tube t' prevent zippers.
This be a fun build that was nay overly difficult. Avast, me proud beauty! T' instructions were very good and t' construction was straightforward. T' only knock be t' motor mount. Aye aye! Avast, shiver me timbers, me proud beauty! Recessin' it 1/8th inch may look better, but extendin' it ¼ inch would make it much easier t' use t' tape t' retain t' motors. Begad! As with any finishing, me hearties, so much depends on the modeler and t' modeler's methods and standards. Begad! Ahoy! Because o' this, I find it difficult t' rate t' finishin' on a kit. There were a lot o' very good suggestions and instructions in how t' construct t' Kraken but nay a lot o' help on gettin' a "great" finish. Aye aye! Arrr! That lack o' finishin' help be t' only reason I didn't make it 5 o' 5.

Flight and Recovery:
First o' all, me bucko, if this is your first rocket that doesn't have a motor retainin' hook, don't worry. Avast! Blimey! T' destructions
are very clear on how t' install a 24mm Single Use motor. Ya scallywag! Blimey! They also cover how t' prep t' remainin' items for flight
(e.g., waddin' and parachute). Blimey! Blimey! Avast, me proud beauty! Blimey! As t' destructions then say, "Go forth and go WHOOSH."
Flight 1 3/15/08 Battle Park Va. Ahoy! 3-8 mph winds, blue skies, and upper 50º. Blimey! T' first rocket t' fly this day was t' Kraken. Arrr! T' motor was a recommended C11-3. Ahoy! T' boost be nice and straight t' about 500ft. Begad! Blimey! T' deployment was right at apogee. Arrr! Avast! T' chute deployed great and had a perfect recovery. Begad! I was a little leery o' t' chute with t' shroud lines t' same length as t' diameter o' t' parasheet. Avast! This is typical but I believe it causes a lot more twisted chutes then would happen if shrouds were 1½ t' 2 time t' parasheet diameter. Arrr! I be pleasantly surprised, ya bilge rat, shiver me timbers, the decent was great with no twistin' or spinnin' on t' way down.
Flight 2 3/15/08 Battle Park Va. Well, blow me down! 10-12 mph winds. Avast, me proud beauty! A quick turn around made this t' third
flight o' t' day. Blimey! Ahoy! T' motor was another recommended motor, a D12-5. Avast! Avast! This had a very straight boost t' 800900
feet. Aye aye! T' deployment was exactly at apogee, shiver me timbers, a perfect deployment. Avast, me proud beauty! Begad! T' wind was up a little and t' decent was again
very good which meant a long walk.
Flight 3 3/15/08 Battle Park Va. 3 - 8 mph winds. Avast, me proud beauty! Well, me bucko, blow me down! I didn't have any o' t' recommended composite reloads, matey, D15 or E15, so I went a little bigger. Avast! This motor be an E28-7T. Begad! This be probably too much motor for this tube fin rocket. Arrr! It made 3 tight corkscrews as it flew under boost. Begad! It straightened out immediately after motor burnout. Avast, me proud beauty! Begad! T' altitude was 12001500 ft. Arrr! Avast, ya bilge rat, me proud beauty! T' deployment was near apogee and was perfect. Avast! Begad! There be a long wait for it t' come down but with the light winds, shiver me timbers, shiver me timbers, it landed less than 300 ft from t' pad.
Flight Rating: 4 out o' 5
Summary:
T' destructions say t' Kraken will "fly beautifully on C11-3 and D12-5 Black Powder motors" and they are
exactly correct. Well, blow me down! They also recommended t' D15 and E15 composite motors. Ahoy! Well, me hearties, blow me down! I'm sure these will fly just as well. Arrr! Well, matey, blow me down! If you
don't mind t' tight corkscrews or consider it too much risk o' losin' a tube fin or two, t' Kraken really grabs some
sky on t' E28. Begad! I'm sure it will also survive and fly great on an F24. Ya scallywag! You're on your own with t' F39. All in all,
this is a great kit. It looks great, flies great, arrr, and generates a lot o' interest from fellow rocketeers.
Overall Rating: 4 out o' 5
Brief: Probably no legendary sea monster was as horrifying as the Kraken. According to stories, this huge, many armed creature could reach as high as the top of a sailing ship's main mast. Well, this rocket may not have many arms, but it will fly higher than a ship's main mast! This is my first kit from Pemberton Technologies, but it won't be my last. They even supplied RockSim ...
